Whether used alone or integrated with other Raritan solutions, the intelligent Dominion PX offers secure access with 256-bit AES encryption and strong passwords.  Dominion PX supports advanced authorization options including outlet-level permissions and LDAP/S, RADIUS and Active Directory®.  Flexible management interfaces support HTTP, HTTPS, IPMI, SMASH-CLP, SSH, Telnet and SNMP, as well as user-configurable, outlet-level delays for power sequencing.

Dominion PX Remote Power Management Solutions can be integrated with the following Raritan solutions:

  • KVM switches: Dominion® KX II and Paragon® II
  • Secure console servers: Dominion SX
  • Centralized IT infrastructure management: CommandCenter® Secure Gateway

Features

Benefits

 

Power Distribution

 

Power Sequencing
(User Defined)

In the event the PX is reset, the outlets will be turned on in a user-defined sequence at user-defined intervals to prevent tripping circuit breakers due to in-rush currents. (Applies only to PX models that support switching.)

Receptacle Status Retention

In the event of a power outage, power is restored only to those receptacles that were on before the outage. For PX models that don't support switching, power will be restored to all outlets.

Circuit Breakers

The PX uses UL 489 circuit breakers instead of fuses in 30A/32A models or higher, meeting the newest safety standard for branch circuit protection (UL60950 third edition). This eliminates the need for spare fuses and the time to replace them. Also, in many cases, a certified/licensed electrician is required to replace a fuse, whereas circuit breakers can be reset by a user.

 

Power Monitoring 

Power Metering

The PX enables users to measure power at the outlet level (RMS, apparent power), providing an accurate view of power consumption at both a server or PDU level.

Alerting

In case a threshold is exceeded, or a circuit breaker trips, the PX alerts the user via e-mail, SMS (via external gateway), audio alarm, and SNMP TRAPs, providing advanced warning before major incidents occur.

Overload Alarm

User-configurable current threshold provides audible and visual alarm on current overload, allowing the user to act immediately to prevent potential burnouts and interruption of services.

Environmental Monitoring

The PX supports external optional but fully integrated temperature and humidity sensors, providing early warning about hotspots or changes in cooling.

Seven-Segment LED Display

Shows actual current, voltage and circuit breaker status of the PDU for both the total strip and for individual receptacles.

Remote Access

IP Auto Configuration with DHCP, BOOTP

Easy setup and administration.

Flexible Remote Access Options

Users can access the PX through a variety of access protocols for switching (where supported), metering, data collection and monitoring:

  • Convenient HTML GUI
  • Server Management Interface (IPMI)
  • Network Management Interface (SNMP)
  • UNIX®-like console interface via serial connector or TELNET/SSH (compatible with SMASH server management)

Dynamic DNS Support

Users can access the PX over a connection with a dynamically assigned IP address - which corresponds to a single DNS name.

IPMI and SMASH CLP

The first and only PDU in the world that supports industry management standards: the Intelligent Platform Management Interface (IPMI) and the Distributed Management Task Force's (DMTF) Systems Management Architecture for Server Hardware (SMASH) CLP, providing a uniform way to manage both servers and the PDU.

Power Management

HTML User Interface

The PX's intuitive browser-based GUI enables remote energy management.

Outlet Grouping

When using PX models which support switching in a stand-alone mode over TCP/IP, users can define multiple outlets across multiple PDUs to function as a single virtual outlet. This is useful for powering down and rebooting servers with redundant power supplies.

Virtual Outlets

For PX models that support switching, outlets on multiple PX units can be grouped for ease of management and administration of servers.

Integration with Multiple Raritan Solutions

Simplified power control capabilities, power on/off/recycle, is available through Raritan's Dominion KXII, Dominion SX, Paragon® II, and CommandCenter® Secure Gateway 3.1.1 or higher, providing systems administrators access to power control via one­user interface.

Security

Up to 256-bit AES Encryption

The PX is the first and only PDU in the industry that supports 256-bit AES encryption.

SSL Certificate

Creating individual server side SSL certificates enhances the security level of PX.

Event Logging

Tracks user logins, logouts, and power activities for an audit trail to support regulatory compliance.

Local and Remote Authentication and Authorization

PX provides built-in support for standards-based authentication protocols, including LDAP/S, RADIUS, and Active Directory. When deployed in conjunction with other Raritan solutions, additional authentication schemes can be supported, including TACACS+, Kerberos, and SecureID.

User-Rights Per Outlet

An administrator can assign permissions on an outlet level to prevent unauthorized access.

Hardware Features

Vertical and Horizontal Rack Mount Models

PX units come in a choice of space-saving form factors for vertical and horizontal rack mounting. 1U and 2U units mount horizontally on standard racks. Zero U units mount vertically on rack frames.

