Installing the second power supply
module (AC or DC)
Introduction
One power supply module is shipped installed. The second power supply
module is shipped uninstalled and must be installed as part of the CallPilot
installation.
AC versus DC systems
The power supply modules are similar in appearance for both AC and DC
1001rp servers. The procedures in this section apply to both AC and DC
1001rp servers.
About the power supply module
After the server is powered up (later in this guide), the power supply module
LED indicates its status.
A green LED indicates that the power supply module is working properly. If
the LED on the power supply module is unlit or red, the module is failing or
has failed. Other indicators are an alarm sounding and the power supply
LED on the status display on the front of the server turning red.
