Brocade Communications Systems MLX Series Hardware Installation Manual page 89

When one or more NI-MLX-1GX48-T-A modules are installed in an MLX16-slot router, you must
replace the NI-X-16-FAN-EXH modules with NIBI-16-FAN-EXH-A high-speed fan modules. For more
information about high-speed fan modules, see "NIBI-16-FAN-EXH-A high-speed fan assemblies" on
page 39. If the 16-slot router is not upgraded to support NIBI-16-FAN-EXH-A modules before
NI-MLX-1GX48-T-A modules are installed, the following Syslog message is displayed.
SYSLOG: Mar 26 14:19:53:<12>R1, 48X1G modules in slots 10,11,13,16 shouldn't be running
without high speed fans.
The NIBI-16-FAN-EXH-A fan module does not ship with some Brocade MLXe-16 routers. Contact
Brocade to purchase this module.
To display information about NIBI-16-FAN-EXH-A modules installed in a 16-slot router, enter the
