Verifying LED Operation

Verifying LED Operation
If you suspect a non-operating LED—for example, if the LEDs indicate a
failure as shown in table 3-1 or table 3-2, or they have some anomalous
pattern (for example, off or red); but the router nevertheless appears to
be operating correctly—you can verify the LEDs by resetting the router
using the following procedure.
C a u t i o n
Resetting the router causes bridging and routing tables to be reset. For
other effects, see "Initialization Sequence" on page 2-15.
Press and hold the Reset button, and verify that while you are holding it,
all of the router status, module status, and port status LEDs are lit. Also,
for each interface card, verify that the Swap LED is lit and that the
colors of the port status LEDs match those shown in table 3-3
(page 3-10).
If any of the router status, module status, and port status LEDs is not lit,
or if any LED that table 3-3 indicates should be orange appears green or
red instead, the router must be replaced.
If a Swap LED is not lit, you can use the card, but it should not be hot
swapped: if you need to replace the card, you should use the procedure
"Replacing the Routing Engine or an Interface Card (System Offline)"
(page 3-27) rather than the procedure "Replacing an Interface Card
(System Online)."
