2. Connect side A of the serial uninterruptible power supply conversion cable (with the internal threads)
to the vendor-supplied uninterruptible power supply cable.
Figure 7. Serial uninterruptible power supply conversion cable
Note: The IBM System p5 or eServer p5 server local serial ports (tty0 and tty1) and the RJ45 port on the
operator panel do not support uninterruptible power supply communications. The 2-Port
Asynchronous EIA-232 PCI Adapter (feature code 5723) is required as part of the server
configuration to allow serial communications to an uninterruptible power supply. IBM System p5
or eServer p5 servers with logical partitions must use Web/SNMP communications (a card or an
adapter) to attach to an uninterruptible power supply.
