5.1.1Hardware Troubleshooting

No LEDs on

•Check the host platform to see if it is powered up.

•Check that the HSIM-W87 has been connected correctly, that the connectors have no bent pins.

Link (LNK) LED is OFF

The WAN interface is not conﬁgured for operation. Power is off or the HSIM-W87 is not connected properly.

Link (LNK) LED is RED — The WAN interface is conﬁgured, but there is no signal indicating that a valid connection is present on the WAN interface.

•Check that the device at the other end of the segment is powered up.

•Use management to make sure that both WAN interfaces, local and remote, are conﬁgured correctly.

•Check to ensure that the correct cable is being used.

•Check to ensure that the cable has continuity and is installed correctly. The cabling between the HSIM-W87 and the M13 should be checked, and the cabling between the M13 and the devices at the far end should also be checked.

•Check with the WAN Service Provider to ensure that the circuit has been conﬁgured by them and is active.
