1: Detailed Chassis Description

Hard Drive Bay

10
The chassis contains one hard drive bay. The hard drive bay accommodates up to five
3.5-inch by 1.0-inch hot-swap Ultra 160 SCSI SCA hard drives
You can access the hard drives by opening the front bezel door. As part of the hot-swap
implementation, each hard drive requires a hard drive carrier. When you remove a hard
drive from the system, you remove both the carrier and the hard drive. The drive is
attached to the carrier by four screws. The carrier locks into the hard drive bay by a
locking handle. Figure 1-5 shows the orientation of the drive in the carrier. The carrier is
upside down in this figure.

Each hard drive is connected to an Ultra 160 SCSI hot-swap backplane. The backplane
provides industry-standard 80-pin SCA-2 connectors for each hard drive and accepts
10,000 RPM or slower drives that consume up to 23 watts of power. If another type or
slower Ultra 160 SCSI SCA drive is installed, make sure that the drive meets these
backplane and carrier requirements.
