Server controls, LEDs, and power

This section describes the controls and light-emitting diodes (LEDs) and how to turn
the server on and off.

Front view

The following illustration shows the controls, connectors, and LEDs on the front of
the server. The operator panel on the system-board tray is the same for all server
configurations.

on and off manually or to wake the server from a reduced-power state. The
states of the power-on LED are as follows:
Off: Power is not present or the power supply, or the LED itself has failed.
Flashing rapidly (4 times per second): The server is turned off and is not
ready to be turned on. The power-control button is disabled. This will last
approximately 20 to 40 seconds.
Flashing slowly (once per second): The server is turned off and is ready to
be turned on. You can press the power-control button to turn on the server.
Lit: The server is turned on.
Electrical input:
v Sine-wave input (50 - 60 Hz) required
v Input voltage low range:
– Minimum: 100 V ac
– Maximum: 127 V ac
v Input voltage high range:
– Minimum: 200 V ac
– Maximum: 240 V ac
v Input kilovolt-amperes (kVA),
approximately:
– Minimum: 0.150 kVA
– Maximum: 1.148 kVA
Notes:
1. Power consumption and heat output
vary depending on the number and type
of optional features installed and the
power-management optional features in
use.
2. The noise emission level stated is the
declared (upper limit) sound power
level, in bels, for a random sample of
machines. All measurements are made
in accordance with ISO 7779 and
reported in conformance with ISO 9296.
