Expansion Interface LEDs
The EI circuit pack has the standard red, green, and amber LEDs. The red and green LEDs
have the traditional uses: red means some alarm condition and green indicates maintenance
testing in progress. The amber LED provides useful visual status information. The state of the
amber LED is very important when executing the Expansion Interface Manual Loopback
Procedure. The possible amber LED states are shown in Table 204: Expansion Interface
Circuit Pack Amber LED Flashing States.
Upon power-up, the red and green LEDs turn on and off. The amber LED goes to its appropriate
state.
To determine which PNC (and which EIs in a PN) is active and which is standby, use status
port-network and status pnc. Alternately, visual inspection will show that the active EI
circuit packs will have their amber LED on solid (for an inter-PN EI in a direct connect system)
or blink a pattern of 2 seconds on and 200 ms off. The standby PNC EI circuit packs will have
their amber LEDs off. See Table 204: Expansion Interface Circuit Pack Amber LED Flashing
States for the possible EI amber LED states.
Table 204: Expansion Interface Circuit Pack Amber LED Flashing States
Condition LED On LED Off
Fiber Out-of-Frame (a) 0.1 second 0.1 second
In frame-No Neighbor (b) 0.5 second 0.5 second
Expansion Interface Active (c) 2 second 0.2 second
Expansion Interface Active (d) solid on never off
Expansion Interface Standby (e) never on solid off
Notes:
a. Fiber Out-of-Frame - This flashing state corresponds to error codes 769 and 770 from the
Hardware Error Log and indicates a failure of Test #238. These error codes will usually be
accompanied by error code 1281 (no Expansion Interface or SNI detected on opposite end
of fiber). This condition may be caused by the absence of the neighbor EI or SNI circuit
pack, a broken or missing fiber, or a missing lightwave transceiver on either endpoint (EI or
SNI circuit pack).
b. In frame-No Neighbor - This flashing state corresponds to error code 1281 from the
Hardware Error Log and indicates a failure of Expansion Interface Neighbor Query Test
(#237). This condition is usually due to the failure of this EI circuit pack or a failed EI or SNI
circuit pack neighbor.
c. This is the normal state for an active PN EI circuit pack that is also the bus master
(Expansion Archangel) in the PN.
