5 Place the power supply (or supplies) into the power supply tray with the connector cables facing
forward.
Note. For switches using redundant chassis power with PoE, place the power supplies connected to the
PS1 and PoE1 ports side-by-side in the tray. The power supplies connected to ports PS2 and PoE2 will be
placed in an additional power supply tray later in the installation.
6 Position the power supply retaining strap over the power supplies. Insert the retaining strap’s tabs into
the notches located on the left and right sides of each power supply in order to hold each power supply
firmly in place. Be sure that the tabs are completely inserted in the power supply notches and that the end
flanges of the retaining strap fit inside the walls of the power supply tray.
7 Secure the retaining strap to the power supply tray using the attachment screws (provided).
8 Position the switch chassis immediately to the right of the power supply tray and attach the tray’s right-
front mounting flange to the left-front chassis mounting flange using two attachment screws (provided).
9 Re-attach the S-bracket to the left-rear portion of the chassis using the attachment screws removed at
step 1.
10 If no additional power supply trays are required, skip to step 16. Otherwise, refer to additional
information on redundant chassis power with PoE, below.
