CTP150 Hot-Swap Interface Module Replacement
You can now replace the following modules on the CTP150 device without powering down the device (hot-swap);
- CTP150 4-port serial interface module (CTP150-IM-SER)
- CTP150 4-port T1E1 interface module (CTP150-IM-T1E1)
Before performing a hot-swap, be aware of the following restrictions:
- Hot-swapping works most efficiently when your interface module is the same type as the module being replaced. If your replacement interface module is a different type, you must clean up the database information for the affected slot by deleting all bundles attached to the interface module.
- You can use hot-swapping only to replace an interface module; you cannot use hot-swap to add an interface module to an empty slot.
- Hot-swapping is not supported on slot 0 because the clock distributor uses slot 0.
- For best results, close all open menu sessions before performing a hot-swap
