After you install the hard disk drives and power supplies, follow the instructions in this section to complete the installation. Instructions for installing the identification labels and cabling the storage unit are included.
Your storage unit comes with one sheet of 10 labels (0-9) and one sheet of 4 labels (SCSI ID) labels.

This section provides the SCSI and power cabling information. After you attach your SCSI and power cables, use the instructions provided in "Switching the storage unit on and off", for the initial startup of the storage unit.
The storage unit comes with two ESM boards. There are two 68-pin SCSI Very High Density Connector Interface (VHDCI) connectors. From left to right as seen from the back, these connectors are for SCSI bus 2 and SCSI bus 1. See "Rear controls, indicators, and connectors", for the location of these connectors.
The SCSI controller inside your server must have a dedicated SCSI channel for the storage unit. If an external channel is being used for the storage unit, its corresponding internal channel must not be used for other devices.
The storage unit uses two or four power cords, depending on your country. You can connect the power cords to a primary power unit inside the rack, such as a properly grounded ac distribution unit or uninterruptible power supply (UPS), or to an external source, such as a properly grounded electrical outlet.
Attach the power supply power cords as follows:
