Chapter 3 Procedure for Connecting and Routing Cables to the LH 3000r and monitor for more than one server, attach the cables for the HP Console Switch to the server ports for video, mouse, and keyboard ports. Check Whether Cable Lengths Limit Distances between the Server and Storage Sometimes data cable length or availability limits the distance between a peripheral component (such as the UPS or video monitor) and its associated server. Guidelines used by rack configuration tools in generating rack layouts take possible distance limitations into account. Check power and data cords supplied with peripherals to ensure you have cables that are long enough to attach each device. NOTE Be sure to leave sufficient data cable length to allow for cable management. See the section of this chapter "Managing and Routing Cables" and refer to Figure 3-10. Attach Data Cables to Other Components 1. Using the colored cable ties and labels attached to each data cable previously, connect each cable to its component. 2. Fasten cable connectors to each component using captive screws. Step 3: Cable the LH 3000r for Power When all components have been mounted in the rack and their data cables connected, then the power cables can be attached. Attaching Server and Component Power Cables 1. Make sure any manually switchable device power switches are off. 2. Attach the power cords for each device. ◊ Plug power cords into the receptacle in the server. ◊ Ensure sufficient cable to fully extend the server and route cables through the Cable Management Arm. ◊ Route the cables through the Cable Guide. ◊ Tie bundles of cables using hook-and-loop cable straps. 3. Plug components into the PDU beginning with the components which are lowest in the rack. If you are using more than one PDU or have a heavily loaded rack, see the section of this chapter entitled "Determining and Balancing Current Draw on Two Circuits in One Rack." 37
