About the power supply module
After you power up the server (later in this guide), the power supply module
LED indicates its status.
A green LED on each power supply module indicates that the modules are
working properly. If the LEDs are unlit or red, the module is failing or has
failed. A problem with a power supply module is also indicated if the PWR
or MJR LED on the front of the server turns red.
Rack power and grounding
To ensure a complete power and grounding installation:
• In rack-mount server installations, ensure the CallPilot server chassis
and equipment racks are isolated from other foreign sources of ground.
Acceptable isolation methods include: isolation pads, grommeted
washers, chassis side-rail strips, and nonconducting washers.
• In rack-mount server installations where other equipment is also
installed in the same rack, ensure that all equipment derives ground
from the same service panel as CallPilot and the switch.
Connecting the server to power
Before you begin
Ensure that proper power and grounding are available for all the power
outlets serving the CallPilot server and its associated peripherals. Power
for these devices must be wired and fused independently of all other
receptacles, and referenced to the same ground as the PBX system.
A qualified electrician must implement the single-point ground reference as
required between the power outlets of the CallPilot server and the power
outlets of the switch.
