To connect the switch to the console using Mini-USB Type-B console port:
1. Connect the Standard-A connector of the mini-USB cable to the host machine (PC
or Laptop).
2. Connect the Mini-USB Type-B (5-pin) connector of the mini-USB cable tothe Mini-USB
Type-B console port (labeled CON) on the switch.
3. Set the Mini-USB Type-B console port as the active consoleport by using the command

Connecting a Fiber-Optic Cable to a Switch
EX Series and OCX1100 switches support optical transceivers, which are field-replaceable
units (FRUs). You can connect fiber-optic cables to these transceivers.
Before you begin connecting a fiber-optic cable to an optical transceiver installed in a
switch, ensure that you have taken the necessary precautions for safe handling of lasers
(see “Laser and LED Safety Guidelines and Warnings for Switches” on page 273).
To connect a fiber-optic cable to an optical transceiver installed in a switch:
WARNING: Do not look directly into a fiber-optic transceiver or into the ends
of fiber-optic cables. Fiber-optic transceivers and fiber-optic cables connected
to transceivers emit laser light that can damage your eyes.
1. If the fiber-optic cable connector is covered with a rubber safety cap, remove the cap.
Save the cap.
2. Remove the rubber safety cap from the optical transceiver. Save the cap.
3. Insert the cable connector into the optical transceiver (see Figure 52 on page 175).
