Access to the soft reset switch is through a small opening in the PRP faceplate. To press the
switch, you must insert a paper clip or similar small pointed object into the opening.
Flash Disk Slots
The PRP includes two Flash disk (PCMCIA) slots. Either slot can support an ATA Flash
disk or a Type 1 or Type 2 linear Flash memory card. The PRP ships by default with one
64-MB ATA Flash disk.
Note The PRP only supports +5VDC Flash disk devices. It does not support +3.3VDC
PCMCIA devices.
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. Each
Flash disk slot has an ejector button for ejecting a card from the slot.
Note Type 1 and Type 2 linear Flash memory cards may not have the capacity to meet the
requirements of your configuration.
Asynchronous Serial Ports
The PRP has two asynchronous serial ports, the console and auxiliary ports. These allow
you to connect external serial devices to monitor and manage the system. Both ports use
RJ-45 receptacles.
The console port provides a data circuit-terminating equipment (DCE) interface for
connecting a console terminal. The auxiliary port provides a data terminal equipment
(DTE) interface and supports flow control. It is often used to connect a modem, a channel
service unit (CSU), or other optional equipment for Telnet management.
Ethernet Ports
The PRP includes two Ethernet ports, both using an 8-pin RJ-45 receptacle for either IEEE
802.3 10BASE-T (10 Mbps) or IEEE 802.3u 100BASE-TX (100 Mbps) connections.
