SR1202 RAID Controller Module
One or two SR1202 RAID Controller Modules (according to customer configuration) are supplied
mounted in the rear of the enclosure as part of the SR1202 enclosure core product.
The plug-in SR1202 RAID Controller Modules have been designed for integration into a SR1202
enclosure, providing external FC cable interfacing with the host computer system.
The Backplane incorporates connection to each of the SAS ports within the SR1202 RAID Controller
Modules.
The SR1202 RAID Controller Module internal processor monitors error conditions on each disk drive
port.
Processors housed on the SR1202 RAID Controller Modules provide enclosure management interfacing
to devices on the Backplane, PSU, SR1202 RAID Controller Module and Ops Panel, to monitor internal
functions.These processors operate in a dual active configuration to allow failover.
The module incorporates LED indicators, shown in Figure 18. Please refer to Table 10, ”SR1202 RAID
Controller Module LEDs”, on page 42 for details of the LED status conditions.
The SR1202 RAID Controller Module operates at 4 Gb/s and has the following external ports:
• Two external ports that allow for fitting of Small Form Factor Pluggable (SFP) modules, with
autobypass at the output ports. Either of these SFP ports can be used to provide connection to
the Host controllers.
• An SFF Expansion port provides SAS expansion connections, up to a maximum of 4 additional
enclosures.
• An RJ45 10/100/BaseT Ethernet port provides networking connection.
• There is also an RS232 socket which is for service personnel or end-user use only.
