IBM System i User Manual

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.
