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.
