HP Netserver High Density Rack Solutions Overview (LP 2000r) HP Power Distribution Options HP offers a series of Power Distribution Units (PDU) for use when the HP Netserver LP 2000r is to be mounted in a rack. The PDUs are especially convenient when mounting multiple servers as you simply route each power cord to the closest PDU rather than to the local power source or the Uninterruptible Power Supply (UPS), if used. In addition to convenience, the HP PDUs also provide protection for the servers.
HP Netserver High Density Rack Solutions Overview (LP 2000r) Because of the varying AC plug and receptacle requirements around the world, the PDUs do not come with attached power cords. Separate cords must be ordered to fit your specific situation. These are the available cords for each PDU: Voltage PDU selected 100-127 VAC E7675A 100-240 VAC 100-240 VAC E7671A E7671A Power Cord Plug Style Length HP Product Number 5-20P 4.5 m (177.2 inches) E7802A C20 4.0 m (157.
HP Netserver High Density Rack Solutions Overview (LP 2000r) Uninterruptible Power Supplies (UPS) The Uninterruptible Power Supply (UPS) is used to provide power to servers and peripherals should the AC power fail. Generally, the UPS will maintain an appropriate level of AC voltage and current long enough for the equipment to save open files and shut itself down in an orderly manner. All UPSs sold by HP for use with the HP Netserver LP 2000r also feature complete surge protection and noise filtering.
HP Netserver High Density Rack Solutions Overview (LP 2000r) All are designed especially for use with the HP Netservers—including their “look and feel.” But they are manufactured and supported by American Power Conversion (APC), supplier of the world’s most reliable power protection, and available exclusively from HP. All the units are rackmountable in a standard EIA 19 inch rack and occupy only 3U of vertical space. The UPSs come complete with all rackmounting hardware.

HP Netserver High Density Rack Solutions Overview (LP 2000r) Installation Ease of installation is one key to speedier deployment. Fortunately, mounting and bringing multiple HP Netservers LP 2000r online is quick with only a few steps to follow. At this point, bring out the power and physical space calculations you made based on the preceding sections and verify that the conditions are still valid.
HP Netserver High Density Rack Solutions Overview (LP 2000r) Marking the rack The HP Netserver LP 2000r rack mount kit requires two EIA units of space in the rack. It is, of course, imperative that all system components be mounted on the level. To ensure this, you must install all the equipment in the correct holes. The instructions below describe how to mark the rack before you begin the installation. Use this section to mark the front and rear columns of the HP System/E or HP System/U rack.
HP Netserver High Density Rack Solutions Overview (LP 2000r) B. 2-post EIA standard non-HP racks (3 options) 1. Fixed, center mounting All mounting hardware brackets are included as standard equipment with the HP Netserver LP 2000r. Only a T-15 Torx driver and a Number 2 Phillips screwdriver are needed for installation. 2. Fixed, flush mounting All mounting hardware brackets are included as standard equipment with the HP Netserver LP 2000r.
HP Netserver High Density Rack Solutions Overview (LP 2000r) 3. Slide mounting Use the HP J1480A, 2-Post Slide Mount Adapter. Attaching the slides is a tool-less procedure. Marking the Rack The HP Netserver LP 2000r rack mount kit requires two EIA units of space in the rack. Use this section to mark the columns of the 2-post non-HP rack. The brackets attach to the front side of the two columns for either flush mount or center mount brackets.
HP Netserver High Density Rack Solutions Overview (LP 2000r) Preparing the HP Netserver for 2-post rack installation Each HP Netserver has two rails attached at the factory and shipped to customers. These two rails must be removed to attach the brackets, before the Netserver can be mounted in the rack. 1. Lay the HP Netserver on a flat surface. 2. Remove the 3 screws holding the rails to each side of the chassis. See figure above. 3.
HP Netserver High Density Rack Solutions Overview (LP 2000r) Installing the Uninterruptible Power Supplies The Uninterruptible Power Supplies (UPSs) are typically the heaviest devices in your installation due to the dense back-up batteries they contain. Therefore, they must be located at the bottom of the rack - or racks.
HP Netserver High Density Rack Solutions Overview (LP 2000r) Cable Management HP System/E racks Once the servers have been mounted in the rack, the next task is to connect the cables. Typically, an HP Netserver LP 2000r will have several of these attached: KVM (keyboard, video and mouse) cables, peripheral (usually SCSI) cables, LAN cables and one or two power cords, since the HP Netserver LP 2000r can be equipped with a second, redundant power supply.
HP Netserver High Density Rack Solutions Overview (LP 2000r) 3 Begin routing the cables. Starting with the server mounted on the bottom of the rack, gather its cables in your hand and curve them towards the right. Tie them with a Velcro™ strap or a cable tie. 4 Secure each cable bundle. Gently guide the cables into the trough of the cable management arm, following the suggestions in the installation instructions.
HP Netserver High Density Rack Solutions Overview (LP 2000r) 6 Route the power cords to the appropriate power distribution unit. Again, different systems require different solutions but servers with redundant power supplies may require special care when selecting the PDUs. To maintain the protection of redundancy, both power supplies in a server can be connected to separate PDUs. In addition you must ensure that your power cords will be long enough to reach the assigned PDU.
HP Netserver High Density Rack Solutions Overview (LP 2000r) Conclusion By providing flexible, tool-less rack solutions, superior cable management, and aids to help plan your rack environment, HP has set the standard for easing rack deployment. By including all the hardware you need with the server, HP insures that you won’t delay your deployment because you forgot to order costly miscellaneous rackmounting accessories.
