Returning Equipment
To install the new module:
1. Verify that you are properly grounded with an anti-static wrist strap or heel strap
connected to the grounded ESD jack.
2. Hold the replacement PSM-DC upright with the faceplate toward you.
3. Insert the PSM into the appropriate slot.
4. Gently apply pressure to the faceplate while you push the module into the slot.
5. Push on the faceplate to fully seat the module. The module is completely inserted
when its faceplate is flush with the faceplates of the adjacent modules and the shelf
panels.
6. After you have completely inserted the PSM, hand-tighten the thumb screws to
prevent inadvertent dislodging.
7. Use a Torx T10 screwdriver to gently tighten the retaining screw as needed. Do not
overtighten.
8. The Mod LED of the PSM-DC should turn green to indicate that the units are
functioning properly.
9. Reinstall the front cover as described in Removing and Installing Front Covers.
If the Mod LED of the PSM-DC is off, no power is being supplied to the
unit. In case of an error, the power LED turns red. For troubleshooting
information, see Troubleshooting with Component LEDs or contact
ADVA Optical Networking for technical assistance.
