Power Supply Replacement

To reduce network downtime, a power supply may be removed after it has been powered down.
When two power supplies are installed, this allows the removal of one power supply without
powering down the chassis and interrupting network traffic.
The N7 7C107 Chassis Cooling System
The N7 chassis features a removable fan tray that is accessible from the front of the unit. This unit
is hot swappable, which allows it to be replaced without powering down the chassis. The fan tray
has one LANVIEW LED located on the front of the unit. This LED indicates the status of the fan
tray (normal/fault/not installed). Refer to
states.
