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 +5 VDC Flash disk devices. It does not support
+3.3 VDC PCMCIA devices.
The PRP supports different combinations of Flash devices. 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.
Ethernet Ports
The PRP has two 10/100 Mbps Ethernet ports, each 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. (See Figure 1-8.)
Note The transmission speed of the Ethernet ports is auto-sensing by default and is user
configurable.
Asynchronous Serial Ports
The PRP has two asynchronous serial ports, the console and auxiliary ports.
(See Figure 1-8.) These ports 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.
