Replacing an Encryption Module
Step 2 Follow ESD safety guidelines. Attach the grounding wire to the ESD jack on
the shelf, and then secure the grounding wire to your wrist.
Step 3 Locate the shelf within the NE where the module should be inserted.
Step 4 If the front cover is mounted, remove the front cover, as described in
“Removing an SH7HU, SH9HU, or SHX9HU Front Cover” on p.768.
Step 5 Locate the slot where the encryption module is to be installed.
Step 6 Check the operating status of the equipment and the current hazard level. If
any module in the system is operating in “Forced On” mode, this may raise the
hazard level of the NE. Do not proceed unless you are trained in laser safety.
Step 7 Remove the corresponding dummy module from the slot, as described in
“Removing a Dummy Module” on p.775.
Never reach into a vacant shelf slot. Contact with the adjacent optical modules or
backplane connectors can damage the equipment.
Step 8 Remove the encryption module from the shipping box. Remove the static-
protective package, and then immediately place the module on a grounded
surface or an antistatic mat, to avoid ESD damage.
Step 9 Check the module as follows:
a) The module is protected with seals and rivets. Ensure that nothing has
been damaged and that the module was not opened and/or modified.
b) Ensure that the module is the correct one you want to install (type,
specifications). Refer to the faceplate markings and the labels on the
board cover.
c) Inspect the module for any damage and impurities. If necessary, use
canned, dry, oil-free compressed air to blow off any dust particles.
• Carefully check the plug-in board connector of the optical module for dirt,
any deformation in the shape of the pin holes, or external damage.
• Check the contact strip or EMI shielding gasket on the faceplate edges of
the module for damage.
Do NOT install modules:
• That have broken seals or rivets. This could be a sign of tampering or
damage.
• That have been dropped on a hard surface.
• That have loose or torn contact strips or EMI shielding
Return these modules to ADVA Optical Networking for examination and repair.
Step 10 Check inside the shelf to ensure:
• no foreign conductive bodies are present between pins on the backplane
connectors
• no pins on the backplane connectors are bent or broken.
Do NOTinstall the module if a backplane connector of the shelf is damaged.
