Appendix A Replacing and Upgrading FRUs
A.1 Installing or Replacing Drives
Before you install or replace drives, plan where you will be placing the disk drives. If an
array will not be fully populated with drives, be sure the drive slots contain drive trays
and/or blank filler panels. For more information, see Figure 2-3 and Section 2.1.
High Availability (HA) Note: A system using a single controller (DSN-5210 or
DSN-5410) and its expansion array(s) may use SAS or SATA drives. A system
using dual controllers for High Availability operation (DSN-520 for the 5210
or DSN-540 for the 5410) requires SAS drives be used in both the primary
array and any expansion array(s).
If you anticipate upgrading to HA with the addition of a second controller,
then it is recommended you install SAS drives.
Also, do not mix SAS and SATA drives in the same storage system.
To install a drive, use the following procedure.
1.
On the front of the enclosure, select an open drive slot.
2.
Select the right type of drive for this drive slot (see the figures above).
3.
Hold the drive so the LEDs are on the left and the lever is fully open. Then slide the
drive into the drive slot until the lever starts to close.
Figure A-1. Installing a Drive
4.
Gently push the lever until it meets the latch on the left side of the drive slot and clicks
into place.

5.
To install additional drives, repeat this procedure.
