SHOCK HAZARD — NEVER open the power supply. There are
no field serviceable components inside. Capacitors inside the
power supply case present a shock hazard even with the power
switched off and the power cord removed.
LOSS OF MONITORING/FUNCTION — It is important to
identify the defective power supply before turning off and
removing it. If you turn off/remove the wrong power supply, the
ApexPro Telemetry Server will shut down and the ApexPro
system will stop functioning.

BURN HAZARD — Do not touch the power modules with your
bare hands. The power module covers act as heat sinks to aid
cooling, and are typically at 50°C to 60°C (122°F to 140°F) when
the ApexPro Telemetry Server is in operation. Severe burns could
result.
The ApexPro Telemetry Server is equipped with "Hot swappable" power modules.
This feature allows for power module replacement with no interruption in ApexPro
Telemetry Server operation.
1. If you are removing a defective power module, determine which power module
is defective. The LED over the power switch on the defective module will not
be illuminated.
2. Put on heat-resistant gloves, and keep them on for the remainder of this
procedure.
3. Turn off the power switch on the left side of the power module back panel.
