Installing a Flash Memory Card
By default, a Flash memory card (
) containing a valid Cisco IOS XR
software image is inserted in PCMCIA slot 0 before the router is shipped.
PCMCIA slot 0 (SLOT-0) is the bottom slot and slot 1 (Slot-1) is the top slot. Both
Flash memory card slots on each RP can be used at the same time.
The software configuration register is set to 0x0102, which causes the router to
boot automatically from the Cisco IOS XR software image stored on the Flash
memory card.
