Chapter 3: Diagnostics
The grey square indicates the EFC Server cannot communicate with
the switch because:
•
The switch-to-EFC Server Ethernet link failed.
•
Ac power distribution in the switch failed.
•
The control processor (CTP) card failed.
Does a grey square appear at the alert panel and as the background
to the icon representing the switch reporting the problem?
YES
NO
↓
Go to
step 10
.

At the switch reporting the problem, ensure the power switch is set to
the Power On (1) position. Inspect the switch for indications of being
powered on, such as:
•
At the front panel, an illuminated PWR or ERR indicator.
•
Green LEDs illuminated on the power supplies.
•
Audio emanations and airflow from fans.
Does the switch appear powered on?
YES
NO
↓
A power distribution problem is indicated. Go to
step 23
to
obtain event codes. If no event codes are found, go to
MAP
0100: power distribution analysis
on page 218.

Either a switch-to-EFC Server Ethernet link failure or CTP card failure
is indicated. Go to
step 23
to obtain event codes. If no event codes
are found:
a. Fault isolate the least severe failure indicated (Ethernet link
problem). Go to
MAP 0400: loss of console communication
on
page 235.
b. If MAP 400 does not isolate the problem, fault isolate the CTP
card problem. Go to
MAP 0200: POST, reset, or IPL failure
analysis
on page 224.
