    Optical ILA Component Redundancy

    The following hardware components provide redundancy on the optical ILA models:

    • Cooling system—The optical ILA has three fan modules. Each fan module is a redundant unit containing one fan. If a fan module fails and the remaining fan modules are unable to keep the optical ILA within the desired temperature thresholds, chassis alarms are raised and the optical ILA can shut down.

    • The optical ILA ships with two power supplies that provide 1+1 redundancy. If one power supply fails or is removed, the second power supply balances the electrical load without interruption and still provides 1+1 redundancy while the failing power supply is replaced.
