Caution To prevent system problems or loss of data, use the soft reset switch only at the advice of Cisco service personnel.

PCMCIA Slots

The GRP has two PCMCIA slots available. Either slot can support a Flash memory card or an input/output (I/O) device as long as the device requires only +5 VDC. The GRP supports Type 1 and Type 2 devices; it does not support +3.3 VDC PCMCIA devices. Each PCMCIA slot has an ejector button for ejecting a PCMCIA card from the slot.

Asynchronous Serial Ports

Two asynchronous serial ports are provided on the GRP faceplate—a console port and an auxiliary port. These ports enable you to connect external devices that you can use to monitor and manage the system.

•Console port—The console port is an Electronics Industries Association/ Telecommunications Industry Association (EIA/TIA)-232 female receptacle that provides a data circuit-terminating equipment (DCE) interface for connecting a console terminal.

•Auxiliary port—The auxiliary port is an EIA/TIA-232 male plug that provides a data terminal equipment (DTE) interface. This auxiliary port supports flow control and is often used to connect a modem, a channel service unit (CSU), or other optional equipment for Telnet management.

Ethernet Port

The GRP has one Ethernet port that you can access using either of the following connection types:

•RJ-45 receptacle: an 8-pin, media dependent interface (MDI) that supports an IEEE 802.3 10BaseT (10 Mbps) or an IEEE 802.3u 100BaseTX (100 Mbps) Ethernet connection.

•MII receptacle: a 40-pin, media independent interface (MII) that provides additional flexibility for making Ethernet connections. The pinout of this standard 40-pin receptacle is defined by the IEEE 802.3u standard.
