8–6 Model 2100 and 2200 Ultra SCSI Controller Enclosures User Guide
I/O Module
Each I/O module functions independently of the others, but all I/O modules within the
enclosure must be the identical model. Figure 8–4 correlates each I/O module bay to a
specific SCSI bus number.
Figure 8–4. I/O module bay to SCSI bus number correlation
NOTE:
Model 2100 enclosures support only two I/O modules—SCSI bus 1
1
and SCSI
bus 2
2
; whereas Model 2200 enclosures support all six I/O modules. For Model 2100
enclosures, a blank panel covers the four vacant I/O module bays.
The I/O module is pluggable. See Figure 8–5 as needed during the removal and
installation. Complete the procedure in Table 8–4 to remove an I/O module. Complete the
procedure in Table 8–5 to install an I/O module.
