How to Configure Dial Shelves

Step 10 Ensure that split mode is operating properly.
Enter the show dial-shelf command for each router. This command has been extended so that the
response indicates that the router shelf is running in split mode and which slots the router shelf owns.
The status of any cards in any owned slots is shown, just as they are in the present show dial-shelf
command. When in split mode, the output will be extended as in the following example:
System is in split dial shelf mode.

Step 11 Enable all feature boards to accept calls once again.
Changing Slot Sets
You can change the sets of slots owned by the two router shelves while they are in split mode by first
removing slots from the set owned by one router, and then adding them to the slot set of the other router.
The changed slot set information is sent to the respective DSCs, and the DSCs determine which slots
have been removed and which added from the new slot set information. It should be clear that moving a
slot in this manner will disconnect all calls that were going through the card in that slot.
To perform this task, enter the following commands as needed:
When a Slot Is Removed
The router shelf that is losing the slot frees any resources and clears any state associated with the card
in the slot it is relinquishing. The DSC reconfigures its hub to ignore traffic from that slot, and if there
is a card in the slot, it will be reset. This ensures that the card frees up any TDM resource it might be
using and allows it to restart under control of the router shelf that is subsequently configured to own the
slot.
When a Slot Is Added
If there are no configuration conflicts, and there is a card present in the added slot, a dial-shelf OIR
insertion event is sent to the router shelf, which processes the event the same as it always does. The card
in the added slot is reset by the DSC to ensure a clean state, and the card downloads its image from the
router shelf that now owns it.
Command Purpose
Router (config)# dial-shelf split slots remove
slot-numbers
Removes the dial shelf slots listed from the router shelf’s list of
owned dial shelf slots. The effect of multiple commands is
cumulative.
Router(config)# dial-shelf split slots slot-numbers
Adds the dial shelf slots listed to the router shelf’s list of owned
dial shelf slots.
