1. Remove and retain the thumb nuts from the studs. 2. Install the line cord anchor over the studs. Refer to Figure 2-27: "Two Cell Line Cord Anchor (rp7410, rp7420, rp7440, rx7620, rx7640)", 3. Tighten the thumb nuts onto the studs. 4. Weave the power cables through the line cord anchor. Leave enough slack to allow the plugs to be disconnected from the receptacles without removing the cords from the line cord anchor. 5. Use the supplied straps to attach the cords to the anchor. Refer to Figure 2-28: "Line Cord Anchor Attach Straps", Figure 2-27 Two Cell Line Cord Anchor (rp7410, rp7420, rp7440, rx7620, rx7640) Figure 2-28 Line Cord Anchor Attach Straps Core I/O Connections Each server can have up to two core I/O board sets installed which allows for two partitions to operate, or MP core I/O redundancy in a single or dual partition configuration. Each core I/O board set consists of two boards: the MP/SCSI board and the LAN/SCSI board. The MP/SCSI board is oriented vertically and accessed from the back of the server. The LAN/SCSI is accessed from the PCI expansion card bay. Only the primary core I/O board set (MP/SCSI slot 1 and LAN/SCSI slot 8, chassis 1) is required for a single partition implementation. The secondary MP/SCSI board is not necessary for full operation; however, without the secondary MP/SCSI and LAN/SCSI boards, only the top two internal disks can be accessed. MP/SCSI I/O Connections The MP/SCSI board is required to update firmware, access the console, turn partition power on or off, access one of the HDDs and one of the removable media devices, and utilize other features of the system. For systems running a single partition, one MP/SCSI board is required. A second 60 Installing the Server

Core I/O Connections
Each server can have up to two core I/O board sets installed which allows for two partitions to
operate, or MP core I/O redundancy in a single or dual partition configuration. Each core I/O
board set consists of two boards: the MP/SCSI board and the LAN/SCSI board. The MP/SCSI
board is oriented vertically and accessed from the back of the server. The LAN/SCSI is accessed
from the PCI expansion card bay. Only the primary core I/O board set (MP/SCSI slot 1 and
LAN/SCSI slot 8, chassis 1) is required for a single partition implementation. The secondary
MP/SCSI board is not necessary for full operation; however, without the secondary MP/SCSI
and LAN/SCSI boards, only the top two internal disks can be accessed.
MP/SCSI I/O Connections
The MP/SCSI board is required to update firmware, access the console, turn partition power on
or off, access one of the HDDs and one of the removable media devices, and utilize other features
