HP LH6000r HP Netserver LH 3000 Rack Cabling Guide - Page 14

Chapter 1 Preparation for Cabling the HP NetServer LH 3000r NOTE Older racks (with the words "HP Systems" on the nameplate) may require that enclosures to be tied together before any components are mounted inside them. To avoid problems, if older rack versions are to be tied together, do so before installing slide members, rails, shelves, units, or other hardware. Otherwise, you may have to remove components from the rack to gain access to the tie-bolt locations. 2. If present, remove the front and rear doors to increase accessibility inside the rack. Follow instructions shipped with the rack to do so. NOTE Older racks (with the words "HP Systems" on the nameplate) may also require door hardware to be in place before mounting components. If you are using front or rear doors on older models of the HP Systems Rack, be sure the hinge and latch hardware is mounted before putting on any other hardware. This prevents later disassembly. WARNING When the back door of a rack is removed, the hinge and latch catch brackets protrude. To avoid injury, temporarily remove these brackets prior to installing components into the rear of the rack. 3. If present, remove side panels to allow better access. Follow instructions included with the rack to do so. 8. Install Fans If Required and Redundant Switch and UPS First If You Have Them 1. If an extractor fan unit is to be used, install it following instructions which accompany the unit. NOTE Most HP NetServers have an internal fan system. However, rack doors must be perforated (front and rear). In this case, you do not need an extractor fan. 2. If an Uninterruptible Power Supply (UPS) is used, install the UPS mounting rails and fasten the unit in place following instructions which accompany it. Place the UPS equipment in the lowest EIA Units of the rack. Plug the UPS in to charge the batteries as soon as possible. 10
