In this table, a black box indicates an orange LED, a gray box indicates a green LED, and an empty box indicates an unlit LED.
† The Port Number LED for each port, when lit, shows its port number on its interface card. Unless otherwise specified, the Port
Number and Net Fail LEDs appear as shown for all ports on the interface card.

Interpreting LED Error Patterns

If a failure occurs when power to the router is cycled (switched off and
on), refer to table 3-1 below for information about using LED patterns to
diagnose the failure. If a failure occurs during router operation, refer to
table 3-2 (page 3-6).
In tables 3-1 and 3-2, a black box indicates an orange LED, a gray box
indicates a green LED, and an empty box indicates an unlit LED.
Some of the diagnostic tips in tables 3-1 and 3-2 refer you to entries in
the event log (which can be displayed from the Main menu) and the
crash history (which can be displayed using NCL's Crash command). To
display either the event log or the crash history, you must have a console
connected to the router before you switch the router on, with the PC or
terminal set to 9600 baud.
If an LED error pattern according to table 3-1 or 3-2 seems to indicate a
failure but the router nevertheless appears to be operating correctly,
refer to "Verifying LED Operation," page 3-9.
For most interface cards, the 3rd, 7th, 11th, and 15th LEDs are used to
indicate the Port Number, and the 6th, 10th, 14th, and 18th LEDs are
used to indicate Net Fail—as shown in this table. If a particular interface
card uses these LEDs differently, its documentation describes that use.
