CAUTIONl Do not apply AC power to the DD9500/DD9800 system controller until allexpansion shelves and cables are installed.l Make sure the PSNT label, attached to the left rear of the chassis is notdamaged or snagged during the installation of the system into the rack.Procedure1. Identify the designated location for the system controller in the rack.l The designated location for a single node, or the primary node of an HA pairwith ES30 shelves is U13-16 in rack 1.l The designated location for the standby node of an HA pair with ES30shelves is U18-21 in rack 1 (single rack) or U13-16 in rack 2 (multiple racks).l The designated location for a single node with DS60 shelves is U23-26 inrack 1.l The designated location for the primary node of an HA pair with DS60shelves is U22-25 in rack 1.l The designated location for the standby node of an HA pair with DS60shelves is U27-30 in rack 1.NoteThe designated slots in the rack are the recommended location for theDD9500/DD9800 system to support the cabling described in this document.Other locations may require different cable lengths for some configurations.2. From the front of the rack, lift the DD9500/DD9800 system using the handlessupplied for lifting to install the system in the rack in the correct location.3. At each side, align the bottom of the chassis with the lip of each installed rackbracket.4. Carefully slide the chassis into the rack and remove the back handles whilesupporting the chassis weight. Continue to slide the rest of the chassis andremove the front handles. Finally, push the chassis all the way into the back ofthe rack.5. The rear of the chassis should engage with the tabs located in the rear of therack mount kit.6. At the front, attach the system to each installed bracket using the screws onthe front of the system. The screws are shown in red circles in the photo.NoteOn each side of the chassis, a bezel bracket sits between the upper and lowerscrews that secure the chassis to the rack. The bezel brackets are marked withleft and right to denote which side of the chassis to install them on. However,the brackets for each side are not physically different. Inverting the bracketallows it to be used on the other side of the chassis.Figure 29 System on a rackInstall the System in the Rack46 Data Domain DD9500 and DD9800 Systems 6.1 Hardware Overview and Installation Guide
