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).
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.
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 1-9). Each slot has an eject button (located behind the cover)
to remove a flash card from the slot.
PRP-3 does not have PCMCIA slots (slot 0 and slot 1). PRP-3 has an external
CompactFlash (disk0:) that replaces the PCMCIA slots.
The PRP has two 8-pin media-dependent interface (MDI) RJ-45 ports for either
IEEE 802.3 10BASE-T (10 Mbps) or IEEE 802.3u 100BASE-TX (100 Mbps)
Ethernet connections. These ports are labeled ETH 0 and ETH 1.
The transmission speed of the Ethernet port is not user-configurable. You set the
speed through an autosensing scheme on the PRP which is determined by the
network that the Ethernet port is connected to. However, even at an autosensed
data transmission rate of 100 Mbps, the Ethernet port can only provide a usable
bandwidth of substantially less than 100 Mbps. You can expect a maximum usable
bandwidth of approximately 20 Mbps when using an Ethernet connection.
The following LEDs on the front panel indicate traffic status and port selection
