REMOVING AND REINSTALLING THE FAN TRAY
The DLM6C-AA is equipped at the factory with a removable fan tray that
allows for easy periodic cleaning and/or replacement if a problem occurs
with fan operation. A flat blade screwdriver is needed to remove and
reinstall the fan tray. To remove and reinstall the fan tray in the
DLM6C-AA, refer to
Section 3.5.1
and
Section 3.5.2
.
3.5.1
Removing the Fan Tray
To remove the fan tray, refer to
Figure 3-8
and proceed as follows:
1.
Locate the ESD wrist strap shipped with the DLM6C-AA. Attach the
wrist strap to your wrist and plug the cable from the wrist strap into the
ESD grounding receptacle at the upper right corner of the
DLM6C-AA.
2.
Use a screwdriver to loosen the slotted screws located on either side of
the fan tray.
3.
Slowly slide the fan tray out of its slot in the bottom of the chassis.
The HA205-MD sounds an audible alarm if there is a polarity
reversal. If the alarm sounds, turn off the 48/60 Vdc power
source to that power supply. Then reverse the positive and
negative leads to the dc input power strip of that power supply.
Restore power from the 48/60 Vdc power source. If the alarm
sounds again, press the power switch to off, then contact your
DIGITAL representative.
!
The fan tray is hot swappable; however, the chassis must not
be run without the fan tray for extended periods of time, as it
will quickly overheat.
