PoE entry area
The PoE-supported Switch 8807/Switch 8810/Switch 8814 chassis has a PoE entry
area between the two power supply units. You can insert a PoE 3C17510 Switch
8800 PoE Entry Module into this area, and connect this module to a 3C17509
Switch 8800 External PoE Power Rack so as to import the output power of the
