2. Operating Your RAX
Connect the SFF-8088 data cable to the RAX and your host computer. Plug in the power cord.
With hard drives in the unit, turn on the power.
3. Dual Port Congurations
The RAX421D-XJ and RAX425D-XJ support two host machines connected
via two multi-lane SAS/SATA (SFF-8088) connections. Both hosts on a
dual port conguration cannot simultaneously write to the RAX unit. A
dual port conguration only ensures redundancy in case one host machine
is disabled or goes down.
Multi-lane SAS/SATA
4. Rack Mounting Warnings
