Installing an LS2020 Switch in Rack

Step 5 Inspect all external surfaces of the chassis for signs of damage. Pay special attention to areas of the chassis corresponding to visible damage to the shipping container.

Step 6 Document any damage noted during the inspection.

Step 7 Contact your LS2020 vendor if your LS2020 switch has been damaged during shipment.

This section explains how to mount an LS2020 chassis in an equipment rack.

Note For physical stability, when an LS2020 chassis is installed in a rack, the equipment conﬁguration should comply with UL Standard 1950, Par. 4.1.1, and IEC 950, 4.1.1.

Cooling Air and Hardware Placement

An LS2020 chassis takes in cooling air at the bottom of the front panel and exhausts it at the top rear and right side of the chassis. (The air vents on the right side of the chassis can safely be covered by the rack side panels, but they should not otherwise be blocked.) To minimize the potential for thermal problems, position the LS2020 chassis so that

The air intake panel is not located near the exhaust of other equipment.

The exhaust is not located near the air intake of other equipment.

Required Tools

Ensure that you have the following items on hand before you begin installing the LS2020 switch:

•A number 2 Phillips screwdriver for mounting the chassis.

•A 5/16-inch slotted-tip screwdriver for removing blowers, power supplies, and boards from the chassis.

•An ESD wrist strap for grounding yourself to the chassis.

•Antistatic shielding bags or antistatic mats for protecting components removed from the chassis.

•Appropriate material-handling equipment for lifting the LS2020 switch into the rack.

•For AC-powered systems: an LS2020 Country Power Kit, which includes a power cord and mounting hardware for the chassis.

•For DC-powered systems: a DC Mounting Kit, which contains mounting hardware for the chassis, plus equipment needed by the electrician for wiring the system (see the subsection entitled “Preparation for Wiring” later in this chapter).

Rack Installation Procedure

To mount the LS2020 switch in an equipment rack, perform the following steps:

Step 1 Ensure that the power cord to the system is disconnected before you begin with the installation.

Step 2 Put on the ESD wrist strap and connect it to a grounding jack on the front or the rear panel of the LS2020 chassis.
