Firmware Upgrade Procedures
Firmware upgrades to an NCC 2020 may be done in two ways:
Replacing the socketed EEPROMS which hold the node management and CSU firmware.
Using either Access Manager 2000 or Node Manager to download new code to the module.
The TAC 2010 CSU firmware in an NCC 2020 resides in the EEPROM in socket U11.
The NCC 2020 management firmware resides in the EEPROM in socket U22.
Verilink offers upgrade kits which include one each of these two integrated circuits. Contact Verilink Technical Support if you require a firmware upgrade.
Network Management Programs
Both Access Manager 2000 and Node Manager offer download procedures which may be used to upgrade either the CSU or network management portions of an NCC 2020.
For details on using Access Manager 2000 to upgrade an NCC 2020 or the other modules it controls, refer to the Access Manager 2000 User Manual.
