How to install control cards
1 Open the door at the front of the frame. The door is hinged on the right-hand side and
swings from left to right. Use the handle on the left-hand side to gently pull the door open.
2 There are two control card guides, as shown in Figure 2-1. Insert each control card horizon-
tally into each set of guides. The cards should slide in easily; do not force them.

3 For each card, press the lever(s) inward, making sure each card is fully seated in its slot.
4 Close the frame door. The door must be closed for the router cooling system to work prop-
erly.
Making System Controller Connections
In order for a SMS7000 system controller and a NV8288, NV8288-Plus or NV8500 Family router to
communicate, the system controller must be connected to an EC9535. The SMS7000 system
controller is connected using the ‘GSC NODE BUS’ connection located on the rear of the EC9535
frame. The connection uses a 75
Ω
BNC connector and coaxial cable.
How to Make SMS7000 System Controller Connections
1 Locate the GSC Node Bus connections on the rear of the router, as shown in Figure 2-2. Sys-
tem controller connections are labeled ‘GSC NODE BUS’.

2 Connect to the ‘GSC NODE BUS’ connection using a 75
Ω
BNC connector and coaxial cable.
Do not drop, roughly handle, or stack circuit boards. If you cannot easily insert or remove a
board, stop and contact Grass Valley Technical Support.
