Rear Panel Components The rear panel of this switch features a security lock, a GND, an AC power connector, a power cord retainer hole, and an outlet for an external redundant power supply. Figure 2-15 Rear panel view of the DGS-3130-54TS Components that can be found on the rear panel of this switch are listed in the table below. Component Description Security Lock Switch GND AC Power Connector Power Cord Retainer Hole Redundant Power Supply USB MGMT Console (RJ45) Provide a Kensington-compatible security lock to be able to connect to a secure immovable device. Insert the lock into the notch and turn the key to secure the lock. The lock-and-cable apparatus should be purchased separately. Use an electrical grounding wire and connect one end of the wire to the Switch GND and the other end of the wire to an electrical grounding point most commonly found on the Switch mounting rack itself. The AC power cord with a three-pronged AC power connector can be plugged into this receptacle to supply the Switch with 100-240 VAC power at 50-60 Hz. The power cord retainer hole is used to insert the power cord retainer to secure the AC power cord. An optional external RPS can be plugged into the RPS port found on the rear panel of switches in this series. When the internal power fails, this optional external RPS will supply power to the Switch immediately and automatically. Inserting a flash drive into the USB 2.0 Type-A port provides an additional storage space for portable firmware images and configuration files that can be copied to and from the NVRAM of the Switch. The RJ45 Management (MGMT) port is an IP-based, Out-Of-Band (OOB) port for Telnet, web, or SNMP management that operates at 10/100/1000 Mbps wirespeed. This port can be used to configure the Switch without being connected to the network. The RJ45 console port can be used to connect to the Command Line Interface (CLI) of the Switch for configuration, management, and monitoring. This port uses a special console cable (included in this package) with a DB9 interface to connect the Switch to the serial port (COM) of the PC. 23
