General Rack-Mounting Guidelines
If you will be rack-mounting your switch(es), refer to the important guidelines below before installing.
• It is recommended that two people install the switch assembly on the rack—one person to hold the
chassis and position it on the rack, and a second person to secure the chassis to the rack using
attachment screws. (Please note that Alcatel-Lucent does not provide rack-mount screws. Use the
screws supplied by the rack vendor.)
• To prevent a rack from becoming top heavy, it is recommended that you install heavier equipment at
the bottom of the rack, whenever possible.
• Review page 4-3 for recommended chassis clearances before installing.
• If you are installing the switch on a relay rack, be sure to install and secure the rack per the rack
manufacturer’s specifications.
Positioning the Power Supply Tray(s)
When rack mounting the switch, the power supply tray is positioned at the left side of the unit assembly by
default. This allows the chassis and power supply assembly to span the full width of the rack.
If both redundant chassis power and Power over Ethernet (PoE) are to be used an additional power supply
tray must be mounted immediately behind the switch chassis. Refer to the table on page 4-4 for additional
power supply requirements.
Detailed instructions for installing power supplies and power supply trays are provided in this section.
Installation
1 To mount a single chassis in a rack, begin by removing the S-bracket located at the left-rear portion of
the switch chassis. Once removed, set the bracket and attachment screws aside; they will need to be re-
installed later.
Remove the side S-bracket from the chassis
by removing the two chassis attachment
screws.
Set the bracket and attachment screws aside.
