3Carefully remove the transceiver interface module from its shipping container.

4Slowly insert the module into the slot, being careful not to damage any of the components or connecting pins.

The module will slide into the hub following the tracks in the slot. The lettering that shows the module type must be positioned on top of the connector openings when the module is in place.

5Push the module all the way in until the connector is firmly seated.

6Tighten the two thumbscrews to secure the module in place.

7Reattach the power cord to the hub.

8Attach the proper cable to the module to make the desired network connection.

The ACTIVITY LED for the thirteenth port on the hub’s front panel should be green, indicating the module is correctly installed.

use the 3Com Redundant Power System (RPS) (part number 3C565047).

Power System

The RPS must be purchased separately.

 

The RPS, which is rack-mountable, comprises two load-sharing bulk power

 

supplies fed by two independent AC lines. Either power supply alone can

 

support a stack of up to four hubs. Eight hubs in a stack will require two RPS

 

units, one mounted on the bottom of the stack and the other on the top.

 

Redundant fans protect against possible failures caused by overheating.

 

The RPS front panel provides LED indicators for monitoring temperature as

 

well as input and output status. In the event of a failure in one of the

 

supplies, an alert is automatically sent to the management console.
