1. Prepare the Installation Site

Be sure to follow the guidelines below to ensure proper operation when
installing the switch into a network:
■ Verify that copper and fiber cabling meets the requirements of the
"Cabling and Technology Information Specifications"
Protect the switch from radio frequency interference emissions.
■
■ Use electrical surge suppression.
■ Use safe connections with no damaged cables, connectors, or shields.
Installation Space Requirements
Switch Clearance Requirements
Orientation
Front At least 7.6 cm (3 inches) of space for the twisted-pair and fiber-optic
cabling.
Back At least 3.8 cm (1 1/2 inches) of space for the power cord and switch cooling.
Sides At least 7.6 cm (3 inches) for cooling, except if the switch is installed in an
open EIA/TIA rack.

2. Verify the Switch Passes Self Test

Before mounting the switch, verify it is working properly by plugging it into a
power source and confirming that it passes self test.
1. For the HP 1820 24- and 48-port switches, connect the power cord
supplied with the switch to the power connector on the back of the switch,
and then into a properly grounded electrical outlet.
For the HP 1820 8-port switches, connect the AC/DC adapter's power cord
to the power connector on the back of the switch, and then plug the AC/
DC power adapter into a nearby properly grounded electrical outlet.
