Replacing a GRP

Connecting to the Auxiliary Port

The auxiliary port on the GRP is an EIA/TIA-232 DTE, DB-25 plug for connecting a modem or other DCE device (such as a CSU/DSU or another router) to the router. The port is labeled Auxiliary. An example of a modem connection is shown in Figure 5. The asynchronous auxiliary port supports hardware flow control and modem control. Table 3 lists the pinout for this port.

Table 3	Auxiliary Port Pinout

Auxiliary Port Pin		Signal	Direction	Description

2		TxD	—>	Transmit Data (to DCE)

3		RxD	<—	Receive Data (from DCE)

4		RTS	—>	Request To Send (used for hardware flow control)

5		CTS	<—	Clear To Send (used for hardware flow control)

6		DSR	<—	Data Set Ready

7		GND	–	Signal Ground

8		CD	<—	Carrier Detect (used for modem control)

20		DTR	—>	Data Terminal Ready (used for modem control only)

Connecting to the Ethernet Port

Information you need to make connections to the Ethernet port on your GRP is presented in the following sections:

•Ethernet Interface Receptacles, Cables, and Pinouts

•Ethernet Interface Cable Connection Procedure

Ethernet Interface Receptacles, Cables, and Pinouts

The two Ethernet interface receptacles on the GRP are a single media independent interface (MII),

40-pin, D-shell type receptacle, and a single RJ-45 receptacle. The RJ-45 receptacle provides a media dependent interface (MDI) Ethernet port. You can use either one or the other, but not both at the same time.

Each connection supports IEEE 802.3 and IEEE 802.3u interfaces compliant with the 10BASE-T and 100BASE-TX standards. The transmission speed of the Ethernet port is auto-sensing and is determined by the network to which the Ethernet interface is connected; transmission speed is not user configurable.

RJ-45 Connections

Figure 6 shows the GRP RJ-45 receptacle and cable connectors. The RJ-45 connection does not require an external transceiver. The RJ-45 connection requires Category 5 unshielded twisted-pair (UTP) cables, which are not available from Cisco Systems, but are available from commercial cable vendors. Table 4 lists the pinout for the RJ-45 receptacle.
