Mounting OS6855-14/P14 and OS6855-U10 Switches Hot-Swapping Power Supplies Hot-Swapping Power Supplies Hot swapping is supported on OS6855 switches. In order to support the hot swapping of power supplies, the switch must have: • Redundant system power or redundant PoE power (if hot swapping a PoE supply) • Power supply tray(s) installed directly behind the switch chassis Note. Hot swapping power supplies on switches without redundant system power will result in system power interruption and a loss of network connectivity. To hot swap power supplies, follow the steps below: 1 Begin by locating the power supply to be swapped, then disconnect the power cord from its power source. The system will remain operational. 2 Remove the two screws located at the top of the power cord retainer bracket. Set the retainer clip and screws aside; they will need to be reinstalled later.
