Installing as a Free-standing Switch
NOTE: We strongly recommend mounting the switch in a rack.
Install the switch on a flat surface if you are not installing it in a rack. The
surface must be able to support the weight of the switch and the switch
cables. The switch is supplied with four self-adhesive rubber pads.
1 Attach the self-adhesive rubber pads on each location marked on the
bottom of the switch.
2 Set the switch on a flat surface, and make sure that it has proper
ventilation by leaving 5 cm (2 inches) on each side and 13 cm (5 inches) at
the back.
Stacking Multiple N2200 Switches
You can stack N2200 switches up to 12 switches high using the QSFP ports
located on the rear of the switch. N2200 switches support stacking only with
other N2200 series switches. When multiple switches are connected together
through the stack ports, they operate as a single unit with up to 576 front
panel ports. The stack operates and is managed as a single entity.
NOTE: If you are installing a stack of switches, you need to assemble and cable the
stack before powering up and configuring it. When a stack is powered up for the
first time, the switches elect a Master Switch, which may occupy any location in
the stack. The Master LED on the front panel is illuminated on the master unit.
Creating a Switch Stack
Create a stack by connecting adjacent units using the QSFP stacking ports on
the back panel of the switch. Figure 1-6 on page 17 shows the switches
connected in a ring topology, which is the recommended topology for a stack.
1 Connect one of the QSFP cables into either of the stacking ports of the
top switch and the switch directly below it.
If necessary, use a separately purchased, longer (1 meter or 3 meter) QSFP
cable to connect the switches.
2 Repeat this process until all of the devices are connected.
3 Use the remaining stacking cable to connect the two remaining stacking
ports together so that a ring topology is assembled.
