Inserting Modules into Previously Empty Slots
The procedure below describes how to add additional I/O modules to previously empty slots
in the device's chassis.
Warning:
Ensure that you power down the device before adding a module to a
previously empty slot.
¾
To install a module into a previously empty slot:
1.
Power off the device.
2.
On the device's front panel, using a Phillips screwdriver, remove the black metal cover
plate protecting the module slot.
3.
Insert the required module into the empty slot, aligning the module with the rails in the
slot in the following module orientation depending on whether you are inserting it in the
top- or bottom-row slots:
•
Top-row slots:
ensure that the module is orientated such that the port number
labels are located at the bottom of the module's front panel. This module
orientation is considered as facing up.
•
Bottom-row slots:
ensure that the module is orientated such that the port
number labels are located at the top of the module's front panel. This module
orientation is considered as facing down.
4.
Push the module into the slot and press on it firmly to ensure it has been fully inserted.
5.
Using a flathead screwdriver, tighten the module's mounting pins.
6.
Power on the device.
2.5.4
Replacing the Air Filter
The Fan Tray module includes six integrated fans, which cool the device's internal
components. The Fan Tray module draws in air through a perforated grill on the right side
of the chassis. The incoming air passes through an air filter, whose honeycombed design
prevents radio frequency (RF) interference. The filtered air passes through the entire set of
modules, cooling each one, and then exits the device through perforated vents on the left
side of the chassis.
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 three months and should be checked weekly to ensure that 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. Cleaning or replacing the air filter
can be carried out while the system is fully functioning.
