Specific Considerations for the 2910al-
PoE Switches

The following is an example list of considerations during the planning phase
specific to the 2910al 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

•

Total watts available (382)

■

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 630 RPS/EPS be plugged into a different power source than
the switch it is going to backup.
