Installation Procedure 3: Verify Hub Operation By performing this procedure, you test the hub and verify that it operates properly before you mount it in a rack or connect any devices to it. 1. To initialize the self-test, first plug the power cord into the hub and then into a power receptacle. The hub does not have a power switch. The hub runs the self-test each time the power cord is plugged in or the Reset button is pressed. Note The hub's power supply automatically adjusts to a range of 100 VAC ±10% or 240 VAC ±10%. 2. The hub finishes the self-test in less than 15 seconds. If the Fault LED (amber) stays on after self-test, the hub failed. Refer to chapter 4, Troubleshooting, or contact an HP service representative for assistance. If the Power LED does not light, refer to chapter 4, Troubleshooting, or contact an HP service representative. Note Interruptions to the hub's AC power source initiate a self-test. Make sure the power source circuits are properly grounded before using the supplied power cord to connect the hub to the circuit. 3. Verify that each Fibre Channel port is operating properly. Insert the loopback cable into the port and verify that the port status LED turns on. Both ends of the loopback cable plug into the port connectors. If you plan to use Fibre Channel Manager to manage the hub, continue with step 4. If you do not plan to use Fibre Channel Manager or another hub management tool, go to step 7.

Installation
Procedure 3: Verify Hub Operation
By performing this procedure, you test the hub and verify that it operates properly before
you mount it in a rack or connect any devices to it.
1.
To initialize the self-test, first plug the power cord into the hub and then into a power
receptacle. The hub does not have a power switch.
The hub runs the self-test each time the power cord is plugged in or the Reset button is
pressed.
Note
The hub’s power supply automatically adjusts to a range of 100 VAC ±10% or
240 VAC ±10%.
2.
The hub finishes the self-test in less than 15 seconds.
If the Fault LED (amber) stays on after self-test, the hub failed. Refer to chapter 4,
Troubleshooting, or contact an HP service representative for assistance.
If the Power LED does not light, refer to chapter 4, Troubleshooting, or contact an HP
service representative.
Note
Interruptions to the hub’s AC power source initiate a self-test. Make sure the
power source circuits are properly grounded before using the supplied power
cord to connect the hub to the circuit.
3.
Verify that each Fibre Channel port is operating properly. Insert the loopback cable into
the port and verify that the port status LED turns on. Both ends of the loopback cable
plug into the port connectors.
If you plan to use Fibre Channel Manager to manage the hub, continue with step 4. If you
do not plan to use Fibre Channel Manager or another hub management tool, go to step 7.
