September 2005 2-19
2.7.2 Module Installation
Installation Procedure (Refer to Figure 2-8):
1. Refer to user documentation for the EAM MODULRAC slot number.
2. Remove the EAM from its static shielding bag and ensure that the module is keyed. Also, check the
MODULRAC slot to be sure it is keyed. Refer to section 2.7.1 to install keying.
3. Insert the module in the assigned MODULRAC slot. Firmly seat the module in the backplane and
termination board connectors. A properly seated module will have the rear of its bezel flush against
the MODULRAC’s front rails. A keyed module that is not matched to a slot will not engage the
backplane or termination board connectors or seat flush against the MODULRAC’s rails.
4. Pull open the bezel’s pivoting top and bottom handles to expose the slotted captive mounting screws
and secure the module to the top and bottom rails. Close the bezel’s handles when finished.
IMPORTANT
Do not use the captive mounting screws to seat the module. Damage to
the bezel can result.
2.8 Electrical Installation
The following sections describe I/O cable connections to an EAM Termination Strip or EAM Marshalled
Termination Assembly. It is assumed that tagged I/O cables have been pulled into the cabinet and are
ready for preparation and connection.
