9 Plug the power cord (supplied) into the power socket
located on the switch’s rear panel; next, plug the cord into
an easily-accessible grounded AC power source. See
“Electrical Requirements” on page 6 for more informa-
tion.
Note. Do not turn on the power supply at this time. You
will power on the switch later in the setup process.
10 If you wish to install a supplemental ground for the
switch, you may attach a type LCD8-10A-L grounding lug
to the grounding lug, located on the switch’s rear panel.
Install the type LCD8-10A-L grounding lug per manufac-
turer’s specifications.
11 If you are installing multiple switches in a rack to
form a stacked configuration, refer to “Rack Mounting
Stacked Configurations” on page 13. If you are not install-
ing a stacked configuration, continue to “Installing a Back
Up Power Supply (OS6624, OS6648, OS6600-U24)” on
page 14.
Rack Mounting Stacked Configurations
If you are rack mounting multiple switches in a stacked
configuration, be sure to place all switches in vertically-
adjacent rack positions. This will ensure that all required
stacking cables will have adequate length for the installation.
For additional instructions on rack mounting a stacked config-
uration, follow the steps below:
1 Install the rack mount flanges for all switches that are
to be included in the stacked configuration, as described
on page 11. Up to eight switches may be stacked to form a
single virtual chassis.
2 Place the next switch in the stack directly on top of the
previously installed switch.
3 Align the holes in the flanges with the holes in the
rack’s vertical posts.
4 Once the holes are aligned, insert a rack mount screw
through the bottom hole of each flange. Tighten both
screws until they are secure. Once the screws at the
bottom of each flange are secure, install the remaining two
rack mount screws. Be sure that all screws are securely
tightened.
5 Repeat steps 1 through 4 above for all remaining
switches.
6 On OS6624, OS6648, OS660-U24, and OS6600-P24
switches verify that the on/off switch for each
OmniSwitch 6600 Family switch is in the off ( O ) posi-
tion.
