1.2.3SCM Input/Output Module

The DCS9550 1S1 Storage Expansion Unit includes an enclosure with rear facing bays which houses one or two SATA Control Interface Adaptor (SCM I/O) modules (see Figure 1–3), dependent on configuration required.

The plug-in SCM I/O modules have been designed for integration into a DCS9550 1S1 Storage Expansion Unit, providing external FCAL cable interfacing with up to 16 SATA disk drives.

Processors housed on the SCM I/O modules provide enclosure management and interface to devices on the Backplane, PSU, SCM and Ops Panel, to monitor internal functions.

The module incorporates the following LED indicators:

Host

Important If only one SCM module is fitted, the SCM module must be installed in Rear Bay 4 location [see Figure 1–3, ”Enclosure Chassis (Rear)”, on page 2] and a Blank I/O module fitted in the unused

bay.
