If the Switch units are free-standing, up to four

Supplying Power to the Switch
Power problems can be the cause of serious failures
and downtime in your network. Ensure that the
power input to your system is clean and free from
sags and surges to avoid unforeseen network out-
ages. 3Com recommends that you install power con-
ditioning, especially in areas prone to black outs,
power dips and electrical storms.
