1. Plug the power cord into the hub’s power socket and into an ac power source. Note that

the hub does not have a power switch; the hub is powered on when the power cord is

plugged in.

The HP Fiber-Optic Hub Plus has a power supply that automatically adjusts to any ac

power source that provides between 90 and 240 volts. No voltage range setting is

necessary.

2. Check the LEDs on the hub’s back panel.

When you plug in the hub, it executes a self-test and illuminates all the LEDs for

approximately ten seconds. At the end of the self-test you should see the following

LED pattern:

– The Power LED is ON.

– The Fault LED is OFF.

– Disregard the other LEDs until you have attached the LAN segments to the network

ports.

If the LED pattern is different, refer to “Diagnosing With the LEDs” in chapter 4,

“Troubleshooting”.

2. Plug in the hub and verify its operation
