Action
The router can have a Switching and Forwarding Module (SFM) in each of the slots
labeled
SFM 0
and
SFM 1
at the rear of the chassis, as shown in “M40e Chassis Description”
on page 8. To maintain the SFMs, regularly:
•
Check the LEDs on the SFM faceplates. The green LED labeled
OK
lights steadily on
the active SFM when it is functioning normally. No LEDs are lit on the standby SFM.
For more information, see “M40e SFM LEDs” on page 23.
•
Issue the CLI
show chassis sfm
command to check the status of the SFMs. As shown
in the sample output, when two SFMs are installed the active SFM is marked as
Online
,
and the standby SFM as
Online - Standby
:

Action
To verify that the power system is functioning normally, regularly:
•
Check the LEDs on the faceplate of both power supplies:
•
An AC power supply is functioning correctly when the green LED labeled

is lit steadily.
•
A DC power supply is functioning correctly when the green LED labeled
CB ON
is lit
steadily (indicating that the circuit breaker is switched on) and the blue LED labeled
OUTPUT OK
is lit steadily (indicating that the supply is receiving power from the DC
source).
