The following is an example list of considerations during the planning phase
specific to the 3500-PoE Switches:
■ What if power is lost to the switch?
• Power for the switch to operate (system power)
• Power for PoE devices
■ Which devices to plug into which ports and with what priorities?
• Port prioritization
• Port priority class
• Reserve watts
• Total watts available (398)
■ Which bank of 24 ports will be used?
■ Will load balancing be used?
■ Will any mini-GBICs be used and in what ports?
■ Should the 620 RPS/EPS be plugged into a different power source than
the switch it is going to back up.
