Expansion cards can be fitted to any expansion slot.
On the Ascotel IntelliGate 2065, the middle slot (No. 8) is reserved for the MPC-
8260 processor card (Fig. 4.23).
Fitting expansion cards
A Torx screwdriver, size Torx 10, is needed to secure the screening strip (front
cover) to the metal cage.
1. Switch off the PBX: When using a UPS disconnect the battery first, then dis-
connect the PBX and any external Auxiliary Terminal Power Supply (ATPS)
from the 230 V mains.
2. Remove the PBX cover.
3. Before handling an expansion card, touch the earthed metal cage of the PBX.
4. Take the expansion card out of the ESD protective sleeve.
5. Fit the expansion card to the correct slot. Make sure the card is lying in the
lower guide slot of the metal cage and that the ends of the screening strip
(front cover) are flush against the edge of the metal cage once the card has
been inserted.
Note:
The maximum torque for screws used for fitting expansion cards and
dummy covers is 0.9 Nm.
6. Screw the screening strip to the metal cage using the 2 screws supplied.
