Uninterruptible power supply

Uninterruptible power supplies are available to meet the power protection needs of IBM® servers. The uninterruptible power supply (UPS) is the IBM type 9910.

The IBM 9910 uninterruptible power supply solutions are compatible with the power requirements for Power Systems™ servers and pass IBM testing procedures. The uninterruptible power supplies are intended to provide a single source for purchase and protection of IBM servers. All 9910 uninterruptible power supplies include a premium warranty package that is designed to enhance the potential for return on investment over the uninterruptible power supplies available on the market today.

Type 9910 uninterruptible power supply solutions are available from Eaton.

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:

The two service processor USB 2.0 ports that are labeled 1 and 2 correspond to location codes Un-P1-C1-T2 and Un-P1-C1-T3. For more information about location codes, see Part locations and location codes.
Feature code (FC) ECCF is available for 5148-21L, 5148-22L,8247-21L, 8247-22L, 8247-42L, 8284-22A, 8286-41A, and 8286-42A systems.
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
