| Determining Whether a Switch is Faulty |
|
| If you suspect that a HyperFabric switch is faulty, follow the steps below to determine if |
|
| the switch needs replacing. |
|
| HF1 Switch |
|
| The steps for determining if an HF1 switch is faulty are as follows: |
Step | 1. | Disconnect the cable from the switch port you suspect is faulty. |
Step | 2. | Attach a copper loopback plug to the relevant port. A copper loopback plug is shipped |
|
| with each HF1 adapter (not with the HF1 switch). |
Step | 3. | Determine if the port is faulty: |
•If the port is functioning correctly, the port’s LED shows as solid or blinking green.
•If the port is faulty, the port’s LED is off.
Repeat Steps 1 through 3 for all ports on the switch, to determine if any of them are faulty.
Step 4. If any one of the ports on the switch is faulty, do not use it. Use a known good port if one is available. If no good ports are available, you must replace the switch. (See “Replacing a HyperFabric Switch” on page 126.)
HF2 Switch
The steps for determining if an HF2 switch is faulty are as follows:
Step 1. Check the cards/switch module in the
a.If the card/switch module is functioning correctly, its “Operating/Fault” LED shows as solid green.
b.If the card/switch module is experiencing a fault, its “Operating/Fault” LED shows as solid yellow.
c.If the card/switch module is not operating, its “Operating/Fault” LED is off.
Step 2. Check the switch’s power:
a.If the power to the switch is on, the “Power A” and “Power B” LEDs both show as solid green.
b.If only one of the “Power” LEDs shows as solid green, the switch is still operational. However, the integrated Ethernet management LAN adapter card should be replaced soon. (Remember, it can be replaced by qualified
c.If both “Power” LEDs are off, the enclosure (the power supply, backplane, and
Step 3. Check the switch’s Ethernet ports:
