Chapter 2 Alarm Troubleshooting

Alarm Procedures

2.6.118 LPBKTERMINAL (G-Series)

Not Alarmed (NA), Non-Service Affecting (NSA)

A G-Series Loopback Terminal condition occurs when a software terminal loopback is active for a port on the reporting card.

When a port in terminal loopback, its outgoing signal is redirected into the receive direction on the same port, and the externally received signal is ignored. On the G1000-2 card, the outgoing signal is not transmitted; it is only redirected in the receive direction. G1000-2 cards only support terminal loopbacks.

For more information about loopbacks, see the “Network Troubleshooting Tests” section on page 1-2.

Procedure: Clear the LPBKTERMINAL (G-Series) Condition

Step 1 Complete the “Clear a Loopback” procedure on page 2-128.

Step 2 If the condition does not clear, log onto http://www.cisco.com/tac for more information or call TAC (1-800-553-2447).

2.6.119 MAN-REQ

Not Alarmed (NA), Non-Service Affecting (NSA)

The Manual Switch Request on a Facility/Equipment (MAN-REQ) condition occurs when a user initiates a manual switch request on an OC-N card or UPSR path. Clearing the manual switch clears the MAN-REQ condition.

Procedure: Clear the MAN-REQ Condition

Step 1 Complete the “Clear a UPSR Lock Out” procedure on page 2-127.

Step 2 If the condition does not clear, log onto http://www.cisco.com/tac for more information or call TAC (1-800-553-2447).

2.6.120 MANRESET

Not Alarmed (NA), Non-Service Affecting (NSA)

AUser-Initiated Manual Reset (MANRESET) condition occurs when you right-click a card in CTC and choose Reset. Resets performed during a software upgrade also prompt the condition. The MANRESET condition clears automatically when the card finishes resetting.

Note MANRESET is an informational condition. It does not require troubleshooting.
