Wrap plugs areshipped automatically when a Fibre Channel featurecode is ordered.B1A38B24 Network configuration Ensure that you have entered the correct IP address.Best practices for integrating cable and system placementThese guidelines ensure that your system and its cables have optimal clearance for maintenance andother operations. The guidelines also provide guidance in correctly cabling your system and using theappropriate cables.The following guidelines provide cabling information for installing, migrating, relocating, or upgradingyour system:v Position drawers in racks to allow enough space, where possible, for routing cableson the bottom andtop of the rack, and between drawers.v Shorter drawers are not placed between longer drawers in the rack (for example, do not place a 19-inchdrawer between two 24-inch drawers).v When a specific cable plugging sequence is required, for example, for concurrent maintenance(symmetric multiprocessing cables), label the cables appropriately and note the sequence order.v To facilitate cable routing, install cables in the following order:1. System power control network (SPCN) cables2. Power cables3. Communications (serial-attached SCSI, InfiniBand, remote input/output, and peripheral componentinterconnect express) cablesNote: Install and route the communications cables, starting with the smallest diameter first andthen progressing to the largest diameter. This applies to installing them into the cable managementarm and retaining them to the rack, brackets, and other features that may be provided for cablemanagement.34 Power Systems: Installing the IBM Power System S822 (8284-22A)
