Top Left and Top Right refer to fans in the upper front fan tray; Bottom Left and Bottom
Right refer to fans in the lower front fan tray.
To display the status of the fans in the routing matrix (TX Matrix router and all T640
routers), issue the show chassis environment command. To display the status of the
fans in a specific T640 router, issue the show chassis environment lcc lcc-number
command, where lcc-number is the chassis ID of the router and can be from 0 through 3.
NOTE: The speed of the fans in the rear fan tray of a T640 router is affected
by the temperature of the T640-SIB main board (displayed as SIB n ), not
by the temperature of the T640-SIB mezzanine board [displayed as
SIB n (B)].
For the TX Matrix Plus router (see also “TX Matrix Plus Router Cooling System” on
