ProCurve Switch fl Redundant Power Supply

Installing a Power Supply

This section explains how to install a power supply in a Switch 8100fl chassis.

Note If you are also installing Switch fl modules, it is recommended that you

complete installation of the modules before turning on the power to verify the

installation. For information on how to install the modules, refer to either the

ProCurve Switch 8100fl Series: Installation and Getting Started Guide or

the ProCurve Switch 8100fl Series: Switch fl Module Installation Guide.

Before You Start

Before you install a power supply in a Switch 8108fl or Switch 8116fl, be sure

to follow these preliminary steps and cautions:

Installation ■ Make sure that the power source circuits are properly grounded, then

use the power cord supplied with the power supply to connect it to

and

the power source. Use a single-phase grounded power source located

within 6 feet (1.89 meters) of the installation site.

■ If your installation requires a different power cord than the one

supplied with the power supply, be sure to use a power cord

displaying the mark of the safety agency that defines the regulations

for power cords in your country. The mark is your assurance that the

power cord can be used safely with the power supply.

■ High leakage current can be caused by multiple power supplies. For

this reason, it is essential that each power cord be connected to

separate branch circuits with proper earth connections.

■ Ensure that the power supply does not overload the power circuits,

wiring, and over-current protection. To determine the possibility of

overloading the supply circuits, add together the ampere ratings of all

devices installed on the same circuit as the switch with this power

supply and compare the total with the rating limit for the circuit. The

maximum ampere ratings are usually printed on the devices near the

AC power connectors.

■ Do not install the power supply into a switch that is in an environment

where the operating ambient temperature might exceed 40°C (104°F).

Note that although the power supply can operate in temperatures up

to 55°C (131°F), 40°C is the maximum operating temperature for the

switch.
