Major Subsystem Components
Figure 1-8: RAID Controller Faceplate
4G FC host ports:
Each controller module has four (4) FC ports with
the onboard hub functionality,
two (2) for each Fibre Channel. Each
host port comes with two (2) LEDs to indicate link and speed statuses.
Two (2) 4G FC host channels, CH0 and CH1, connect the subsystem to
the host computers equipped with 4G FC connectivity. The Fibre
Channel host ports receive 4.25/2.125GBd SFP, LC duplex type
transceivers and then connect to LC-type optical fiber cables.
SAS SFF-8470 Expansion Port:
This SAS expansion port allows you
to expand the raw capacity of your RAID subsystem with 3 (to dual-
controller RAID) add-on JBODs. For more information, please refer to
the documentation that came with the S16S-J1000 series expansion
enclosures or
Section 3.3
of this manual.
COM ports:
Each controller module comes with two (2) serial ports.
The
COM1
port is used for accessing the controller-embedded
configuration utility through a RS-232C serial connection and over a
VT-100 terminal emulation program running on a management
computer. A dual-audio-jacks-to-DB9 Y-cable for the RAID-R1430 is
included with the shipping package.
The second COM port, marked as
COM2,
is for connecting to an
uninterruptible power supply (UPS). An optional audio-jack-to-DB9
cable (PN: GAL-9270CUPSCab or GAL-9270CUPSYCab) is available
for purchase.
Ethernet port:
All controller modules on the RAID come with a
10/100BaseT Ethernet port that can be used for local/remote
management. When operated in the dual-active mode, system
configuration is handled through one of the controllers. In the event
when one controller fails, the Ethernet port on the surviving controller
inherits the configured IP and continues the monitoring or
configuration session. Shielded cables are recommended to protect
against emissions. Connect the other end of the Ethernet cable to a
LAN port of your local network.
