2. Verify HP FC-AL Hub Operation Test the HP FC-AL hub and verify that it operates before mounting it in the cabinet (also called a rack). a. Perform a self-test by connecting the short-wave loopback cable to a short-wave hub port, plugging the power cord into the HP FC-AL hub, and then plugging the power cord into a power receptacle. The short-wave loopback cable includes "50/125" as part of the identification information printed on the cable.The HP FC-AL hub does not have a power switch. If using an A4839A long-wave hub, also self-test the long-wave port with the long-wave loopback cable (A4839-63001). The long-wave loopback cable includes "9/125" as part of the identification information printed on the cable. NOTE The HP FC-AL hub's power supply automatically adjusts to a range of 100 VAC ±10% and 240 VAC ±10%. Interruptions to the HP FC-AL 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 HP FC-AL hub to the circuit. b. The HP FC-AL hub runs the self-test each time the power cord is plugged in or the Reset button is pressed if a loopback cable or a device is connected. c. The HP FC-AL hub finishes the self-test in less than 15 seconds. • If the Fault LED (amber) stays on after self-test, the HP FC-AL hub failed. Contact your sales representative for assistance. • If the Power LED does not light, contact your sales representative. d. Verify the operation of individual ports by inserting the loopback cable into each port and observing that the port status LED lights up. e. Unplug the HP FC-AL hub and continue with the installation procedure. 10

2.
Verify HP FC-AL Hub Operation
Test the HP FC-AL hub and verify that it operates before mounting it in the cabinet (also called a rack).
a.
Perform a self-test by connecting the short-wave loopback cable to a short-wave hub port, plugging the power cord
into the HP FC-AL hub, and then plugging the power cord into a power receptacle. The short-wave loopback cable
includes “50/125” as part of the identification information printed on the cable.The HP FC-AL hub does not have a
power switch.
If using an A4839A long-wave hub, also self-test the long-wave port with the long-wave loopback cable
(A4839-63001). The long-wave loopback cable includes “9/125” as part of the identification information printed on
the cable.
NOTE
The HP FC-AL hub’s power supply automatically adjusts to a range of 100 VAC ±10% and
240 VAC ±10%.
Interruptions to the HP FC-AL 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 HP
FC-AL hub to the circuit.
b.
The HP FC-AL hub runs the self-test each time the power cord is plugged in or the Reset button is pressed if a
loopback cable or a device is connected.
c.
The HP FC-AL hub finishes the self-test in less than 15 seconds.
•
If the Fault LED (amber) stays on after self-test, the HP FC-AL hub failed. Contact your sales representative for
assistance.
•
If the Power LED does not light, contact your sales representative.
d.
Verify the operation of individual ports by inserting the loopback cable into each port and observing that the port
status LED lights up.
e.
Unplug the HP FC-AL hub and continue with the installation procedure.
