Data Express DE275 SAS/SATA Install Guide
Removable SAS/SATA Drive Enclosure
Frame Installation
For SATA operation connect a SATA data cable to the SATA/SAS
host 1 connector.
For SAS operation connect a SATA/SAS data cable to either
SATA/SAS Host 1 or SAS Host 2 connector.
For dual host capabilities connect SATA/SAS data cable to SATA/
SAS Host 1 and SAS Host 2.
Connect SATA power or ATX power to the power connectors on
the back of the DE275. The DE275 will support either ATX or
SATA power.
Slide the frame into an available drive bay and secure the frame.
Drive Installation
1. Carefully insert the drive into the carrier. Slide the drive
towards the Drive Carrier Board, so that the I/O connector on
the drive mates with the connector on the Drive Carrier Board.
Turn the drive/carrier assembly over.
2. Fasten the drive into place with the four provided #6-32 Phillips
Under Cut Flat Hd. Screws. Some drives may require minor
adjustment, to position the drive before securing into carrier
with screws.
3. Install the provided drive cover. Insert the front end of the cover
first and then slide the cover towards the rear of the carrier.
Secure drive cover with the two provided #4-40 Phillips Under
Cut Flat Hd. Screws.
The DE275 SAS/SATA enclosure is designed to incorporate the rug-
ged security of the DE200 with the low profile size of the DE75. The
DE275 includes two thumb screws for even greater stability. The 1”
low profile design of the DE275 minimizes the space required for
installation.
Note:
CRU recommends that the DE275 carrier not be used in
DE75 frames, nor should DE75 carriers be used in the DE275
frame. While the DE275 and the DE75 are physically the same
CRU does not intend for the product lines to be interchanged.
