1-2 SAS Expander
The SSG-937R-E2CJB includes two AOM-SAS3-937EL-JB expanders mounted in
hot-swappable trays. The AOM-SAS3-937EL-JB utilizes the LSISAS3x40, which is
a 40-port, 12 Gb/s SAS expander.
Cascading
Each AOM-SAS3-937EL-JB has two SAS-IN and two SAS-OUT ports, which are
located at the rear of the chassis. The IN ports are used to connect to a SAS con-
troller while the OUT ports are used to cascade to other JBODs.
IPMI
Each AOM-SAS3-937EL-JB comes with an onboard Aspeed2400 controller, which
provides system management. The IPMI interface is accessible through an RJ45
port at the rear of each node. This dedicated IPMI RJ45 port is set to DHCP by
default. Depressing the reset button for 6 seconds will change it to a static IP
address of 192.168.1.99. Depressing the reset button again and holding it for 12
seconds will set it (along with any other BMC settings) back to the factory default.
1-3 Server Chassis Features
System Power
The system features a redundant Titanium Level 1200W power supply composed of
two separate power modules. This power redundancy feature allows you to replace
a failed power module without shutting down the system.
SAS Subsystem
The SSG-937R-E2CJB supports up to 16 3.5" SAS drives. These drives are
hot-swappable and are connected to a midplane that provides power and control.
Front Control Panel
Two control panels are included on each end of the SSG-937R-E2CJB to provide
you with system monitoring and control. LEDs indicate system power, cascade
status, system overheat and power supply failure. Each set of LEDs are associ-
ated with the node/serverboard on the same side of the chassis. A single power
button is located on the right side control panel. When pressed, both nodes will
power on or off.
