OmniSwitch 6855 Series Hardware Users Guide March 2009 page 4-23
5 Carefully remove the retaining strap from the power supply tray. Be careful not to disrupt the
operational power supply adjacent to the power supply being hot swapped.
6 Lift the power supply that is being hot swapped out of the power supply tray and unplug its connector
cable from the PS port located in the back of the switch chassis.
Note for OS6855-14 Switches with Redundant System Power and PoE. If a power supply installed in
tray 2 (the farthest power supply tray from the chassis) requires hot swapping, the retaining strap must be
removed from tray 1 in order to gain access to the connector cables located at the rear of the chassis.
7 Install the new power supply by following the installation steps beginning at step 3 on page 4-13 of this
chapter.
Note. If the retaining strap was removed from both trays 1 and 2 in order to gain access to the connector
cables, you must reinstall the retaining straps on both trays before the hot swap installation can be
considered complete.
