SAS Host Ports:
Each RAID controller features three (3)
SAS ports labeled
CH0
,
CH1
, and
SAS Exp
. The 4x multi-
lane SAS port complies with the SFF-8088 specification, and
is capable of 24Gb/s wide link bandwidth at full-duplex
operations.
The expansion port from each RAID controller connects an
independent SAS domain. Path redundancy is achieved by
connecting different SAS domains between RAID and
JBODs; i.e., RAID controller A Exp. to JBOD controller A and
RAID controller B Exp. to JBOD controller B.
Two (2) plastic caps cover the SAS ports to prevent
connector contacts from pollutions. Removing the plastic
caps before connection is not recommended. Keep the
plastic caps for future use.
Status LEDs:
Refer to Chapter 4 for the definitions of
controller LEDs.
Serial Ports and Ethernet Ports:
These are the
management interfaces providing access to firmware
embedded utility or a Java-based software console.
Restore Default
(non-latch button & LED):
Restore Default Button/LED:
Pressing and holding the
button down while powering on the subsystem will restore
firmware default settings.
CAUTION!
The Restore NVRAM Default push button is a function that carries
some risks. Firmware restoration will not destroy the existing logical
drive configurations; however, if the existing logical drives cannot
be adequately associated with host ID/LUNs after firmware default
restoration, data loss or inconsistencies may occur.
