Step 1: Unpack and Inspect the U9422x/ U9424x Switch Module
ESD
Electrostatic discharge (ESD) can damage or destroy electronic components. All
work on electronic assemblies should be performed at a static- safe work station.
Two types of ESD protection are listed below. Purchase acceptable ESD
accessories from your local supplier.
– Conductive table- mat and wrist- strap combination
– Conductive floor- mat and heel- strap combination
Both types, when used together, provide a significant level of ESD protection. Of
the two, only the table- mat and wrist- strap combination provides adequate ESD
protection when used alone. To ensure user safety, static- safe accessories must
provide at least 1 MΩof isolation from ground.
Inspect for Damage
After unpacking the switch module, carefully inspect it for any shipping damage.
Report any damage to the shipping agent immediately, as such damage is not
covered by the warranty (warranty information can be found at the beginning of
this manual).
CAUTION
The switch module is shipped in a material that prevents it from static
damage. The switch module should only be removed from the packaging in
an anti- static area ensuring t hat correct anti- static precaut ions are taken.
Store the switch module in an anti- static envelope when not in use.
WARNING
These techniques for a static- safe work station should not be used when
working on circuitry with a voltage potential greater than 500 volts.
CAUTION
To avoid damage when handling a switch module, do not touch the exposed
connector pins.

Return for Service
Should it become necessary to return the switch module for repair or service,
follow these steps:
1Review the warranty information shipped with your switch module.
2Contact Keysight to obtain a Return Material Authorization (RMA) and return
address. If you need assistance in finding Keysight contact information, go to
www.keysight.com/ find/ assist (worldwide contact information for repair and
service) or refer to the Support information on the product web page at
www.keysight.com/ find/ USBswitch.
3Write the following information on a tag and attach it to the malfunctioning
switch module.
– Name and address of owner. A P.O. box is not acceptable as a return
address.
– Product model number (for example, U9422A)
– Product serial number (for example, MYXXXXXXXX). The serial number
label is located on the back panel of the switch module. The serial number
can also be viewed from the Soft Front Panel interface, but only after the
software is installed.
– Description of failure or service required
4Carefully pack the switch module in its original ESD bag and packing carton. If
the original carton is not available, use bubble wrap or packing peanuts and
place the switch module in a sealed container and mark the container as
"FRAGILE".
5On the shipping label, write ATTENTION REPAIR DEPARTMENT and the RMA
number.
NOTE
Information on preventing damage to your Keysight equipment can be found at
www.keysight.com/ find/ tips.
NOTE
If any correspondence is required, refer to the product by serial number and
model number.
