Installing A Software Update
To install a software update, IC U9 or U6 (or both) on the Main Control circuit
card is replaced. If the system consists of multiple BMEs, the software IC(s) in
each BME’s Main Control card may need to be updated. Use the following
procedure to replace the IC(s).
1. Power the system OFF and unplug the AC power cord.
2. Remove the Access Panel (Front Panel if Sync BME). See Page 5-2.
3. Use the PLCC IC puller (Figure 5-3.A) to remove the existing Software IC.
Squeeze the tool to align the hooks with the slots provided in opposite
corners of IC socket U9 or U6. Insert the hooks, squeeze gently and pull
the IC straight out of the socket. Set the IC aside.
4. Note the key (angled corner) of the new Software IC. Orient this to match
the key of the socket and carefully press it in place.
5. Reinstall the Access Panel (Front Panel if Sync BME).
6. Plug in the AC power cord, power the system ON.
7. Verify that the switcher is working properly.
