Bip Alarm Led Board - Nortel Passport 15000 Hardware Description

Minor indicates that a non-service-affecting hardware or software failure has
occurred. Corrective action must be taken to prevent a minor fault from
escalating into a more serious problem. These are examples.
• A fan or its controller has failed. A minor, as well as a major, frame-level
alarm is generated.
• A shelf temperature is higher than 72 degrees Celsius (161.2 degrees
Fahrenheit).
• The BIP alarm module has failed.

BIP alarm LED board

The BIP alarm LED board connects to the alarm backplane. The alarm LED
board indicates
• shelf failure
• BIP failure
If a fault occurs in either of the nodes connected to the BIP, an alarm is
generated. If physical maintenance at the frame site is necessary, the network
operator can alert a craftsperson to help clear the alarm. The LED indications
on the alarm module assist the craftsperson in locating the correct frame.
LEDs on the alarm module and the cages then direct the craftsperson to the
part that caused the alarm.
The network operator can supply the craftsperson with this information:
• the location and part responsible for the fault
• a list of possible pieces of equipment at fault
The craftsperson can then use this information with the lit LEDs on the spot
to determine which part to replace.
Amber follow-me lights are located on the BIP. A frame indicator light (aisle
light), provided by the customer, can be connected to the alarm system. The
following lights are designed to guide the technician to the system that
generated the alarm:
• "Aisle indicator" (page 68)
