Cisco Systems IGX 8400 Series manual Connecting the Control Terminal

Attaching Peripherals

Attach the control terminal to the SCM. (See Figure 3-16.)

Step 1 From the back of the cabinet, run the control terminal EIA/TIA-232/V.24 cable through the opening at the bottom and up to the SCM card in back slot 1.

Step 2 Locate the Control Terminal connector on the SCM and attach the control terminal EIA/TIA-232/V.24 cable to it.

Step 3 Tighten the EIA/TIA-232 connector screws to firmly attach the cable to the Control Terminal connector.

Step 4 Plug the control terminal power cord into the appropriate wall receptacle.

Step 5 Set the port function for VT100 (#5) using the cnftermfunc command.

Step 6 Make sure the Auxiliary port and the terminal are set to the same baud rate and check the other communication parameters using the cnfterm command.

Note When you power up a node, it enters boot mode. Its control terminal communicates at a default rate of 9600 bps. If the rate for the node’s control port previously was 19,200 bps, the first messages appears garbled because the control port (in boot mode) is temporarily running at

9,600 bps. When the transition to on-line occurs, the speeds match, so the display becomes readable.
