Removing a Shelf

This procedure is used to remove a shelf from the database using the dlt-shlf command. If the shelf to be removed does not exist in the database, it cannot be removed. The control shelf (Shelf 1100) cannot be removed from the database. The dlt-shlf command has only one parameter, loc, which is the location of the shelf.

Before a shelf can be removed from the database, all of the cards in that shelf must be removed from the database. The procedures for removing these cards are based on the application that is assigned to these cards. Table 4-3 shows the location of these procedures.

Caution:

If any card in the shelf is the last card of that type in service, removing that card from the database will cause the traffic handled by that card to be lost or the feature requiring that card to be disabled. See Table 4-4 for a description of the effect that removing the last card type that is in service has on the EAGLE.

The shelf being removed in this procedure cannot be removed if the shelf is the only provisioned shelf in the frame and the frame is in the Frame Power Alarm Threshold table. The Frame Power Alarm Threshold table is shown in the rtrv-frm-pwr command output. If the frame is shown in the rtrv-frm-pwr output, and the shelf is the only shelf in the frame, perform the Removing an Entry from the Frame Power Alarm Threshold Table procedure to remove the frame from the Frame Power Alarm Threshold table.

The examples in this procedure are used to remove shelf 2100 from the database.

Display the cards in the database using the rtrv-card command.

This is an example of the possible output.

In this example, these cards must be removed from the database: 2101, 2102, 2103, 2104, 2105, 2106.

Based on the application assigned to the cards in the shelf to be removed, perform the appropriate procedures shown in Table 4-3 and remove all the cards from the shelf.

The application assigned to the card is shown in the APPL field of the rtrv-card command output in step 1.
Display the shelves configured in the database by entering the rtrv-shlf command.
This is an example of the possible output.

If the frame containing the shelf being removed in this procedure is shown in the rtrv-frm-pwr output, the frame must be removed from the frame power alarm threshold table (shown in the rtrv-frm-pwr output) before the shelf can be removed. The following list shows the frames and the shelves contained in those frames.
- Frame CF00 – Shelves 1200 and 1300
- Frame EF00 – Shelves 2100, 2200, and 2300
- Frame EF01 – Shelves 3100, 3200, and 3300
- Frame EF02 – Shelves 4100, 4200, and 4300
- Frame EF03 – Shelves 5100, 5200, and 5300
- Frame EF04 – Shelf 6100
Shelf 1100 is the Control Shelf and is in Frame CF00. Shelf 1100 cannot be removed.

Perform the Removing an Entry from the Frame Power Alarm Threshold Table procedure to remove the frame from the frame power alarm threshold table.

If the frame containing the shelf being removed in this procedure is not shown in the rtrv-frm-pwr output, go to step 5.
Remove the shelf from the database using the dlt-shlf command.
For this example, enter this command.

dlt-shlf:loc=2100

When this command has successfully completed, this message should appear.
```

DLT-SHLF: MASP A - COMPLTD
```
Verify the changes with the rtrv-shlf command and specify the location of the shelf.
For this example, enter this command.

rtrv-shlf:loc=2100

When this command has successfully completed, this message should appear.
```

Back up the new changes using the chg-db:action=backup:dest=fixedcommand.

These messages should appear, the active Maintenance and Administration Subsystem Processor (MASP) appears first.
