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.
