SAM Replacement
SAM Replacement
There are no field repairable items on a SAM. All user equipment connected to the
defective SAM will lose ATM connectivity during replacement. Equipment connected
via other SAM(s) will not have an ATM service disruption. Follow the steps below to
replace a SAM:
1. Ensure that you have a replacement module.
2. Remove the chassis front cover. The Broadmore 1750 retains power;
individual SAM cards may be removed/replaced without service disruption to
other modules.
3. Loosen retaining screws at the top and bottom of the SAM to be replaced.
4. Use the installed ejectors to unseat the SAM from the midplane. This is done
by simultaneously pushing out on the ejectors.
5. Remove the defective SAM by pulling it straight out the chassis front.
6. Insert the replacement SAM, ensuring correct alignment with the card guides
and midplane connector.
7. Firmly press the new SAM into place so that it is fully seated with the midplane
connector. Tighten both retaining screws (finger tight only). The new card
configuration will be identical to the last configuration for the installed slot.
8. Replace the chassis front cover.
9. Return the defective SAM for repair. Contact Customer Service for an RMA
number and procedures.
