2. Close the cover-release latch.To install the bezel:1. Align the trim bezel with the front of the server.2. Press inward on the top sides of the bezel and press the bezel toward theserver until it clicks into place.To complete the installation:If you disconnected any cables from the back of the server, reconnect the cables;then, plug the power cords into properly grounded electrical outlets.Connecting external optionsIf you install a SCSI adapter, you can attach a SCSI storage expansion enclosure toyour server.Cabling requirementsTo select and order the correct cables for use with external devices, contact yourIBM reseller or IBM marketing representative.For information about the maximum length of SCSI cable between the terminatedends of the cable, see ANSI SCSI Standards:v X3.131-1986 (SCSI)v X3.131-1994 (SCSI-2)v X3T10/1071DAdhering to these standards ensures that your server operates properly.Setting SCSI IDs for external devicesEach SCSI device that is connected to a SCSI controller must have a unique SCSIID, so that the SCSI controller can identify the devices and ensure that differentdevices do not attempt to transfer data at the same time. SCSI devices that areconnected to different SCSI controllers can have duplicate SCSI IDs. The SCSIcontroller uses one of the SCSI IDs; the default SCSI ID for the SCSI controller is 7.Refer to the instructions that come with the SCSI devices for more informationabout setting a SCSI ID.Installation procedureTo attach an external device:1. Turn off the server and all attached devices.2. Follow the instructions that come with the option to prepare it for installationand to connect it to the server.Input/Output portsThis section provides information about the input/output (I/O) ports on the rearof your server. These ports include the following:v One Video portv One Keyboard portv One Auxiliary-device (pointing device) portv Two Serial portsv One RS-485 port with two RS-485 interface connectors (ISM-A and ISM-B)v Two Universal Serial Bus portsInstalling options 63
