Switch S2 is used for diagnostic purposes. It provides no user
options and must be set as follows:
Dipswitches S3 and S4
When used at the local end, dipswitches S3 and S4 disconnect
the Expander Bus signals that go to the driver section. Position
4 of S3 must be set to match the cable type in your system. The
choices are either electrical (standard INFI 90 cable) or fiber
optic cable. The switches are set as follows:
PHYSICAL INSTALLATION
After setting the switches, the RIO is ready to be placed in the
MMU. The MMU provides slots for up to twelve modules. The
RIO occupies one slot in the Module Mounting Unit. The mod-
ule front plate has two captive screws that secure the module
to the MMU. The RIO may be mounted in any slot provided
connection to the Expander Bus. Twelve position dipshunts
insert in the 24 pin sockets at the interior bottom of the MMU
backplane between adjacent modules. This provides Expander
Bus communication between Master Modules and their slaves.
