Installing Modules; Removing A Module - Symmetricom TSG-3800 Series User Manual

Installing Modules

The installation procedure is common for all modules. Some modules require the
operator to set or verify jumper positions. Refer to
Chapter 6, CPU, Frame Generator, and Clock
Modules for any other precautionary or special instructions for the modules you are
installing.
Note: Modules can be installed and removed while system power is
applied unless otherwise indicated.
To install a module:
1. Align the module card edges with the plastic card guides of the selected slot.
2. Slide the module evenly into the TSG-3800 Main shelf until it seats fully into the
connector on the Interconnect Board.
3. Tighten the retaining screws located at the top and bottom of the module's front
panel.
Caution: To avoid damage to the modules, be sure to completely
insert the module into the Interconnect Board and securely tighten the
retaining screws. A partially inserted module can easily become
damaged.

Removing a Module

The removal procedure is common to all modules. Always use proper handling
techniques when removing the modules. Refer to
Chapter 6, CPU, Frame Generator, and Clock
Modules for any other precautionary or special instructions for the modules you are
removing.
To remove a module from the shelf:
1. Loosen the retaining screws located at the top and bottom of the module. Ensure
that these screws are completely disengaged from the shelf.
2. If the removal tool (item number 00478507-000-1) is available, insert it onto the
shafts of the retaining screws and pull firmly and evenly to remove the module.
If the removal tool is not available, grasp the retaining screws and pull firmly and
evenly at the top and bottom of the module until it is completely out of the unit.
3. Replace an open slot with another module or with a blank filler slot (item number
