Steps for Mounting an Array in a Rack

Tomountanarrayinarack,followthesesteps:

1. Determinewheretoplacethemountingrailsintherack.

2. Attachthemountingrailstotherack.

3. Slidethechassisintotherack.

4. Attachthechassistothefrontofthemountingrails.

5. Installthebezel.

Thesestepsaredescribedindetailinthefollowingsections.

Determine Where to Place the Mounting Rails in the

Rack

Makesurethereisenoughspaceintherackforthechassis.Inastandardrack,a2Uchassis

Installing the Rails and Array in a Rack

Installtherailsintherackfollowingthesafetyinstructionsandtherackinstallationinstructions

providedwithyourrailkit.

Ifinstalledinaclosedormulti-unitrackassembly,theoperatingtemperatureoftherack
