Rear Panel Components The rear panel of this switch features an AC power connector, an outlet for an external redundant power supply, a USB port, LED indicators for USB and MGMT, an MGMT port, two console ports, an alarm port, a security lock, and a GND. Figure 2-19 Rear panel view DGS-3630-52PC Components that can be found on the rear panel of this switch are listed in the table below. Component Description AC Power Connector Redundant Power Supply USB Port MGMT Port Console Port (RJ45) Console Port (Mini-USB) Alarm Port Security Lock 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. 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 MGMT port is an IP-based, OOB port for Telnet, web, or SNMP management that operates at 10/100/1000 Mbps wire-speed. 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 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. The Mini-USB console port can be used to connect to the CLI of the Switch for configuration, management, and monitoring. The RJ45 (8 pins) Alarm port provides an external alarm detection. The Switch will send out the traps and logs when two of the pins are shorted among the pair. 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. 24
