Chapter 15 Software Images
Installing Generation 2 Modules in Generation 1 Chassis
Standby Supervisor Module Bootflash Memory
When updating software images on the standby supervisor module, verify that there is enough space
available for the image . It is a good practice to remove older versions of Cisco MDS NX-OS images and
kickstart images.
To verify the space on the standby supervisor using Device Manager, follow these steps:
Step 1 Click Admin > Flash Files.
Step 2 Select the standby supervisor from the Partition drop-down list.
At the bottom of the Flash Files dialog box, you see the space used and free space.
Standby Supervisor Module Boot Alert
If a standby supervisor module fails to boot, the active supervisor module detects that condition and
generates a Call Home event and a system message and reboots the standby supervisor module
approximately 3 to 6 minutes after the standby supervisor module moves to the loader> prompt.
The following system message is issued:
%DAEMON-2-SYSTEM_MSG:Standby supervisor failed to boot up.
This error message is also generated if one of the following situations apply:
• You remain at the loader> prompt for an extended period of time.
• You do not set the boot variables appropriately.
Installing Generation 2 Modules in Generation 1 Chassis
The Generation 2 modules have the following installation restrictions:
• Supervisor-2 modules can be installed on all Cisco MDS 9500 Series Directors.
Note The Cisco MDS 9513 Director does not support Supervisor-1 modules.
• Generation 2 switching modules can be installed on all Cisco MDS 9000 Family switches, except
the Cisco MDS 9216 switch.
• Generation 1 modules can be used with Cisco MDS 9000 Family switches. However, installing
Generation 1 modules in combination with Generation 2 switching modules in the same chassis
reduces the capabilities of the Generation 2 switching modules (see the “Combining Generation 1,
Generation 2, and Generation 3 Modules” section on page 22-24).
• Generation 1 and Generation 2 switching modules can be installed on Cisco MDS 9500 Family
switches with either Supervisor-1 modules or Supervisor-2 modules.
