Power Options
Table 1-3 summarizes the power options for each module. The Cisco Physical Access Gateway supports
Power over Ethernet (PoE) and DC power. All other modules support DC power only.
• The DC power connections on each module are Voltage In (VIN) and Ground (GND).
• For information on configuring PoE, see the documentation for your network switch. Your switch
must support PoE and be properly configured to use this feature with the Cisco Physical Access
Gateway.
Current Draw Requirements
Each Cisco Physical Access Control module requires a minimum amount of available power, as
described in Table 1-4. The current draw requirements listed in Table 1-4 account for inefficiencies in
power supplies and are to be used for power budgeting. The requirements do not represent actual power
usage.
