SR Accessory Items 1-7
1.3. SR Accessory Items
The following items are not installed on the controller but come in the accessory box and
can be used with the SR controller.
1.3.1 Serial Cable
The IFT-9512 RS-232C serial cable allows the serial RS-232C serial communications
connector at the rear of the board (J2) to be connected to a PC hyper-terminal, which
enables a RAID array manager to easily manage and configure the storage array to which
the controller is connected.
1.3.2 Null Modem
The null model is a signal converter; please refer to Appendix D for more details.
1.3.3 Ethernet Cable
The receptacle side is shaped like a DB-9 connector and can be attached to the back panel
of the enclosure using the mounting positions of a serial port header to connect to the
outside of the enclosure.
1.3.4 Bezel Key
The IFT-9531 is used to remove the LCD front panel from the controller canister. The
only time the LCD front panel needs to be removed is when the controller board needs to
be accessed.
1.4. Separately Purchased Accessory Items
The following items are required to run the SR controller. You must purchase them
separately and install them yourself.
1.4.1 DIMM Modules
The SR controllers support PC-133 SDRAM DIMM modules with ECC support and
capacities between 128MB and 1GB. DIMM modules must be separately purchased and
installed by the end user. The SDRAM DIMM module socket is located on the controller
board and can only be accessed by removing the top cover of the controller enclosure.
NOTE:
Although the hardware is able to support a minimum SDRAM DIMM module size of
128MB, it is recommended that DIMM modules with a minimum capacity of 256MB
are used.
