• When connecting two or more Drive Boxes, both ENC1 and ENC2 should be
connected with the SAS cables for the Drive Boxes.
• When bending the SAS cable/NVMe cable to connect it, give it a bend with a
long radius (not less than 40 mm) so as not to apply the cable and the connector
excessive stresses. Wind the cables to be φ 200 mm or more as a guide.
• If you insert it incorrectly, remove the SAS cable/NVMe cable while pulling the tab
of the cable.
• Before wiring SAS cables/NVMe cable, unwind, stretch and untwist them.
If they twist while wiring, untwist and wire them.
• When inserting the connector into the socket, do not rotate the connector 90 degrees
or more.
When rotating 90 degrees or more, rotate the connector and the cable together,
match the insertion direction of the connector and connect it. Before wiring SAS
cables/NVMe cable, unwind, stretch and untwist them.
