System for field replaceable surge protection
A power sourcing equipment for remote powering of PoE equipment is provided including a transceiver for receiving an optical signal, a power module for receiving a power input, and a PoE device for receiving and converting the optical signal and the power input and controlling at least one remote device. A surge protector slot with a removable and field replaceable surge protector unit is provided. The removable field replaceable surge protector unit, after triggering by a surge event, is removable and replaceable with a new field replaceable surge protector unit allowing for continued surge protection without replacing the entire power sourcing equipment.
1. A system in a PoE type environment, said system comprising:
a Power Sourcing Equipment (PSE) configured to remotely power PoE equipment, said PSE receiving data and comprising:
a power module configured to receive a power input;
a PoE device controller configured to:
receive and convert said power input; and
control at least one remote device; and
a removable and field replaceable surge protector unit and a surge protector slot, wherein the surge protector slot is configured to receive the removable and field replaceable surge protector unit;
wherein said removable field replaceable surge protector unit is configured to be removable and replaceable with a new field replaceable surge protector unit, and
wherein said PSE comprises a transceiver configured to receive said data, and,
wherein said system further comprises a composite optical/power cable comprising an optical component and a power component, said composite optical/power cable being connected to said PSE such that said PoE device controller is configured to receive said data from said optical component through said transceiver and said power module is configured to receive power input from said power component through said removable and field replaceable surge protector unit.
2. The system as claimed in claim 1 , wherein said PSE further comprises a second removable and field replaceable surge protector unit and a second surge protector slot, wherein the second surge protector slot is configured to receive the second removable and field replaceable surge protector unit.
3. The system as claimed in claim 2 , wherein said second surge protector slot is located between said PoE device controller and said remote device.
4. The system as claimed in claim 1 , wherein said removable field replaceable surge protector unit includes surge protection equipment, wherein said surge protection equipment is at least one selected from the group consisting of:
silicon avalanche suppressor diode (SASD), metal oxide varsitor (MOV), filters, or gas tubes.
5. The system as claimed in claim 1 , wherein the PSE further comprises a length of conductor of at least 3 feet, between said surge protector slot and said power module.
6. The system as claimed in claim 3 , wherein the PSE further comprises a length of conductor of at least 3 feet, between said second surge protector slot and said PoE device controller.
