Connecting the UPS (Uninterruptible Power Supply)
1. If you do not have an UPS (Uninterruptible Power Supply) located in the rack,
install it before attempting to connect it to the Netserver.
2. Connect the serial cable provided between the UPS and the HP Netserver.
Refer to the user guide included with the UPS for additional information
and ensure you configure the Netserver's serial/management port correctly
in Setup (BIOS) Utility.
NOTE The HP Netserver's serial/management port must be configured
correctly or the UPS and Netserver may not work correctly.
3. If you have connected the serial cable between the two devices, turn on the
UPS.
The HP Netserver LP 1000r performs a diagnostic test when the power
switch is turned on. If an error condition occurs, note any error code
appearing on the display, then refer to Chapter 12, "Troubleshooting."
