Emerson PM2003H-401 Rack PDU Firmware 2.1.0.23 Description

This package provides the necessary installation files of Emerson PM2003H-401 Rack PDU Firmware version 2.1.0.23.

Fixes:

- Open SSL upgraded to address the POODLE issue.
- Configuration changes as a result of this release are in the Security Profile menu, Enable HTTPS drop down list:
- SSL version 2 and 3 have been replaced with TLS versions 1.0, 1.1 and 1.2
- Configurations that were HTTPS SSL3 in the previous release will be upgraded to TLS1.2. All other configurations in the previous release that had SSL2 will be upgraded to TLS1.1, TLS1.2 + TLS1.

The previous version (2.1.0.22) shows the maximum current of the PDU for international models. The features and enhancements supported by PDU version 2.1.0.22 include:
- Upgraded Bash to address the Shell Shock issue.

The features and enhancements supported by the previous PDU versions include:

- Extended support for SNMP vendor MIB to include setup of power management parameters:
- PDU chain (pmPowerMgmtSerialTable): enable/disable buzzer, syslog, SW over-current protection; configuring polling rate and power cycle interval.
- PDU table (pmPowerMgmtPDUTable): configuring the PDU ID, setting all levels of current thresholds, resetting its configuration to factory default or rebooting the PDU. Extra information was also included, like alarm status, type of measurement for power, voltage and power-factor, as well as energy info.
- Outlets table (pmPowerMgmtOutletsTable): outlet name, post-on and post-off delays and all levels of current thresholds are configurable. Extra information was also included, like alarm status, type of measurement for power, voltage and power-factor, as well as energy info.
- Phases and banks (pmPowerMgmtPhasesTable and pmPowerMgmtBanksTable): all levels of current thresholds are configurable. Extra information was also included, like alarm status, type of measurement for power, voltage and power-factor.
- Environment sensors (pmPowerMgmtSensorsTable): all levels of thresholds are configurable. Extra information added includes sensors type and alarm status.
- Configuring power management parameters using SNMP are effective upon command completion but they are not saved to Flash, thus not persisted through reboots. A new OID (pmPowerMgmtSerialTableSave) was also introduced to save changes done in the PDUs.
- Depending on the PDU model some of the OIDs may not apply. In such case SNMP queries for those OIDs will return 0 (zero) or “N/A” based on its syntax.
- All new and modified OIDs are defined and detailed in the PDU MIB file.
- Support configuration via BootP request. The BootP Configuration Retrieval option allows the entire unit configuration to be retrieved over BootP / TFTP during boot and during DHCP renewal.
- OpenSSL upgrade
- Apache upgrade from version 2.2.9 to version 2.2.17

To upgrade PM PDU firmware:

1. Download the new PM PDU firmware.
2. Using terminal emulation software, log into the PM PDU as admin and type in the command: pm>upgrade <PDU#>
The <PDU#> is the number of the PDU to which you want to upgrade the firmware. If you have only one PM PDU, type upgrade 1. If you have, for instance, three units in a daisy chain, type upgrade 3 or upgrade 2 depending on which unit you want to upgrade.
NOTE: If you have a daisy chain and you want to upgrade all units, you should start from the last unit and work your way towards the first.
3. At the boot loader menu, select option 1 to upgrade the firmware. The boot loader erases the firmware currently in the unit and asks you to upload the new firmware.
4. Use your terminal emulator program to upload the PM PDU firmware file to the PM PDU using the Xmodem protocol.

About Rack PDU Firmware:

Applying a newer firmware version than the one already installed on your unit can bring various enhancements, include workarounds for diverse problems encountered by the device, and improve or add newly developed features.

On the other hand, downgrading the firmware version can recover the device’s functionality in the event of a software update either turning up faulty or causing the unit’s overall performance to drop. However, bear in mind that applying an older firmware isn’t recommended and might not always be possible.

When it comes to the update steps, due to the large variety of devices and numerous ways for installing a new firmware, it is recommended that you carefully read and understand the upgrade steps, and consider applying a different firmware only when you have familiarized yourself with the update method.

As the installation process is most of the times quite risky, this step should be taken by users that have the ability to successfully complete the update; regular users may initiate it at their own risk. Moreover, it’s best that this task be performed in a steady power environment such as the one ensured by a UPS unit.

Therefore, if you consider applying this release, hit the download button, take into account all the aforementioned aspects, and update the device’s firmware. Also make sure you constantly check with our website to ensure that you don’t miss a single new release. 

  It is highly recommended to always use the most recent driver version available.

Try to set a system restore point before installing a device driver. This will help if you installed an incorrect or mismatched driver. Problems can arise when your hardware device is too old or not supported any longer.
