Cisco Systems GRP-B manual Connecting MII or RJ-45 Cables to GRP Vertical Orientation

Replacing a GRP

•MII connections—Attach an MII cable directly to the MII receptacle on the GRP or attach a 100BASET transceiver with the media appropriate to your application to the MII port on the GRP. (See Figure 10.) Be sure to use the appropriate strain relief on cable connections.

•RJ-45 connections—Attach the Category 5 UTP cable directly to the RJ-45 receptacle on the GRP. (See Figure 10.)

The Ethernet interface on the GRP is an end station device, not a repeater; therefore, you must connect the Ethernet interface to a repeater or hub.

Caution To prevent problems on your system and network, do not simultaneously connect RJ-45 and MII cables to a single GRP Ethernet interface. On a single GRP, only one Ethernet connection can be used at a time. Only connect cables that comply with EIA/TIA-568 standards. (Refer to Table 6 and Table 7 for cable recommendations and specifications.)

Caution An Ethernet port is used primarily as a Telnet port into the Cisco 12000 Series Router, or for booting or accessing Cisco IOS software images over a network to which an Ethernet port is directly connected. Cisco Express Forwarding (CEF) functions are switched off by default for security reasons. Cisco strongly cautions you to consider the security implications of switching on CEF routing functions on these ports.

Figure 11 shows an example of the functionality of the Ethernet port. In this example, you cannot access Network 2.0.0.0 via the Ethernet port (E0) on the GRP in Router A; you can only access the hosts and Router C, which are in Network 1.0.0.0. (See dotted arrows in Figure 11.)

To access Network 2.0.0.0 from Router A, you must use an interface port on one of your line cards (in this example, a Packet-over-SONET (POS) line card in Router A) to go through Router B, through Router C, and into Network 2.0.0.0. (See solid arrows in Figure 11.)
