11. From the report, is the TG3 circuit pack to be removed in a standby state with
a manual switch?
If YES, then continue with Step 13.
If NO, then continue with Step 12.
12. At the CIT, select FAULT-Switch-Synchronization-Hardware com-
mand for the circuit pack being removed and execute a manual switch. Use
the FAULT-Retrieve-State:TG command to verify, if desired.
NOTE:
A series number S1:2 is the same series number as S1:4. The 2 and 4 refer to
minor changes within series 1.
NOTE:
Power to each shelf must be applied before replacing any circuit packs. For
example, a loss of power to a high speed shelf could show a failure of the
RCVRs in the shelf as the alarm.
NOTE:
An IS-3 circuit pack requires multimode fiber for proper performance monitoring
operation.
13. Obtain a replacement circuit pack with the same or a higher series number
and install it in place of the circuit pack with the lighted FAULT LED. As
required, make the appropriate optical connections on the OC3, IS3, OC12,
RCVR, TRMTR, or REGENR circuit pack(s).
Reference: DLP-514
14. Wait for the time indicated in Table B.
* Inserting an LNCTL circuit pack starts a mini reset that can take up to 10 minutes to complete. During this time,
LEDs on other circuit packs will be lighted.
†When a TG3 circuit pack is first inserted, it will be switched out of service until it warms up. This can take as
long as 5 minutes. You can confirm that it is in the standby state by using the FAULT-Retrieve-State
command for the TG slot.
