All four fans must rotate continuously for normal operation.
If one or both fans in a fan tray fail, a message or trap is sent to the SNMP
management application to alert you.
If one or both of the fans in a fan tray operate intermittently or fail, remove and
reinsert the fan tray and secure it as described in this chapter. From this, you can
determine if the problem was simply due to a loose connection or fan tray that
was not secured to the chassis.
If problems continue, remove and replace the fan tray with a new one.
There are no user-serviceable parts in a fan tray. Do not attempt to fix a faulty fan
tray. Return the faulty fan tray to your supplier or to 3Com. Consult your purchase
records so that you can determine if the incident occurred during the warranty
period. The product warranty terms are printed in the Switch 4005 Key
Information Guide.
