High speed fans requirements
• TheBigIron RX 16 requires upgrading of the rear fan modules to NI-X-16-FAN-EXH-A modules. If
the BigIron RX switch is not upgraded to support NI-X-16-FAN-EXH-A modules when 48x1G
modules are in the BigIron RX system, then the syslog message such as the following will be
displayed: SYSLOG: Mar 26 14:19:53:<12>R1, 48x1G modules in slots 10,11,13,16 must not
be running without high speed fans.
NOTE
NI-X-16-FAN-EXH-A module is not shipped by default with the BigIron RX Switch. Please contact
Brocade for purchasing this module.
• When installing 48x1G modules in the BigIron RX Switch, the operating temperature must not
exceed 30C.
To display NI-X-16-FAN-EXH-A modules in an BigIron RX Switch, enter the show chassis command.
The show chassis command displays firmware Revision A (Rev A) for NI-X-16-FAN-EXH-A modules.
Rev A indicates that the BigIron RX Switch contains the required rear fan modules to support the
48x1G modules. The rpm value threshold’s (LOW/MED/MED-HI/HI) are also displayed for rear fan
modules.
NOTE
If the BigIron RX Switch does not contain NI-X-16-FAN-EXH-A modules, the show chassis command
will not display Rev A for rear fan modules.
Switch fabric module
The switch fabric module switches uses packets from one interface module installed in a chassis to
another. The BigIron RX Series switches can be configured with switch fabric modules as
described:
• BigIron RX-4: Accommodates three switch fabric elements with two required and one
redundant for a fully loaded system. It is shipped with two switch fabric elements. You must
purchase an additional switch fabric element if you want your BigIron RX-4 equipped for
redundancy.
• BigIron RX-8: Accommodates three switch fabric elements with two required and one
redundant for a fully loaded system. It is shipped with two switch fabric elements. You must
purchase an additional switch fabric element if you want your BigIron RX-8 equipped for
redundancy.
• BigIron RX-16: Accommodates four switch fabric elements with three required and one
redundant for a fully loaded system. It is shipped with three switch fabric elements. You must
purchase an additional switch fabric element if you want your BigIron RX-16 equipped for
redundancy.
NOTE
The switch fabric elements used for the BigIron RX-4 are a different part than those used on the
BigIron RX-8, and BigIron RX-16.
The BigIron RX Series switch fabric module is dedicated, which means that it functions properly in
the BigIron RX Series chassis only. If you attempt to install a BigIron RX Series switch fabric module
in another Brocade chassis or a switch fabric module intended for another Brocade chassis in the
BigIron RX Series chassis, the chassis and switch fabric module will not function properly.
