Uninterruptible power supply

Uninterruptible power supplies are available to meet the power protection needs of IBM® servers.

For more information about power warning and system shutdown events, or on making changes to the default configuration options such as system shutdown time when a power failure is detected, see:

Feature code ECCF (part number 00FV631) - System Port Converter Cable for UPS

The ECCF is a converter cable that allows for communications from a UPS relay interface card to a service processor USB port. The server has two service processor USB 2.0 ports on the native I/O daughter card that are labeled 1 and 2. Either of these ports (1 or 2) can be used for the ECCF. Only one ECCF is allowed per server. The connectors on the ECCF include a male USB and a female 9-pin D-shell connector. The cable length is 1650 mm (65 inches).

The cable can be connected to either USB port 1 or USB port 2 at any time. It is not necessary to IPL the server for the server to recognize the cable. The cable contains active electronics that tell the service processor that a UPS is attached. The UPS can provide status information (such as UPS on, UPS utility fail, UPS battery low, and UPS bypass) over the cable to the physical hypervisor for broadcast to all partitions.

Notes:
  1. The two service processor USB 2.0 ports that are labeled 1 and 2 correspond to location codes Un-P1-C1-T3 and Un-P1-C1-T4. For more information about location codes, see Part locations and location codes.
  2. Feature code (FC) ECCF is available for select systems.
  3. The pin layout for the 9-pin D-shell connector is as follows:
    • 5 - Signal ground
    • 6 - UPS bypass
    • 7 - UPS battery low
    • 8 - UPS on
    • 9 - UPS utility fail
