8 Port Ethernet Smart Switch With Fibre Uplink

Trouble Shooting

Power

1.Verify that the AC power is present and that the external fusing is correct and compliant with national requirements. The green Power LED should be lit to indicate that the switch is powered correctly.

Data Problems

1.Ensure that the Ethernet partner device (switch, router, NIC etc) connected to the RJ-45 UTP port of the switch is set for auto- negotiation. If this Ethernet partner device does not support auto-negotiation, then you need to program that device to operate at 100Mbit/s half duplex or 10Mbit/s half duplex or program this switch using the console port.

2.If the switch and the partner device cannot auto-negotiate then both units automatically revert to the lower level of half-duplex operation. This issue is common to all auto-negotiating Ethernet devices and the symptoms of incorrect negotiation include data errors and fragmented packets.

3.Auto-negotiation can take up to 30 seconds to complete depending on the partner device.

4.Ensure that the switch is not overheating due to obstructed airflow around the side vents.

5.Select the proper fibre cable for your network. See page 4 for the supported cable types and installation settings.

6.Ensure that the optical loss budget of the fibre uplink is within the limits specified on page 11. Note that optical patch cables and other joints and splices can introduce additional optical losses that reduce the working distance of the fibre link.

7.Restore factory settings by selecting option 3 on the main menu of the console port.

Console Problems

1.Verify that the PC has been set up with the correct serial link settings as detailed on page 7.

2.Ensure that the serial data cable supplied with the switch is used.
