NSTALLATION
Installing, Removing or Replacing a Telephony Card
Important
To comply with the ISED and ACTA regulatory aspects, the label supplied with the telephony card must
be applied on the exterior surface of the EX controller casing during the installation of the telephony card.
Procedure
1.
Make sure an adequate earth ground connection has been made between the grounding screw on
the back of the EX Controller and an appropriate grounding point in your site.
WARNING
:
Adequate earth ground connection of the ex controller is mandatory to avoid any damage
or injuries.
2.
Wear an ESD wrist strap, ensuring that it makes good contact with bare skin.
3.
Attach the ESD wrist strap end to an earth ground (grounding screw on the back of the EX Controller
or unpainted bare metal spot of a grounded equipment rack).
4.
Turn OFF the power switch of the EX Controller.
NOTE
:
Redundant Power Supply units do not have a power switch.
WARNING
:
The controller unit must be turned off before adding, removing or swapping the system
cards.
5.
Turn off the power sources used to power the EX Controller at the circuit breaker.
6.
Disconnect all cables (except the earth ground connection) from the EX Controller.
CAUTION
:
Power source cables must be disconnected last.
7.
Unscrew the two thumb screws of the slot where you wish to install or replace a card.
8.
Gently remove the blank plate or the existing card.
NOTE
:
You can insert any type of card in any of the slots, but you must use the slots from 1 to 8,
without leaving slots empty between two cards. Slot order is indicated on the front of the EX
Controller (left bottom corner).
Important
The only restriction is regarding slot 1:
–
If you have a PRI and a DSP card, the PRI card must be installed in slot 1 and the DSP card
must be installed in slot 2.
–
If you have a PRI card, it must be installed in slot 1.
–
If you have a DSP card, it must be installed in slot 1.
–
If you have no DSP or PRI card, all slots (1 to 8) must remain empty.
NOTE
:
Be aware that if a card is installed and configured to be used in a slot, moving it to
another slot will cause the configuration of the slot to be lost. Therefore the card will no
longer work until it is reconfigured for the new slot.
