Fan Tray Module
The V6100 components are cooled by a fan tray unit located to the extreme right, when
facing the front panel (see
Figure 7 ).
The fan tray unit draws air in by six fans through a perforated grill at the right side of the
chassis. The incoming air passes through a removable filter, whose honeycombed design
prevents RF interference. The clean air passes through the entire set of modules cooling
each one and exits the V6100 via perforated vents on the left side of the chassis.
Blank panels are used to cover all unoccupied slots on the front and rear sides of the
chassis. The blank panels are especially constructed to assist optimal air flow within the
chassis.
It is imperative to cover all unoccupied slots in the front and rear panels of the chassis with
blank panels to maintain internal airflow pressure.

Replacing the Air Filter
The fan try 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 require cleaning /
replacement. You should clean the air filter no more than three times, after which the air filter
requires replacement.
The air filter removed from the fan try unit is shown in Table 16 .
Cleaning or replacing the air filter can be carried out while the system is fully functioning.
To clean / replace the air filter:
1
Release the two screws on the top right-hand corner and the bottom right-hand corner of
the front panel of the fan tray unit.
2 Pull the fan tray unit outward. Figure 8 shows the fan try unit slightly extracted.
