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 1-11 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 1-11). Each slot has an eject button (located behind the

cover) to remove a flash card from the slot.
