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.

Frame Data Connectivity – 

For SATA operation the SATA data 

cable must be connected to the SAS/SATA Host 1 Connector. 
SATA hard drives do not support the SAS Host 2 Connector. SAS 
hard drives can use either SAS Host 1 Connector or SAS Host 2 
Connector. The DE275 supports the SAS dual host feature for fail 
over protection.
