c. Hand tighten firmly against front rack post at the center of the rack ear flange.
d. Slide the ops panel cover over the left rack ear flange until flush with the rack post.
e. Repeat the process for the right rack ear flange and cover.

Populate the 2U enclosure

After successfully mounting the 2U chassis into the rack cabinet, populate the storage enclosure.
To populate the 2U enclosure:
1. Examine drive carriers for damage. If you installed a new drive in the carrier, verify drive connector pins are not bent.
2. Orient a drive in its carrier (DDIC) so the release latch is to the left for the 2U12 or to the top for the 2U24.
3. Insert it into the first available left-hand slot and press inward until fully seated against the midplane and the latch locks.
4. For the 2U12 storage enclosure, take the following actions until all slots hold either a DDIC or an optional blank carrier.
a. Insert the next DDIC and move across the row to the next slot in the sequence, repeating until the top row is full.
b. Repeat until the middle row is full.
c. Repeat until the bottom row is full.
5. For the 2U24 storage enclosure, insert the next DDIC and move across the row to the next slot in the sequence, repeating
until all slots hold either a DDIC or an optional blank carrier.
CAUTION If you partially populate the storage enclosure with drives in their carriers (DDICs), you must install a
minimum of one DDIC. For proper air flow, all drive slots must hold either a DDIC or an optional blank carrier. You may not
leave any empty slots.

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 2U enclosure power cords and data cables

When properly connected to autonomous power distribution units (PDUs), power cords provide uninterrupted power to the
storage enclosure and data 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 cooling modules (PCMs).
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.
