Chapter 3 Connecting the Cisco ONS 15530
Connecting the CPU Switch Module
Connecting a Terminal to the Console Port
The Cisco ONS 15530 CPU switch module 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 terminals through use of
the console cable kit that is included with your Cisco ONS 15530. The console cable kit contains:
• One RJ-45 to RJ-45 crossover cable
• One RJ-45 to DB-25 (female) adapter
• One RJ-45 to DB-9 (female) adapter
A 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).
