Performance Route Processor Overview
The performance route processor (PRP) uses a Motorola PowerPC 7450 CPU that
runs at an external bus clock speed of 133 MHz and has an internal clock speed
of 667 MHz.
Figure 1-2 identifies the slots, ports, and LEDs on the PRP front panel.

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 1-2). Each slot has an eject button (located behind the cover)
to remove a flash card from the slot.
