OUNTING
THE
EF2211/EF2210
The EF2211/EF2210 can be mounted in a rack enclosure using four large screws (10-
32x1/2”) included with the unit. One EF2211/EF2210 fits in a single rack space.
Recommendation
For Easy Access
While not required, leave a single rack space in between the EF2211/EF2210 and
other units in your rack. This gives you easier access to the back panel.
Instructions for
Securing Power
Supply to Back of
EF2211/EF2210
• Locate the cable clamp on the back panel of the EF2211/EF2210 above the
power connector.
• Remove the screw and thread the power cord through the cable clamp.
• Attach the cable clamp to the back panel of the EF2211/EF2210 and tighten the
screw. Align the clamp so that the power cable does not interfere with the con-
nectors on the EF2211/EF2210 back panel.
• Plug in the power supply.
• We recommend that you also Ty-wrap the power supply to the rack. The purpose
of securing the power supply to the back panel is so that if the power supply were
to drop, it would pull where the cord is attached with the cable clamp and not pull
the plug out of the EF2211/EF2210.

vided with this unit.
