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.
