Manually Initiating a Line Card Switch
Line cards are installed in the half-height slots at the rear of the chassis. This design allows for two line cards (both
Ethernet 10/100 both Ethernet 1000 (or both QGLCs on an ASR 5000)) to be installed behind every application card.
When two line cards are installed, as the application card that they are installed behind is booted, the card in the upper-
rear chassis slot will automatically be made active while the card in the lower-rear chassis slot will automatically be
placed in standby mode. In the event that the active card experiences a failure, the system will automatically switch
traffic to the standby card in the lower slot.

In the event that an issue arises that is not severe enough for the system to perform an automatic switch, a manual switch
can be performed. Follow the instructions below to manually initiate a line card or SPIO switch. These instructions
