INSTALLATION
INSTALLING THE INTERFACE MODULES
I-E96-607A
3 - 25
To install the INIIT03 and INNIS01 modules:
1. There must be 3 empty slots (side by side, see Figure
available in 1 MMU card cage to install 1 interface (6 slots for a
redundant interface).
2. Verify that there are 24-pin dipshunts installed in the I/O
expander bus sockets between the MMU slots to be used by
both NIS modules and the slot to be used by the INIIT03 mod-
ule. When installing a redundant interface, the modules that
make up the primary IIL interface must be on a separate I/O
expander bus from the modules that make up the secondary
IIL interface.
3. Mount each module in its assigned MMU slot one at a time.
4. Guide the top and bottom edges of the circuit card along
the top and bottom rails of its assigned MMU card cage slot.
5. Slide the module into the slot; push the module until the
front panel is flush with the top and bottom of the MMU frame
and seated within the cable connector at the rear of the MMU
card cage.
6. Turn the 2 captive latches ½-turn to lock the module in
place.
The modules can be installed under power. Install the INIIT03
module last, otherwise the status LED turns red. When install-
ing a module under power, the status LED will turn red
momentarily and then turn green. If it does not, refer to
.
