Figure 323: ETERNUS CS800 S6 Entry SAS cabling with up to three JX40 S2 enclosures
The SAS IN port of JX40-1 has to be connected to the upper port of the SAS RAID
controller in PCI slot 7 of the server. The SAS OUT port of JX40-1 has to be connected to
the SAS IN port of JX40-2 and so on.
5. If the disks are not already inserted to the ETERNUS JX40 S2: Replace the blank inserts
one after the other by 3.5” 4TB Nearline SAS 7,200 rpm hard disks. The slots you have
to fill up with disks are shown by figure "Disk bays in JX40 used for storage expansion
from 24TB to up to 120TB”.
CAUTION!
l
To avoid temperature rise, replacing a hard disk should be finished within 5
minutes if the ETERNUS JX40 S2 is operating.
l
Because of cooling, adherence to EMC (electromagnetic compatibility)
requirements and fire protection all unused bays must be filled up with blank
inserts.
6. Connect a power cord to each power supply of the storage modules.
It is recommended to connect each power cord (two per module) to a separate
AC circuit in order to ensure system availability in case of a power failure.
