NOTE! The term hot pluggable refers to modules that can be replaced while the host and
storage system are operating, without disrupting their operation. Not all modules are hot
pluggable, and some modules require the use of command line utilities before the module is
removed, and after the module is replaced. The storage systems do not support installation of
additional disk modules or DDS tape modules while the host and storage system are operating.

Fan Modules
The storage system is shipped with two fan modules, which provide redundant cooling. If one fan fails,
the remaining fan will provide enough cooling capacity for the storage system. Fan modules are hot
pluggable. Failed fan modules should be replaced as soon as possible.

Power Modules
The storage system is shipped with one power module. Two power modules provide redundant power for
the storage system. If one power module fails, the storage system continues operating on one power
module. If two power modules are used, both share the load. Power modules are hot pluggable.

Disk Modules
The storage system can contain any combination of 1-inch-high and 1.6-inch-high disk modules. A 1-inch
disk module occupies one slot in the storage system, and a 1.6-inch disk module occupies two slots. The
disk modules are available with either a single-ended (SE) or fast/wide differential (DF) SCSI interface.
The disk module is enclosed in a plastic module, so SCSI address (ID) jumpers are not accessible. SCSI
ID switches on the rear of the storage system are used to set the disk module SCSI ID.

DDS Tape Module
A 1.6-inch-high, single-ended DDS tape module can also be installed into the storage system. The DDS
tape module occupies two slots. The DDS tape module is enclosed in a plastic module, so tape module
jumpers and SCSI address (ID) jumpers are not accessible. SCSI ID switches on the rear of the storage
system are used to set the DDS tape module SCSI ID.
A 1.6-inch-high, single-ended DDS tape module can also be installed into the storage system. The DDS
tape module occupies two slots. The DDS tape module is enclosed in a plastic module, so tape module
jumpers and SCSI address (ID) jumpers are not accessible. SCSI ID switches on the rear of the storage
system are used to set the DDS tape module SCSI ID.
