Installing VXI
Modules
Install C-size VXI modules directly into the C-size slots (6) of the
mainframe by first placing the module’s card edges into the front
module guides (top then bottom). Slide the module to the rear of
the mainframe until the module connectors mate solidly with the
backplane connectors. Secure the module’s front panel to the
mainframe using the module’s front panel mounting screws.
CAUTION
To avoid possible damages do NOT hot-plug install
VXI modules (i.e., install with power on).
Installation and
Removal of
Card Guide
Covers
In order to improve cooling of used slots in the VXI mainframe, a
limited number of the optional card guide covers, P/N 456271, may
be installed at empty C-size slot locations to redirect otherwise
wasted airflow.
CAUTION
To maintain a balanced airflow throughout the
system when using card guide covers, do not cover
more than three empty slots at any time. If module
density is low, space airflow covers evenly across the
mainframe.
Figure 2-1, AirFlow Directors (Card Guide Covers)
1. Facing the front of the VXI mainframe, with one hand hold the
cover by the front end where the “Racal” logo appears.
2. Select the slot to be covered by the cover. Insert the hook at
the rear of the cover into the rectangular slot at the back of
the cardguide (1). Apply a slight downward pressure on top of
the cover (with the other hand) at the rear to engage the hook
into the cardguide.
