326 S8100 Installation and Upgrades
November 2003
If the circuit pack has just been inserted, the system may still be initializing the circuit pack. If,
after 5 minutes, the circuit pack still has not initialized communications with the system, check
the MO for any special instructions. If the MO does not provide the needed information, perform
the following steps:
1 Check the Error Log for TONE-BD and TDM-BUS errors. Follow appropriate sections
for any TONE-BD and TDM-BUS errors.
2 Reseat the suspected circuit pack.
!
WARNING:
Reseating a TN2314 can be very destructive. This should be done only if its green Complete
Shutdown LED is lit. Otherwise, you must shut down before reseating.
3 Wait 5 minutes. Then issue the list configuration board PCSS command. If the result
indicates that the system still has not registered the circuit pack, go to next step.
4 If the system seems to be functioning correctly, but the circuit pack does not start
communicating with the system, replace the circuit pack.
• Green (test) – the system is running tests on this circuit pack.
• Yellow (busy) – indicates that the circuit pack is in use.
NOTE:
A port circuit pack also lights its red LED when it performs initialization tests (for
example, when the circuit pack is initially inserted into the system). If every initialization
test passes, the red LED is turned off. If not, the red LED remains lighted and the circuit
pack is not placed into service.
During the various states of operation (start-up testing, normal operation, circuit failure, and so
forth) circuit pack status LED indications appear as shown in Table 54, Control and port circuit
pack status LEDs, on page 326.
Table 54: Control and port circuit pack status LEDs
Equipment type LED Description
Port circuit packs Red Briefly on during a power up, a circuit pack’s reseating or
resetting, or system reset. Steadily on if a circuit pack fails start-
up test or fails while in use. Off during normal operation.
Green Briefly on during a circuit pack’s testing following power up, a
circuit pack’s reseating, or a system reset. On during periodic,
scheduled, or a technician’s on-demand testing. Off during
normal operation.
Yellow On when any of a circuit pack’s ports are in use (otherwise, off).
