Cisco Systems Cisco 12008 manual Flash Disk Slots, Ethernet Ports

Overview of the Cisco 12008

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.
