System Requirements
OmniSwitch 6600/7000/8800—Release 5.1.5.R04 page 5
Power Supply Requirements
The OS7000/8800 power supply requirements vary depending on the number of Network Interface (NI)
modules installed in the switch and the power redundancy requirements. Each OS7800/OS8800 chassis
contains four slots for power supplies, and the OmniSwitch 7700 chassis has three slots for power
supplies.
Note. In a fully loaded chassis configuration, the OS7700 requires a minimum of two power supplies, the
OS7800 requires three power supplies, and the OS8800 requires three power supplies. See the OmniSwitch
7700/7800 Hardware User Guide and the OmniSwitch 8800 Hardware User Manual for more informa-
tion about power supply requirements.
Upgrading to 5.1.5.R04
Instructions for upgrading to 5.1.5.R04 (image files, Miniboot, Bootrom, FPGA) are available on the
Customer Support website along with the 5.1.5.R04 software (eservice.ind.alcatel.com).
Note. Failure to follow the upgrade instructions correctly can permanently damage CMM hardware.
Note. Once you have upgraded to 5.1.5.R04, downgrading the system must be done on each CMM sepa-
rately.
Merging OS6600 Stacks
You cannot merge two OS6600 stacks (i.e., virtual chassis) unless they are running identical versions of
software. Alcatel recommends the following steps to merge two separate stacks:
1 Upgrade one or both (if necessary) stacks so they are running the same software.
2 Use the copy working certified flash-syncro command on the stacks you have upgraded.
3 Confirm both stacks are running the same software with the show microcode loaded command.
4 Confirm that all switches (modules) in both stacks have unique slot numbers by viewing the Slot
Indicator LEDs. Renumber any duplicate slot numbers by using the procedures outlined in the
OmniSwitch 6600 Series Getting Started Guide.
5 Connect the two stacks together into one stack. Refer to the OmniSwitch 6600 Series Getting Started
Guide for cabling guidelines.
6 Use the show stack topology command to confirm that the stacks have been successfully merged.
