SFP transceivers: If the FC cables that were previously purchased do not come
with pre-installed SFP transceivers, SFP transceivers with LC-type, multi-mode
cables must be separately purchased. (See Section 4.2.3)
(2). One (1) audio-jack-to-DB9 cable is provided to facilitate the connection of the
COM1 port for local terminal emulation access to the array.
(3). Two (2) power cords are provided for the power connections to the power
sources.
(4). The RJ-45 Ethernet cable for network management connection is a user-supplied
item.
5. Memory modules: If you wish to change the pre-installed memory modules, the
separately purchased modules must be installed. Please contact your vendor for a
different memory module or consult the list of compatible modules.
6. BBU module: If you wish to use a BBU module, the module can be purchased
separately.
7. Rack installation: The enclosure chassis can be installed into a rack cabinet using

2.3 Safety Precautions
2.3.1 Precautions and Instructions
1. Be sure the correct power range (100~120 or 220~240VAC) is supplied by your
rack cabinet, UPS device, or power outlet.
2. Thermal notice: All drive trays (even if they do not contain a hard drive) must be
installed into the enclosure. Leaving a drive bay or module slot open will greatly
affect the efficiency of airflow within the enclosure, and will consequently lead to
system overheating. Keep a faulty module in place until you have a replacement unit
and you are ready to replace it.
3. An enclosure without disk drives can weigh up to 24 kilograms. Two (2) people will
be required to install or relocate the subsystem. Drives should be removed from the
enclosure before moving the subsystem.
4. Airflow considerations: The subsystem requires an airflow clearance especially on
the front and on the rear. A minimum of 2.5cm is required between the front of the