What is Dominion PX (PX)?

The Dominion PX is an intelligent Power Distribution Unit (iPDU) that allows users to reboot remote servers and network devices and monitor power.

It can be used as a stand-alone power distribution unit, or integrated with Raritan’s Power IQ™ energy management software, KVM switches, and CommandCenter® Secure Gateway.

 

Is Raritan new to the power distribution market?
No. On the contrary, Raritan has been in the power distribution unit business since 2003.

 

Can the PX be used as a stand alone device?
Yes, it can be used either as a stand-alone power management unit or it can be integrated with Raritan access and management products.

 

Does PX work with Raritan's CommandCenter® Secure Gateway?
Yes, PX is deployable as part of an enterprise-wide management solution with Raritan's CommandCenter Secure Gateway. Hundreds of PX units can be managed via CommandCenter Secure Gateway directly or through Dominion SX (serial only), KX, and Paragon® II.

 

How can I consolidate the sites where I have a PX installed?
The Raritan Power IQ™ software manages rack PDUs, providing a single Web interface for outlet, rack and data center power, current, voltage, temperature and humidity monitoring and remote outlet switching. Power IQ manages the PX and third-party rack PDUs, and can also be integrated with data warehouse and enterprise reporting systems.

Raritan's CommandCenter Secure Gateway is designed specifically to provide centralized management. It is the ideal solution if you are looking to consolidate management of devices such as PX with other Raritan network-based products. For IP-based consolidation, external Command Line Interface (CLI) scripting, IPMI, and SMASH-CLP may be considered.

 

How does the PX differ from the Raritan Remote Power Control (RPC) unit?
Like RPC, the PX enables remote power cycling of network servers and devices. And like PM, the PX supports remote power monitoring.

However, the PX offers additional features such as outlet-level power monitoring, access via both Ethernet/IP and serial with AES encryption for remote access, an intuitive browser-based GUI, support for optional temperature and humidity sensors and other flexible access methods.

 

Can the firmware on the PX be upgraded?
Yes. The architecture of the PX enables easy firmware upgrades via updates from Raritan.com so you can have the latest functionality without having to buy new hardware.

 

Are updates to PX software free?
Yes. Currently all firmware upgrades are free.

 

Are there any software requirements for PCs connected to PX?
For access using a Web browser, the PX does not require any software to be loaded on the client; however, the browser does have to be Java enabled. When using SSH/TELNET, the customer has to provide an appropriate client. In some operating systems, like Linux®, an SSH client is included in the distribution. Also, OpenSSH.org has an SSH client that can be downloaded free of charge. PuTTY is one of the most popular SSH clients for Windows®, and it can also be downloaded free from the Internet.

 

Will there be other models in the PX family?
Yes. Additional models of the PX family will be available in the future.

 

Can I get custom configurations of the PX?
Yes. Note that lead times will vary depending on the level of customization required.


TOP

In what form factors can I get the PX?
The PX comes in two form factors:
  • Horizontal rack mount – 1U, 2U models
  • Vertical mount – Zero U models

 

In what rack-positions can Zero U models be mounted?
All five mounting positions are supported with the APC racks.

 

Does PX include the 19" rack mount kit or is there an extra charge for this option?
The PX horizontal (rack mount) units come standard with a complete ready-to-install 19" rack mount kit.

 

Does the PX have any fuses?
No. There are no fuses in a PX; instead circuit-breakers are used for branch circuit protection, when required.

 

Why aren't there circuit breakers on PX models that are 20 amps and below?
A 20 amp or less rack PDU (1- or 3-phase) is always connected to a branch circuit that is protected by a 20 amp circuit breaker in a panelboard. This breaker trips when the total of all the outlets in a rack PDU exceeds 20 amps.

North American 208V 3-phase PDUs have the outlets divided into 3 banks. Each bank is wired across two phase legs (L1-L2, L2-L3, L3-L1). NEC requires that if a PDU input is rated greater than 20 amps, then a 2-pole 20 amp circuit breaker must be used to protect each bank of outlets. When each bank draws 20 amps, the total amps on each input line is 35 amps.

In general, we design PDUs using the following rules:

  1. If a PDU is rated less than 20 amps (or 16 amps internationally), then no circuit breakers are used (per UL 60950-1).
  2. If a PDU is rated greater than 20 amps (or greater than 16 amps internationally), then outlets are divided into banks and each bank is over current protected by a 20 amp (or 16 amp) circuit breaker.

