IOM Replacement
There are no field repairable items on an IOM. All user equipment connected to the defective IOM will lose ATM connectivity during replacement. Equipment connected via other IOM(s) will not have an ATM service disruption. Follow the steps below to replace an IOM:
1.Ensure that you have a replacement module.
2.Remove the chassis rear cover. The Broadmore 1700 CABB retains power; individual IOM cards may be removed/replaced without service disruption to other modules.
3.Remove and tag the cables on the IOM to be replaced.
4.Loosen retaining screws at the top and bottom of the IOM to be replaced.
5.Use the installed ejectors to unseat the IOM from the midplane. This is done by simultaneously pushing out on the ejectors.
6.Remove the defective IOM by pulling it straight out the chassis.
7.Insert the replacement IOM, ensuring correct alignment with the card guides and midplane connector.
8.Firmly press the new IOM 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.
9.Reconnect the cables to the IOM.
10.Replace the chassis rear cover.
11.Return the defective IOM for repair. Contact Customer Service for an RMA number and procedures.
