Figure 6 – QAM24 Board installed in Chassis
The QAM24 board plugs into the Ethernet Card slot and therefore replaces that card. There are
no card guides in the chassis; the board is retained by front panel screws, which MUST be
installed.
Install the QAM24 Board as follows:
1. Remove power from the chassis. Remember to unplug BOTH power cables.
2. Remove the chassis top cover to gain access to the slot connector and rear panel GbE port
cable.
3. Unplug the rear panel Ethernet cable
4. Remove the switch access board.
5. Install the QAM24.
6. Tighten front panel retaining screws.
7. Plug power cables back into the chassis.
A front view of the QAM24 can be seen in Figure 7.
