Check PSU Module(s)
and Fuse(s). Ensure the
power connector is
unplugged. Remove the
fuse from the rear panel
connector and inspect it.
Has the fuse blown?
Replace the fuse with
one of the correct type
and rating (see Annex B
Technical Specification).
If the PSU still does not
work, unplug the power
cable and call a Service
Engineer.
Possible problem with the
PSU module. Call a
Service Engineer.
6.5.3 Fan(s) Not Working/Overheating
The unit is fitted with four fans, all of which run continuously. Each individual PCB in
the chassis has its own temperature sensor that will highlight if there is a cooling
problem. In the event of overheating problems, refer to Table 6.2.
Note: Failure to ensure a free air-flow around the unit may cause overheating.
This condition is detected by a temperature sensor; it may be used to trigger
an automatic alarm.

Check Fan Rotation.
Inspect the fans located at
the sides of the enclosure.
Are the fans rotating?
Check the temperature
(select Temperature
Alarms on the Device
Info tabbed page).
Check that the EQ8096
has been installed with
sufficient space allowed
for air-flow (see Chapter
2, Installing the
Equipment). If the
ambient air is too hot,
additional cooling may
be required.
Possible break in the DC
supply from the PSU
module to the suspect
fan(s). Call a Service
Engineer.
6.5.4 Hot Swapping a PSU (when Dual PSU option fitted)
The EQ8096 provides a facility to swap out a PSU whilst the unit is still powered.
The EQ8096 supports Compact PCI technology for its PSUs, which offers automatic
load sharing and Hot Swap capabilities.
The following procedure describes the steps required to replace a PSU.
1. Loosen the four PSU locking screws fully.
2. Lever out the faulty PSU by firstly pushing inwards the retaining clips followed by
pulling outwards the two levers.
3. The PSU can now be slid out of its housing.
4. Replace new PSU unit and lock levers in place. Note that levers will make an
audible click when the unit is fully inserted.
