Replacing G10 Shelf Managers (SHMMs)
CAUTION: SHMMs must always be replaced in pairs.
Failure to follow these steps can lead to corrupted shelf FRU information (such as
part number and serial number), which can render the probe offline and require
complete chassis replacement. Contact Tektronix Communications Customer
Support for assistance with G10 SHMM replacement.
Replacing the First (Standby) SHMM
DO NOT power off the probe to swap SHMMs. The probe MUST remain powered ON.