 

Some PDUs lose all the power if one or more circuit breakers are tripped. Is this true for PX?
No. In PX PDUs, the control circuitry is in front of all circuit breakers, so tripping any one or more breakers has no affect on power delivered to the controller. In PX 3-phase PDUs, power for the controller is derived from all 3 phases, so even loss of any 2 of 3 phases will not affect power delivered to the controller.

 

What happens to the servers powered by the Dominion PX if the electronics of the PX malfunction? Will the servers lose power?
No. The PX is designed to continue to run with NO change to the power outlets in the case of an electronics malfunction. The outlets that are on will remain on and the outlets that are off will remain off.

 

By factory default are the outlets on a PX enabled (i.e., on) or disabled (i.e., off)?
By factory default all the outlets are enabled – that is to say, they are turned “on.”

 

Why is the LED by each outlet on a PX Green when the outlet is OFF/disabled and RED when it is ON/enabled?
In the world of power, RED indicates that the power is running (outlet is “live” or “hot”) to that outlet. GREEN indicates it is NOT running or that the outlet is not enabled. So the color codes match the expectation of the facilities and IT staff who typically deploy power units in the data center or remote offices. For PX models without switching, all outlets are always enabled.

 

Can I use the Ethernet and the serial ports on the PX at the same time?
Yes. Just ensure that both interfaces are enabled and configured.

 

Can I set the Ethernet port on the PX to run at 100Mbps full-duplex?
Yes.

 

Is the Ethernet port on the PX unit 10/100Mbps auto-sensing?
Yes. But it can also be set to run at 100Mbps.

 

What is the purpose of the RJ12 connector on the front-panel of the PX units?
This feature connector is for adding Raritan's optional but fully integrated environmental monitoring probes.

 

Are environmental sensors available with the PX?
Yes. Optional but fully integrated environmental sensors are available.

 

What are the clicks from the PX circuit breakers tripping?
Clicks from the PX are typically relays opening and closing which is normal. When a circuit breaker (CB) trips, the LED will blink yellow because internal relay boards will not be receiving voltage from the tripped CBs. Also, the CB handle will be physically in the “off” position. Using the LED panel on the PDU to view outlet voltages (press up/down key together to toggle from current readings to voltage readings), the voltages will be zero or near zero if the CBs have tripped.

 

I moved my PX to a new rack and now I can't access it. What happened?
PX ships from the factory with Dynamic Host Configuration Protocol (DHCP) enabled. DHCP is a protocol used by networked devices (clients) to obtain various parameters necessary for the clients to operate in an Internet Protocol (IP) network. DHCP automates the assignment of IP addresses, subnet masks, default gateway and other IP parameters. If a PX is moved to a new location, with DHCP still enabled (the factory default setting), DHCP will again automatically assign the PX an IP address, subnet mask, etc. If the IT administrator tries to access the PX using the IP address assigned at the previous location, the PX will not respond because the PX now has a different IP address. When moving a PX, IT administrators should 1) leave DHCP enabled and then access the serial port of the PX to find the new IP address (see Quick Start Guide), 2) disable DHCP prior to moving the PX so it retains the same IP address or 3) if possible, configure DHCP to assign a specific IP address to the PX.


TOP

Does the PX support outlet-level monitoring?
Yes. Outlet monitoring is supported when using the HTML interface (via the Ethernet port), and via the Command Line Interface (CLI), or IPMI.

 

Where is power measured on PX 3-phase models?
Measuring occurs at four levels: 1) outlet level, 2) phase level, 3) PDU level and 4) circuit breaker level.

 

Can I cluster multiple PXs in a rack or data center using TCP/IP?
Yes. Outlet association is supported on one PX, or multiple Dominion PXs, and any outlet can be associated with any other outlet, e.g., outlet #2 on one PDU and outlet #5 on another PDU. Outlet associations are particularly useful when there are multiple power-feeds to one managed server/device.

Can I use SSH to connect to the PX?
Yes, SSH connections are supported.

 

Does the PX support TELNET?
Yes, PX supports TELNET, but it is disabled by factory default.

 

Why is TELNET disabled by default on the PX?
PX supports enabling of the TELNET daemon. However, because TELNET sends all information “in the clear,” enabling TELNET is at the customer's own discretion. Raritan strongly suggests the use of SSH as a safer alternative to TELNET, since all data is encrypted, including the login sequence.

 

Does the PX support Network Time Protocol (NTP) servers?
Yes. Up to two external NTP servers can be supported by the PX.

 

Does the PX support DNS servers?
Yes. Up to two DNS servers can be supported by the PX.

 

Does the PX support DNS Servers?
Yes. Up to two DNS servers can be supported by the PX.

 

Does the PX support Dynamic DNS?
Yes.

