The Fan Tray
The Alcatel 6000-series Fan Tray (OWA-6000-FT) promotes proper
air circulation for cooling the specialized modules in the Alcatel
Wireless LAN Switch and is required for their normal operation.
This chapter describes the general features and physical
characteristics of the fan tray, and provides instructions for
replacing the module if necessary.
Features
Built-in Redundancy
Three fans are provided in the fan tray. The module is designed to
provide for cooling, even if one fan fails. Any two operating fans
will provide enough airflow for proper cooling until the fan tray
can be replaced.
Hot Swap
Hot swapping should be performed by a trained technician. Hot
swapping allows you to replace the fan tray without having to
shut down the system. During the replacement operation, the
switch will continue to function without fans, though the
procedure must be completed within about one minute to resume
proper cooling.
