2
If you install thirteen or more NI-MLX-1Gx48-T-A modules are installed in your router, you will need a
minimum of five power supplies. You can achieve 5+3 power redundancy by installing an additional
three power supplies.
When one or more NI-MLX-1GX48-T-A modules are installed in the Brocade MLX-16 router, you
must replace the NI-X-16-FAN-EXH fan modules with NIBI-16-FAN-EXH-A high speed fan modules.
Refer to “Installing NIBI-16-FAN-EXH-A fan assemblies” on page 76.
If the Brocade MLX-16 is not upgraded to support NIBI-16-FAN-EXH-A modules when
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.
This message is displayed at bootup, or when the NI-MLX-1Gx48-T-A module is inserted in the
router.
When installing NI-MLX-1Gx48-T-A modules, you must upgrade the software on all installed
interface modules and management modules to the appropriate software release. For more
information refer to the Multi-Service IronWare Software Release 05.2.00 for Brocade MLX Series
and Brocade NetIron Family. For more information on upgrading the software, refer to the
Multi-Service IronWare Software Upgrade Guide.
