Upgrading to a 300 or 450 MHz Controller
If you have a 133 MHz controller, you can replace it with a 300 MHz
controller. You can replace a 700-User 300 MHz controller with 450 MHz
controller. 64 compression channels requires a minimum 300 MHz
controller.
To upgrade a 133 MHz controller to a 300 or 450 MHz controller:
1. Power down the old controller (see page 99).
2. Disconnect all cables from the old controller.
3. Move the hard drive from the old controller to the new controller (see
“Hard Drive Replacement Overview” on page 125).
4. Remove each controller’s cover (see page 99).
5. Move the System ID module from the old controller to the new
controller (see “System ID Module” on page 133).
6. Connect the cables to the new controller.
7. Power up the new controller.
WARNING:TO UPGRADE TO A 300 OR 450 MHZ CONTROLLER,
MOVE THE HARD DRIVE FROM THE OLD CONTROLLER TO
THE NEW CONTROLLER. MANUALLY INSTALL THE RELEASE
