Appendix E - When the “Over Temp” Light Comes On 36
Appendix E - When the “Over Temp” Light Comes On
The Intraport Enterprise-8 is designed to operate reliably in a normal computer room, and
requires no special environmental control. If operating within its published temperature and
humidity specifications (0° to 45° C, up to 95% relative humidity, non-condensing, at 40° C)
in a normal computer room, no periodic maintenance is required. If, however, an “Over Temp”
light illuminates, it indicates that the internal circuitry is operating above its specified tempera-
ture range. If this happens, perform the following check sequence:
1. Verify that the server is installed properly in an environment in which the air tempera-
ture around the server is within the specified limits.
2. Verify that air flow to the front of the server is unrestricted.
3. If the above checks do not indicate a problem, it is probable that the air filter inside
the chassis is clogged and must be cleaned or replaced. Follow the procedure outlined
next to clean and replace the dust filter.
Replacing or Cleaning the Intraport Enterprise-8 Air Filter
Under normal operation, the air filter does not require periodic maintenance. The filter should
be replaced only when an excessive amount of dirt and dust has collected over an extended
period of time. A replacement filter is supplied with the unit to minimize the unit’s down time
when the filter is replaced.
Before attempting to change or clean the filter, the unit must be removed from its mounting in
an equipment rack or on a wall. Changing or cleaning the filter is a simple process.
Figure 14. Removing the Filter Cover Plate
1. Remove the filter cover plate by loosening the two captive thumb screws.
2. Remove the filter from its slot.
3. Put the supplied replacement filter in the slot. The used filter may be washed in warm,
soapy water and used again once it is completely dry.
4. Replace the filter cover plate and securely tighten the captive thumb screws.
v Note: If either of the supplied filters is worn out or cannot be thoroughly cleaned, you may
order a replacement filter from Compatible Systems Corporation at the number in the front of
this manual.
