Cisco 7500 SERIES ROUTE SWITCH PROCESSOR 16 Specification Guide

To disable the Cisco 7500 Single Line Card Reload feature, enter the no service
single-slot-reload-enable global configuration command on the Cisco 7500 series router.

Use the show running-config command to verify that single line card reloading has been successfully
enabled on the Cisco 7500 series router. If the service single-slot-reload-enable line appears in the
command output, Cisco 7500 SLCR is enabled. If this line does not appear in the command output, Cisco
7500 SLCR is disabled.

In the following example, SLCR is enabled for all lines cards in the Cisco 7500 series router:

Router(config)# service single-slot-reload-enable

In the following example, SLCR is disabled for all line cards in the Cisco 7500 series router:

Router(config)# no service single-slot-reload-enable

The debug oir command is used to debug the online insertion and removal (OIR) feature (which is also
known as hot-swapping or power-on servicing). The debug oir command is often useful in debugging
problems related to OIR, including single line card reloading.
