Power Supplies

Power Supplies
OmniSwitch 6900 power supplies are located at the rear of the switch chassis. Two slots are provided. If a
second power supply is installed, it will assume a standby role.
Please note that the OS6900 does not provide an on/off switch. Connecting an installed power supply to a
power source will boot the switch. Likewise, disconnecting all installed power supplies from a power
source will power off the switch.

Airflow Direction

Power supplies are available in front-to-rear airflow or rear-to-front airflow models. Fan trays are also
direction-specific (front-to-rear or rear-to-front). When installing power supplies, they must match the
airflow direction of the fan tray. (See
