Step 7
Connect the opposite end of the grounding wire to the appropriate grounding point at your site to ensure an adequate
chassis ground.
Connecting Cables
Keep the following guidelines in mind when connecting any external cable to the Cisco Catalyst 9800-40
Wireless Controller:
• To reduce the chance of interference, avoid crossing high-power lines with any interface cables.
• Verify all the cabling limitations (particularly distance) before powering on the system.
Connecting the Console Port Cable
The controller uses RJ-45 ports for console port to attach a console terminal. The controller has an asynchronous
serial (EIA/TIA-232) RJ-45 console port labeled CON on its front panel. You can connect this port to most
types of video terminals with a console cable kit that is included with your controller. The console cable kit
contains:
• One RJ-45-to-RJ-45 crossover cable
• One RJ-45-to-DB-9 (female) adapter
The crossover cable reverses pin connections from one end to the other. In other words, it connects pin 1 (at
one end) to pin 8 (at the other end), pin 2 to pin 7, pin 3 to pin 6, and so on. You can identify a crossover cable
by comparing the two modular ends of the cable. Hold the cable ends in your hand, side-by-side, with the
tabs at the back. Ensure that the wire connected to the outside (left) pin of the left plug (pin 1) is the same
color as the wire connected to the outside (right) pin of the right plug (pin 8).
The console port is an asynchronous serial port; devices connected to this port must be capable of asynchronous
transmission.
Procedure for Connecting the Console Port Cable
Before you begin
Before connecting to the console interface on the controller using a terminal or PC, perform the following
steps:
Step 1
Before connecting a terminal to the console port, configure the terminal to match the chassis console port as follows:
9600 baud, 8 data bits, no parity, 1 stop bits (9600 8N1).
Step 2
Connect one end of the RJ-45 cable to the serial RJ-45 console port (CON) on the Cisco Catalyst 9800-40 Wireless
Controller using the RJ-45 to DB-9 cable. Connect the DB-9 end to your terminal equipment.
For information about how to change the default settings to meet the requirements of your terminal or host, see
