Part number Description
NI-X-4-HSF High speed switch fabric module for 4-slot routers
NI-X-16-8-HSF High speed switch fabric module for 8- and 16-slot routers
NI-X-32-HSF High speed switch fabric module for 32-slot routers
Switch fabric modules switch packets from one interface module to another. Brocade MLXe Series routers can be congured with
multiple switch fabric modules, and described as follows:
• 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 eight switch fabric modules. Brocade MLXe Series routers ship with seven fabric modules. You
must purchase an additional switch fabric module to equip your MLXe router for redundancy.
NOTE
Brocade MLXe Series router switch fabric modules are dedicated, which means that they function properly in these routers
only. If you attempt to install a Brocade MLXe Series router switch fabric module in another Brocade device or a switch fabric
module intended for another Brocade device in a Brocade MLXe Series router, the router and switch fabric module will not
function properly.
The front panel contains two LEDs.
