How to Configure Dial Shelves
DC-119
Cisco IOS Dial Technologies Configuration Guide
To configure a router for split dial shelf operation, perform the following steps:
Step 1 Ensure that both DSCs and both router shelves are running the same Cisco IOS image.
Note Having the same version of Cisco IOS running on both DSCs and both router shelves is not
mandatory; however, it is a good idea. There is no automatic checking that the versions are
the same.
Step 2 Schedule a time when the Cisco AS5800 can be taken out of service without unnecessarily terminating
calls in progress. The entire procedure for transitioning from normal mode to split mode should require
approximately one hour if all the hardware is already installed.
Step 3 Busy out all feature boards and wait for your customers to log off.
Step 4 Reconfigure the existing router shelf to operate in split mode.
Step 5 Enter the dial-shelf split slots command, specifying the slot numbers that are to be owned by the existing
router shelf.
Step 6 Configure the new router shelf to operate in split mode on other feature boards.
Step 7 Enter the dial-shelf split slots command, specifying the slot numbers that are to be owned by the new
router shelf. Do not specify any of the slot numbers that you specified in Step 6. The range of valid slot
numbers is 0 through 11.
To perform this step, enter the following command in global configuration mode:
Step 8 Install the second DSC, if it has not already been installed.
Step 9 Connect the DSIP cable from the second DSC to the new router shelf.
Command Purpose
Router(config)# dial-shelf split slots
slot-numbers
Enter list of slot numbers, for example:
dial-shelf split slots 0 1 2 6 7 8
In this example, the other router shelf could be configured to own the
other slots: 3 4 5 9 10 11.
Normal mode: This command changes the router shelf to split mode
with ownership of the slots listed.
In case of conflicting slot assignments, the command is rejected and
a warning message is issued. Issue a show dial-shelf split slots
command to the other router shelf to display its list of owned dial
shelf slots.
Online insertion and removal (OIR) events on all slots are detected
by both DSCs and added to the list of feature boards physically
present in the dial shelf; however, OIR event processing is done only
for assigned slots.
Split mode: This command adds the dial shelf slots listed to the
router shelf’s list of owned dial shelf slots.
