Changes to the switch fabric operating mode do not take effect until after a system reload.
The switch fabric modes have the following restrictions:
• The system blocks discovery of any standard switch fabric (G1) module if you have issued the
system-init block-g1-sfm command. Refer to “Blocking discovery of G1 switch fabric modules”
on page 163.
• If the system is operating in Turbo mode, standard switch fabric modules (G1) and standard
(G1) interface modules are automatically blocked.
• If there are any active G1 switch fabric modules, G2 interface modules are blocked.
• If there are any active G2 interface modules, G1 switch fabric modules are blocked.
Forcing HSF modules to operate in normal mode
This procedure requires that you restart your router.
If necessary, you can configure HSF modules to operate in normal mode using the system-init
fabric-data-mode force normal command.
Brocade(config)# system-init fabric-data-mode force-normal
Syntax: [no] system-init fabric-date-mode force-normal
If you remove the forced normal condition using the no version of this command, you must enter
the write-memory command and restart the router.
4x40G normal mode does not support line rate traffic for smaller packet sizes (64-200B).
Blocking discovery of G1 switch fabric modules
This procedure requires that you restart your router.
In a router with both standard (G1) switch fabric modules and G2 HSF modules, you can block the
discovery of the G1 switch fabric modules by entering the system-init block-g1-sfm command.
Syntax: system-init block-g1-sfm
After you enter this command, enter the write -memory command and restart the router.
Managing the cooling system
This section provides configuration, management, and monitoring information about router cooling
systems.
Configuring the cooling system
Your router is pre-configured with default settings for all cooling system parameters. Although no
initial configuration of the cooling system is necessary, you can change the settings of the following
cooling system parameters:
