The fan tray assembly contains the cooling fans for the interior of the 5400zl series chassis, but it excludes the
chassis power supplies, which have their own internal cooling fans . The 5406zl fan tray consists of 2 variable-
speed fans, and the 5412zl fan tray consists of 4 variable-speed fans . The fan speed is based on the sensed
ambient temperature of the chassis .
The fan tray is mounted on the left side of the chassis (from a front-view perspective), and the fans draw air
through ventilation holes to the left and blow the air out through ventilation holes to the right (side-to-side
The fan tray is hot-swappable in the Switch 5406zl and 5412zl . It can be removed and replaced without
removing power from the switch . However, the new fan tray should be installed immediately after removing the
old fan tray to avoid overheating and the automatic switch shutdown within three minutes .
In the event of an individual fan failure, an SNMP trap and event log entry are generated .
