DGS-1520 Series Gigabit Ethernet Smart Managed Switch Hardware Installation Guide Port Switch GND Security Lock Description 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 Kensington-compatible security lock can be used to connect the Switch 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.
