Before cleaning the switch, unplug all power cords from the switch. Do not clean the switch with wet
cloth or liquid.
Do not place the switch near water or in a damp environment. Prevent water or moisture from entering
the switch chassis.
Do not place the switch on an unstable case or desk. The switch might be severely damaged in case of

Ensure proper ventilation of the equipment room and keep the air inlet and outlet vents of the switch free
of obstruction.
Connect the yellow-green protection grounding cable before power-on.
Make sure that the operating voltage is in the required range.

just powered off.
When replacing FRUs, including power supplies and fan trays, wear an ESD-preventive wrist strap to
avoid damaging the units.
Examining the installation site
The HP 5900AF-48XG-4QSFP+ switch must be used indoors.
Mount your switch in a rack and make sure:
Adequate clearance is reserved at the air inlet and exhaust vents for ventilation.
The rack has a good ventilation system.
Identify the hot aisle and cold aisle at the installation site, and make sure that ambient air flows into the
switch from the cold aisle and exhausts to the hot aisle.
Identify the airflow designs of neighboring devices, and prevent hot air flowing out of the bottom device
from entering the top device.
The rack is sturdy enough to support the switch and its accessories.
The rack is well earthed.
To ensure normal operation and a long service life of your switch, install it in an environment that meets the
requirements described in the following subsections.
