LEDs
Expansion Interface Circuit Pack LEDs
The Expansion Interface (EI) TN570 circuit pack has the standard red, green, and yellow LEDs.
The red and green LEDs have the traditional meaning, where red indicates an alarm condition
and green indicates testing in progress.
The yellow LED displays various flashing patterns to provide status information for isolating
faults in the fiber link and other components connected to the fiber link. Table 73: Expansion
Interface yellow LED flashing codes on page 294 illustrates the EI yellow LED states.

Condition
0.1 sec 0.1 sec Fiber Out-of-Frame. This state indicates a failure of Test #989. This may
be caused by absence of the opposite end EI or Switch Node Interface
(SNI), a broken or missing fiber, or a missing lightwave transceiver on
either endpoint.
0.5 sec 0.5 sec In Frame — No Neighbor. This state corresponds to a failure of Test
#237, usually due to a failure of this EI or of the EI or SNI at the other end
of the fiber.
2 sec 0.2 sec EI Active. This is the normal state of an active EI that is an archangel of
an EPN.
solid on EI Active. This is the normal state for an active EI that is not an EPN
archangel. These include EPN EIs connected to other EPN EIs in direct
connect configurations, and EIs located in the processor port network.
solid off EI Standby. This is the normal state for a standby EI in systems with a
duplication option.
Maintenance Circuit Pack LEDs
TN775D PN maintenance circuit packs have seven LEDs on their front panels. The top three
LEDs are the standard group of red, green, and yellow, and indicate the status of the circuit
pack. The green LED on TN775Ds blinks faintly once per second, indicating continual
self-testing.