 

Does the PX support a full-featured Command Line Interface (CLI) for advanced applications using external scripting?
Yes. The SMASH CLP­based CLI allows management and configuration of very granular features, like per-outlet IP access control list (ACL).

 

Does PX support SNMP TRAPs, SETs and GETs?
Yes. PX supports SNMP TRAPs, SETs and GETs via an Enterprise MIB. PX supports SNMP v2 and v3.

 

Does PX support syslog?
Yes. PX supports syslog – to primary and secondary servers.

 

Does the PX support SMTP (e-mail) alerts and notification?
Yes.

 

Can an SMTP server that requires a username and password for connection be used for the e-mail notifications from the PX?
Yes. The PX supports SMTP server authentication.

 

Which ports need to be open on the corporate firewall for a secure console session using PX?
Port 443 (for https); optionally, port 80 (http) for user sessions. When using SSH, port 22 needs to be open. For TELNET, Port 23 needs to be open.

 

Can I get the buffered off-line data from the serial port of the PX?
Yes, but only if you use the Dominion SX or other console server that supports this capability.

 

If I am using the Ethernet interface as the primary means of power monitoring and control, does PX support local (direct) port access for “crash-cart” applications in a data center using a terminal (VT100/equivalent)?
Yes, the PX supports local port access. Default parameters are 9600-N-8-1. The local port on the PX is an RJ-45 female. An RJ-45 male to DB9F (female) null-modem cable is provided with each PX for setup and crash-cart applications.

 

How can I restore the PX to factory default setting?
A hardware reset button (recessed pinhole) is provided to allow access to a software (CLI command) mode to restore the unit to factory default. It can also be restored to factory default from the HTML GUI using a Web browser. For safety and security reasons it is not possible to restore the unit to factory default otherwise.

 

TOP

 

What level of encryption does the PX support?
The PX hardware supports up to 256-bit AES encryption.

 

How do I get access to the operating system of the PX?
PX is a secure appliance. Therefore, NO access is possible to the operating system.

 

I have lost my Admin password to the PX. Is there a back door or secret password?
For security reasons, PX does not have any “backdoor” usernames or passwords. Restoring the unit to factory default will reset it to the factory default username and password. There is no back-door password.

 

Does the PX support strong passwords like other Raritan products?
Yes. Full support is provided for strong password options, for example lockout on retries, password length and character control, and a host of other options.

 

Can I use PX over a VPN connection?
Yes, PX fits into most network configurations utilizing TCP/IP. Set up the VPN (typically IPSec) connection, then start the Web browser and enter the URL for the PX unit. The session to the PX runs transparently over the VPN tunnel.

 

Does the PX have a built-in firewall?
Yes.

 

Does the PX support IP Access Control Lists (ACL)?
Yes.

 

Using the CLI, can per outlet IP access control list (ACL) be enabled?
Yes.

 

What Authentication mechanisms does the PX support?
Local database, RADIUS, LDAP/S and Active Directory®.

 

Can the PX support Authorization at a per port level?
Yes. PX can support Authorization at a per port level – via the local database, RADIUS, LDAP/S and Active Directory.

 

When using SSL, does the PX support SSL server certificates?
Yes.

 

Can the PX be used to generate an SSL Client Certificate Request (CSR) for a Certificate Authority (CA)?
Yes.

 

TOP

 

With which release of the Dominion SX can I do full power-control from the HTML GUI?
The Dominion SX release 3.1 fully supports the PX.

 

With which release of CommandCenter Secure Gateway is the PX first supported?
For control via the serial port of the PX, CommandCenter Secure Gateway release 3.1.1 or higher is required.

 

Can I use the SX PowerBoard applet (supported by SX firmware releases through 2.5 only) to control a PX with a SX running 3.0 firmware?
No. The old PowerBoard applet is not compatible with DSX releases 3.0 and newer releases. Upgrade the Dominion SX unit to release 3.1 or higher for support of the PX when the Dominion SX is used in a stand-alone mode to manage the PX. When using the CommandCenter Secure Gateway (CC-SG) with a Dominion SX, CC-SG can be used to provide the On/Off/Recycle commands to the Dominion PX via the Dominion SX.

 

What is the maximum number of PX units controllable through a Dominion SX?
This is limited only by the maximum number of serial ports on a Dominion SX. For example, a 16-port DSX unit can be used to control 16 PX units, and a 32-port DSX can be used to manage 32 PX units. See the PX User Guide for more details on interoperability and maximum units supported by other Dominion series products.

 

Does the KX support the PX?
Yes. See the PX User Guide for more details on interoperability and maximum units supported by other Dominion series products.

 

Is the PX RoHS compliant?
Yes. The PX is RoHS compliant for the European Union (EU), China and Japan.
