Maintaining the ONS 15454 M12 (ANSI and ETSI), ONS 15454 M2 and ONS 15454 M6 Shelf
Do not leave the fan tray out of the chassis for an extended period of time because excessive heat
can damage the ONS 15454 cards.
If the fan tray does not slide all the way to the back of the shelf assembly, pull the fan tray out
and readjust the position of the air filter until the fan tray fits correctly.
On a powered-up ONS 15454, the fans start immediately after the fan-tray assembly is correctly
inserted.
