Installing a Module
The procedure for installing a module in a 3000 Series is basically the same
for all the modules.
To install a module . . .
1. Turn off power to your 3000 Series.
2. Disconnect all network connections, including connections to the
telephone system.
3. Remove the cover by unscrewing the two screws on each side of the unit
and the three screws on the underside of the unit’s chassis and lifting off
the cover.
4. Remove the screws from the standoffs of the slot that you want to use.
5. Remove the module retaining bar by removing the three fastening screws.
6. Place the module in the slot that you want.
Notes:
• You can install the ISDN modules only in slot 3. You can install all
other modules in any of the three configurable slots.
• When you install an ISDN, SDSL, DDS, T1, or E1 module, do not
connect the telephone line until you have installed the module itself.
a. Line up the module with its two screw holes directly over the two
standoffs.
