Power Supplies
OmniSwitch 6900 power supplies are located at the rear of the switch chassis. Refer to page 2-2 and
page 2-3 for more information on component location. 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.
