3-2.) If your cable came from Cisco, pin 1 will be white on one connector, and pin 8 will be white on the other (a rollover cable reverses pins 1 and 8, 2 and 7, 3 and 6, and 4 and 5).
Configure your terminal or terminal emulation software for 9600 baud, 8 data bits, no parity, and 2 stop Step 2 bits. Because hardware flow control is not possible on the console port, Cisco does not recommend Note that modems be connected to the console port. Modems should always be connected to the auxiliary port.
Connecting the Fixed FE Interface Cables The RJ-45 port supports standard straight-through and crossover Category 5 unshielded twisted-pair (UTP) cables (refer to Figure 3-15). Cisco Systems does not supply Category 5 UTP cables; these cables are available commercially. Step 1 Confirm that the router is turned off.
Connect one end of the cable to the T1 or E1 port on the card. Step 2 Connect the other end to the BTS patch or demarcation panel at your site. Step 3 Cisco MWR 1941-DC Mobile Wireless Edge Router Hardware Installation Guide 78-15827-06B0...
