5. Following the same drawer closure process, completely close the drawer until it fully latches.

Test enclosure connections

After completion of all installation procedures, the storage enclosure is ready for connection to power. You can only connect
the storage enclosure to a power source that has a safety electrical earth connection. Have a qualified electrical engineer
confirm the earth connection meets the product specifications.
CAUTION If you install multiple storage enclosures in a rack cabinet, the importance of the earth connection increases,
since each storage enclosure increases earth leakage current.
IMPORTANT Only a qualified electrical engineer who meets local and national standards should perform the inspection.

Route 5U enclosure power cords and data cables

When properly connected to autonomous power distribution units (PDUs), power cords provide uninterrupted power to the
storage enclosure. Data cables, such as fibre channel (FC), SAS, or 10GBase-T cables, provide an efficient highway for data
exchanges to and from the storage enclosure. You must properly route both while adhering to all grounding requirements and
electrical safety precautions.
To adhere to electrical safety precautions:
1. Observe the caution labels affixed to the power supply units (PSUs).
2. Confirm PCM input voltage range is 100-240VAC at 50 to 60Hz, then only operate the storage enclosure in that range.
3. You must provide a suitable power source with electrical overload protection to meet technical specification requirements.
4. You must use a provided power cord that has a tested, safe electrical earth connection for storage enclosure power supply.
5. Confirm the storage enclosure connection to earth before applying power to it.
6. Do not operate a storage enclosure with less than the provided 2 PSUs and 5 fan control modules (FCMs, other than to
provide in-service maintenance within the required time allotment.
IMPORTANT Use only Cat-6 or above cables with RJ-45 connectors for Base-T connections.
IMPORTANT Use only Seagate approved HD mini-SAS (SFF-8644) x4 data cables that are at least .5m (1.64 ft) in length
and do not exceed 3m (9.84 ft) in length to connect to the SAS ports on each controller module.

Route 5U enclosure and expansion data cables

The 5U storage enclosure supports SAS cabling for up to 9 expansion enclosures and several methods for connectivity to a
switch or the host system. Select data cables that best align with available controller module ports and your host environment.
Fault tolerance and performance are key factors in determining how to best optimize your system and cabling configuration.
This topic assumes a fault-tolerant reverse cabling method, since it provides a method of maintaining access to all enclosures
in the chain, even if one of the enclosures fails or requires removal. If you use a straight-through cabling method, optimized for
high performance, it is less fault tolerant. When using straight-through cabling, a failed enclosure in the chain prevents access
to enclosures further down the chain until you address the fault.
You must comply with all SAS cabling requirements and confirm that they meet all related standards.
