Warning To prevent bodily injury when mounting or servicing this unit in a rack, you must take special
precautions to ensure that the system remains stable. The following guidelines are provided to ensure
your safety:
- This unit should be mounted at the bottom of the rack if it is the only unit in the rack.
- When mounting this unit in a partially filled rack, load the rack from the bottom to the top with the heaviest
component at the bottom of the rack.
- If the rack is provided with stabilizing devices, install the stabilizers before mounting or servicing the unit in
the rack. Statement 1006

The sequence in which the switches are first powered on might affect the switch that becomes the
stack master.
If you want a particular switch to be the stack master, power on that switch first. This switch
becomes the stack master and remains the stack master until a master re-election. After 2 minutes,
power on the other stack switches.
If you have no preference as to which switch becomes the stack master, power on all the switches in
the stack within a 1-minute timeframe. These switches participate in the stack master election.
Switches powered on after the 1-minute timeframe do not participate in the election.
Power off a switch before you add it to or remove it from an existing switch stack.
