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.
