Power Supply Slot 1/2
Both slots come preinstalled with AC or DC power supply modules. The
slots can be outfitted with 2 DC modules, 2 AC modules, or 1 DC and 1 AC
combination for load sharing and redundancy purposes. The base model
only ships with either 2 AC or 2 DC PSUs. An additional AC or DC PSU
must be purchased separately to outfit the switch with a 1 AC + 1 DC PSU
combination.

Power Supply Modules
The 5000 Series switches ship with two power supply units preinstalled. When the primary power connection fails, the
secondary power connection will take over all the power immediately and automatically. The primary and secondary
power supply can be either AC or DC supplied, depending on the power supply module inserted, allowing for dual
redundancy.
