Ce Compliant Replacement Procedure - Honeywell HPM Service

CE Compliant replacement procedure

Use the procedure in the following table to replace the Fiber Optic Coupler module when the coupler is
installed in a CE Compliant card file.
Step
1
Grasp the upper and lower extractors on the I/O Link Extender card and pull them
outward in unison. Move the card toward you until the card is disengaged from the card
file backpanel connector. It is not necessary to remove the card from the card file.
2
Disconnect the fiber optic cables from the Fiber Optic Coupler module. Be sure the
cables are properly labeled.
3
Using a screwdriver with a small blade, loosen the two screws that secure the fiber
optic coupler to the backpanel connector. Grasp the module firmly in your hand and pull
it towards you.
The adapter connector that is between the Fiber Optic Coupler module and the
backpanel connector may remain in place in the backpanel connector or disengage
with the module. See Figure 207 for an illustration of the Fiber Optic Coupler module
components.
Remove the adapter connector from the module and place the module on an antistatic
surface or in an antistatic container.
4
Replace the defective module by reversing step 3.
5
Reconnect the fiber optic cables to the module.
6
Reinstall the I/O Link Extender card by reversing step 1.
7
When you replace a Standard I/O Link Extender Fiber Optic Coupler module, you must
initialize both ends of the link(s) by manually resetting the I/O Link Extender cards
using the upper card extractor on the card.
When a Long Distance I/O Link Extender Fiber Optic Coupler module is replaced,
reinstalling either I/O Link Extender card produces initialization at both ends of the link.
