Component Description
Security Lock
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.
Switch GND 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.
AC Power Connector 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.
Power Cord Retainer Hole The power cord retainer hole is used to insert the power cord retainer to secure
the AC power cord.
Redundant Power Supply
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.
USB 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.
MGMT 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 wire-
speed. This port can be used to configure the Switch without being connected to
the network.
Console (RJ45) 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.
