3746-900 Procedures
3746-900 EEPROM Upgrade
EEPROM Upgrade Overview
The EEPROM of processors in the 3746-900 must be upgraded after certain:
¹
Microcode change levels (MCLs)
Note: For MCL, the EEPROM Upgrade is done automatically.
¹
Microcode change fixes (MCFs),
¹
EC installation
¹
Processor replacement.
EEPROM Upgrade/Downgrade Processing
Warning
During EEPROM Upgrade/Downgrade, Do not power OFF or IML the 3746-900.
You should be logged ON on the service processor console. If not go to “Console Use for maintenance”
on page 1-1 for logging ON and return here.
1. On the "MOSS-E VIEW" window, double click on the 3746-900 icon on which you want to work
(Note 1).
2. On the "3746-9x0 Menu" window, click on the "Change Management" option.
3. Double click on the "Upgrade/Downgrade EEPROM Code Level".
4. An "EEPROM Upgrade" window is displayed telling you that the service processor is searching the
3746-900 configuration.
5. On the "EEPROM Upgrade" window, the upgradable or downgradable processors are highlighted in
reverse video according to the preselected status of the "Upgrade" or "Downgrade" options at the top
of the window.
