Chapter 1 Preparation for Cabling the HP NetServer LH 3000r standby mode. Inrush current is much greater than the server’s normal operating needs. Generally, your external AC power source can handle the inrush current. However, if you install several HP NetServers on one circuit, precautions are necessary. For instance, if there is a power failure and power is then restored all the servers immediately begin to draw inrush current at the same time.
Chapter 1 Preparation for Cabling the HP NetServer LH 3000r Prevent Electrical Shock WARNING Ensure site electrical circuits have reliable earth grounding. Never operate products in any rack enclosure with the ground connector disconnected. Although leakage current from any one device may be minimal, cumulative leakage current of equipment mounted in a rack may exceed 5mA, and could reach 15mA. This level of current can be dangerous, unless a reliable earth ground is in place.
Chapter 1 Preparation for Cabling the HP NetServer LH 3000r Generic Rack Assembly Steps Suggested Method for Building an HP NetServer Rack Installation 1.
Chapter 1 Preparation for Cabling the HP NetServer LH 3000r 3. Prepare Rack Enclosures for Assembly WARNING A tip-over hazard exists. Rack enclosures are shipped upright and are top-heavy. Never move enclosures without adequate equipment and assistance. Use caution to prevent rack from falling over and causing potential damage or injury. If you receive pre-configured units, follow assembly instructions from the supplying organization first, if you have them.
Chapter 1 Preparation for Cabling the HP NetServer LH 3000r WARNING When equipment is mounted on slides, a tip-over hazard exists. Always take the precautions listed below: • Extend or bolt on the anti-tip foot for each rack before mounting equipment on slides. • Never extend more than one piece of slide-mounted equipment at a time. • Reduce weight by removing power supplies. • Always use the rack mounting handles that are shipped on rack optimized units as shown in accompanying instructions. 4.
Chapter 1 NOTE Preparation for Cabling the HP NetServer LH 3000r 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.
Chapter 1 Preparation for Cabling the HP NetServer LH 3000r 3. Install the Redundant Switch, if you have one, in one of the configurations shown in Appendix B. 9. Mount Component in the Rack Plan Component Locations Use the original ordering information to locate where each component goes in the rack. If the original ordering information is not available, use HP rack configuration tools to plan the location of each component.
Chapter 1 Preparation for Cabling the HP NetServer LH 3000r NOTE For both safety and accessibility, always start assembly at the bottom of the rack and work upward. 4. Be sure to locate and place rack nuts along the front outside face of the vertical column before placing each component on its rails or base. The pre-positioning of rack nuts allows the front of the component to be secured to the front of the rack.
Chapter 1 Preparation for Cabling the HP NetServer LH 3000r • Determine configurations for and mount the PDU (Power Distribution Unit or Units). Connect the LH 3000r Data Cables to Peripheral Components • Plan where data connections are to be made. • Attach data cables to the server. Mark the ends of data cables with colored tie-wraps and labels supplied with each server. This simplifies attaching cables later in the procedure.

Chapter 2 Rack Cabling References Data Cabling References and Guidelines A series of positioning rules is used in the HP rack configuration tools to help determine where each component is placed in multiple rack layouts. Key Cabling Guidelines Used in Developing a Rack Layout The following discussion is intended to support your understanding of how your rack order was arrived at. It also discusses how rack layouts affect the attachment and routing of cables.
Chapter 2 Rack Cabling References • Ensure the monitor cables and mouse cables are long enough to allow the NetServer to be extended at the same time the keyboard tray is pulled out. Use locally available extensions if necessary. • The mounting distances provided in rack configuration tools assume cables between the servers and connected devices provide for the Cable Management Arm (for the LH 3000r).
3 Procedure for Connecting and Routing Cables to the LH 3000r Step 1: Prepare to Cable the HP NetServer LH 3000r Assess How Components Will be Connected to the Server You may find the following steps to be helpful before you begin cabling: • Review the layout of the rack installation generated with Hewlett-Packard rack configuration tools, such as Rack Assistant (available at www.hp.com/go/netservers).
Chapter 3 Procedure for Connecting and Routing Cables to the LH 3000r Mount Power Distribution Units Plan the location of the Power Distribution Unit or Units (PDU) by reference to amperage, power, and the number of receptacles. See Chapter 2, the section entitled "Wide Range PDU Configurations," particularly Table 2-4. Follow mounting instructions included with your power distribution units. Notice these cannot be installed behind some equipment. See Table 2-3.
