Chapter 4 Troubleshooting the Installation

Troubleshooting the Processor Subsystem

PRP-3 is the route processor for the Cisco XR 12404 and 12804 Router chassis

running Cisco IOS XR Software Release 3.8.0 or a later release. The PRP-3 is

available as product number PRP-3 or PRP-3= for a primary route processor and

is available as PRP-3/R for a redundant route processor. PRP-3 has significant

improvements over PRP-2. These improvements include increased speed,

improved scalability, higher system memory, faster packet processing. Because

PRP-3 does not support Cisco IOS, the bootflash memory no longer exists in

PRP-3. PRP-3 ROMMON has software intelligence to download a Cisco IOS XR

image without the support of bootflash memory.

Note PRP-3 supports Cisco XR 12410 (10 G per slot fabric) and Cisco XR 12810 (40

G per slot fabric) Router chassis only. PRP-3 does not support Cisco XR 12004,

12006, 12010, and 12016 Router chassis (2.5 G low-speed fabric).

PRP PCMCIA Card Slots and Status LEDs

Two PCMCIA card slots (slot 0 and slot 1) provide the PRP with additional flash

memory capacity. All combinations of different flash devices are supported by the

PRP. You can use ATA flash disks, Type 1 or Type 2 linear flash memory cards,

or a combination of the two.

Note The PRP only supports +5.2 VDC flash memory devices. It does not support

+3.3 VDC PCMCIA devices.

Status LEDs (Slot-0/Slot-1) indicate when the flash memory card in that slot is

accessed (see

Figure 4-3). Each slot has an eject button (located behind the cover)

to remove a flash card from the slot.
