Cisco Part Number: FPR2K-PWR-DC-350= is a Cisco Firepower 2000 Series 350W DC Power Supply
The Cisco Firepower 2100 Series is a family of four threat-focused security platforms that deliver business resiliency and superior threat defense. They offers exceptional sustained performance when advanced threat functions are enabled. These platforms uniquely incorporate an innovative dual multicore CPU architecture that optimizes firewall, cryptographic, and threat inspection functions. The series’ firewall throughput range addresses use cases from the Internet edge to the data center. Network Equipment Building Standards (NEBS)- compliance is supported by the Cisco Firepower 2130 platform. 2100 Series platforms run either the Cisco Secure Firewall ASA or Threat Defense (FMC) software. They can be deployed in both firewall and dedicated IPS modes.
The Firepower 2110 and 2120 have one fixed AC power supply that is not field-replaceable. If the power supply fails, you must get a return material authorization (RMA) for the entire chassis.
The Firepower 2130 and 2140 support two AC power supply modules so that dual power supply redundancy protection is available. The Firepower 2130 ships with one AC power supply and the Firepower 2140 ships with two AC power supplies. You can also install DC power supply modules instead of AC power on the 2130 and 2140. Facing the back of the chassis, the power supply modules are numbered left to right, for example, PSU1 and PSU2.
