Removing and Replacing a Trunk Card
Depending on your configuration requirements, you might need to
replace existing trunk cards or install new trunk cards in your
Cisco 5814 dial shelf. Because the system is designed to recognize
trunk cards only when they are installed in the first six slots, you must
install trunk cards in slots numbered slots 0 through 5 on the dial shelf
backplane.
Note The OIR feature allows you to install and remove a trunk card without
powering off system power. Refer to the section "Online Insertion and
Removal" for a description of OIR.
To remove a trunk card without dropping the calls or connections, you
must first take the trunk card out of service by using the busyout
command to busyout DS0s and modem resources as calls are
completed. The busyout command is executed on a per card (slot)
basis.
The busyout command has the format busyout shelf­number/slot­
number, where shelf number is a user­designated value from 0­9999,
and slot number is 0­5. The following example shows how to busy­out
the card in slot 0 on shelf 5:
r o u t e r # b u s y o u t 5 / 0
r o u t e r #
If you are replacing a failed trunk card, we recommend you proceed as
follows:
1 Busyout the card
2 Remove the existing card
3 Install the new trunk card in the same slot
When replacing a trunk card with a new trunk card of the same type in
the same slot, the system software will recognize the new trunk card
interfaces and bring them up automatically. No additional configuration
is needed. A trunk card installed in any other slot will affect the clocking
source.
Caution
To avoid erroneous failure messages, remove or insert only one trunk card at a
time. Also, after inserting or removing a trunk card, allow at least
15 seconds before removing or inserting another trunk card so that
the system can reinitialize and note the current configuration of all
interfaces.
Note The system brings online only interfaces that match the current
configuration and were previously configured as up; all other interfaces
require that you configure them with the configure command. For
