Juniper Networks EX8208 - Manual (Page 171)

To install the switch in the rack or cabinet (see Figure 50 on page 146 and Figure 51 on
page 147):
CAUTION: If you are installing more than one switch in a rack or cabinet, install the first
one at the bottom of the rack. Do not attempt to install a switch manually in an upper
position in a rack or cabinet.
1. Ensure that the rack or cabinet is placed in its permanent location and is secured to
the building.
2. Position the switch in front of the rack or cabinet, centering it in front of the adjustable
mounting brackets. Use a pallet jack if one is available.
3. With one person on each side and one person in the rear, hold the bottom of the
chassis and carefully lift it onto the adjustable mounting brackets installed in a
four-post rack or onto the power cord tray installed in a two-post rack. See Figure
49 on page 145.
WARNING: To prevent injury, keep your back straight and lift with your legs, not your
back. Do not twist your body as you lift. Balance the load evenly and be sure that your
footing is firm.
