Installation and Configuration

Initial inspection

When you receive your U8903B, inspect the unit for any obvious damage such as broken
terminals or cracks, dents, and scratches on the chassis that may occur during shipment. If
any damage is found, notify the nearest Keysight Sales Office immediately.
Keep the original packaging in case the U8903B has to be returned to Keysight in the
future. If you return the U8903B for service, attach a tag identifying the owner and model
number. Also, include a brief description of the problem.

Ventilation

The U8903B can operate within the temperature range of 0 °C to 55 °C. The U8903B is
cooled by drawing air through the sides and bottom at the front of the U8903B, and
exhausting it through the ventilation holes on the sides and top at the rear of the U8903B.
The U8903B must be installed in a location that allows sufficient space at the top, sides,
and rear for adequate air circulation.

Rack mounting

The U8903B can be mounted in a standard 19-inch rack. Rackmount kits are available as
Option 908. Support rails are also required for rack mounting. These are normally supplied
with the rack and are not included with the rackmount options.
If you are installing an instrument on top of the U8903B, ensure that the instrument does
not obstruct the ventilation holes at the top of the U8903B. If required, use a filler panel
above the U8903B to ensure adequate space for air circulation.
