Switch fabric modules switch packets from one interface module to another. Brocade MLX Series
and Brocade NetIron XMR routers can be configured with multiple switch fabric modules as
described:
• 4-slot router: Accommodates three switch fabric modules (two required and one redundant) for
a fully-loaded system. Ships with two switch fabric modules. You must purchase an additional
switch fabric module to equip your router for redundancy.
• 8-slot router: Accommodates three switch fabric modules (two required and one redundant) for
a fully-loaded system. Ships with two switch fabric modules. You must purchase an additional
switch fabric module to equip your router for redundancy.
• 16-slot router: Accommodates four switch fabric modules (three required and one redundant)
for a fully-loaded system. Ships with three switch fabric modules. You must purchase an
additional switch fabric module to equip your router for redundancy.
• 32-slot router: Accommodates and ships with eight switch fabric modules.
NOTE
Brocade MLX Series and Brocade NetIron XMR router switch fabric modules are dedicated, which
means that they function properly in these routers only. If you attempt to install a Brocade MLX
Series or Brocade NetIron XMR router switch fabric module in another Brocade device or a switch
fabric module intended for another Brocade device in a Brocade MLX Series or Brocade NetIron XMR
router, the router and switch fabric module will not function properly.
