Inserting Modules to Previously Empty Slots

The procedure below describes how to add additional modules (i.e., digital, and FXS and
FXO analog) to previously empty module slots in the gateway.
Warning:
Note:
To install a module to a previously empty slot, take these 6 steps:
Power off the Mediant 1000.
1.
On the Mediant 1000 front panel, using a Phillips screwdriver remove the black metal
2.
cover plate protecting the module slot.
Insert the module into the empty slot, with the plain side of the Printed Circuit Board
3.
(PCB) facing up. Make sure the PCB slides into the slot rails by aligning the module
with the rails in the slot.
Push the module into the slot and press on it firmly to ensure it has been fully inserted.

Replacing the Air Filter

The fan tray module includes a removable air filter (located within the fan assembly,
immediately inside the perforated grill). The air filter should be replaced approximately
every 90 days and should be checked weekly to ensure it is not saturated and that it does
not require cleaning / replacement. You should clean the air filter no more than three times,
after which the air filter should be replaced.
The air filter removed from the fan tray unit is shown in
Cleaning or replacing the air filter can be carried out while the system is fully functioning.
Warnings:
Version 5.0
Adding a module to a previously empty slot must only be
performed when the power to the gateway is switched off.
The standard FXO module supports outdoor and indoor (lightning
protection) loop start signaling. For ground start signaling, the FXO G
module is required. This module supports either loop or ground start, and
only supports indoor protection. (The FXS module supports both loop and
ground start signaling.)
To enable ground start, use the ini file parameter GroundKeyDetection
(refer to Section 6.5.2
•
When removing the fan tray unit, the fans continue rotating at a high
speeds. Use caution not to touch the rotating fan blades.
•
Prepare all the equipment you need to clean the air filter before
removing it for cleaning. It is imperative that the chassis does not
remain without the fan tray unit for a long period of time. Be sure to
reinsert the fan tray unit while you are cleaning the air filter and
reinsert the air filter as soon as it is clean.
