1. Follow the instructions in your expansion unit installation manual to set up and
mount the new expansion unit.
2. Use the following procedure and illustration to connect a single expansion unit
to the storage server:
a. Use a fiber-optic cable to connect to the FC-Expansion Units port on the left
RAID controller in the storage server to the In port on the left ESM board of
the expansion unit.
b. Use a second fiber-optic cable to connect the FC-Expansion Units port on
the right RAID controller in the storage server to the Out port on the right
ESM board of the expansion unit.
c. Ensure that the enclosure ID switch is set to a value different from one set
for the FAStT600 server and other drive expansion enclosures in the loop.
Also, ensure that the link speeds of the expansion units are set to 2 Gb.

3. Remove the blank filler trays and insert drive trays. Connect power to the
storage server, and then connect power to the drive expansion enclosures. After
the enclosures are powered-on, the storage server locates the new drives.
4. Use the storage-management software to check the status of the new drives,
correct any errors found, and configure the new drives.
Use the following procedure and illustration to connect a second expansion unit to
the storage server after previously adding the first expansion unit:
1. Ensure that the enclosure ID switch is set to a value different from one set for
the FAStT600 server and other drive expansion enclosures in the loop. Also,
ensure that the link speeds of the expansion units are set to 2 Gb.
2. Disconnect cable ▌1▐ from its current connection and connect it to the In port on
the left ESM board on the new expansion unit.
3. Connect cable ▌2▐to the In port you disconnected in step 1 and the Out port on
the left ESM board on the new expansion unit.
4. Connect a third cable ▌3▐ to the In port on the right ESM board on the first
expansion unit and the Out port on the right ESM board on the new expansion
unit.
