Fan Tray; 5400Zl Management Module - HP ProCurve 3500-24 Reference Manual

Fan tray

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
airflow) .
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 .
