3.6 Mounting Option Boards
If installing option boards into a CAB-4 Series backbox, mount and connect those boards at this
time. General instructions follow; the sections about individual option boards contain any module-
specific instructions such as mounting LEM-320’s stacker-connector.
3.6.1 Option Boards in the IQ-636X-2/E Chassis
Mount option boards in slots 3 and 4 of the IQ-636X-2/E chassis. (See Figure 3.2, Figure 3.6, and
Figure 3.7.) For standoff lengths, see Table 3.2.
NOTE:
Another option board can be mounted above a Loop Expander Module; for ease of
access, be sure to complete installation of those devices before mounting a second layer.
NOTE:
If using the fourth (right-side) position of the IQ-636X-2/E chassis, the chassis needs to
be installed on the backbox before option boards or modules are installed in that position. These
modules will block access to the keyhole opening.
