A gateway needs to have two doors connected to it. Each door has a reader, a maglock, a REX, and a contact closure. Can these doors be connected to a single gateway?
You need to design a 31-door, networked Cisco Physical Access Control Gateway system. Each door will be controlled by a Cisco Access Gateway, and each Cisco Access Gateway will require its own IP address. Due to the limited number of available IP addresses, the network admin has decided to implement variable-length subnet mask (VLSM) in order to better allocate the available address space. What is the most efficient subnet mask that can be used to handle the 31 IP addresses that are needed for the Cisco Access Gateways?
How should NTP be implemented in a Cisco Physical Access Control Gateway design?
When a 24 VDC fail safe lock is being used to secure a door, how should power be supplied to the lock from the control source?
