Components that can be found on the rear panel of this switch are listed in the table below.
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.
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.
LED Indicators
Located on the rear panel of this switch are LED indicators: USB and MGMT.
This LED will light solid green if a USB flash drive is plugged in.
This LED will blink green when the Switch is reading or writing data to and from
the USB drive.
This LED will be off when no USB drive is plugged into the USB port.
This LED will light solid red when a USB drive failure has been detected.
This LED will light solid green after a link to the MGMT port was successfully
established.
