Quick Start Guide
Introduction
The SM24TBT2DPB Managed Gigabit Ethernet PoE++ Switch with (24) 10/100/1000Base-T Ports + (2) 100/1000Base-X
SFP/RJ-45 Combo Ports. It comes with one PS-ACDC-1200 power supply and 19” rack mount brackets.
The SM24TBT2DPB-2XPS is the same except it comes with two PS-ACDC-1200 power supplies. Model differences are
noted where they apply.

LED Descriptions : There are several types of front panel LEDs:
SYS (System) LED indicates if the switch is powered up
correctly or if there is a system alarm triggered for
troubleshooting. Green On = switch is powered ON
correctly. Green Off = switch is not receiving power.
Red On = An abnormal state, such as exceeding
operating temperature range, was detected in the switch.
Mode LEDs indicate the mode of all RJ45/SFP ports on the switch. You can press the Mode button sequentially to switch
between the two different modes (Link/Activity/Speed mode and PoE mode).
Link/Act/Speed Green LED On = Port Status LEDs display link status, network activity and speed of each port.
RJ45 green = 1000 Mbps; amber = 10/100 Mbps. SFP green = 1000 Mbps; amber = 100 Mbps.
PoE LED Green On = RJ45 Port Status LEDs display PoE powering status of each port.
Power Supply LEDs on the back panel indicate Power Supply status. DC Green On = DC input is ready.
Red On = DC input has failed. Off = DC input is off. AC Green On = AC input is ready. Red On = AC input has failed.
Red Off = AC output is off.
Port Status LEDs: indicate the current status of each RJ45 and SFP port. Press the Mode button for less than 2 seconds
to change the LED mode to Link/Act/Speed Mode or PoE Mode. See the Install Guide for LED behavior.
Mode/Reset Button
Change LED Mode : press the button for 0~2 seconds; the SYS LED will be on green and the Port Status LED will
change based on the mode selected.
Reset the Switch : press the button for 2~7 seconds; the SYS LED will blink green, and the Port Status LEDs will all be
off.
Restore to Defaults : press the button for 7~12 seconds; the SYS LED will blink green, and all Port Status LEDs will stay
on.
Back Panel : The back panel provides two power
supply slots and an airflow opening. Caution: Be sure
to leave adequate room for the airflow opening.
Installation : Before beginning installation read the
Cautions and Warnings in the Install Guide.

Package Contents : Verify you have received one switch with one power supply included, one Saf-D adapter cable,
and one country-specific IEC adapter power cord, two 19” rack mount brackets, eight screws, one DB9F to RJ45 cable,
four rubber feet, one LTX insert card, and one printed Quick Start Guide. If ordered as SM24TBT2DPB-2XPS, there will be
two power supplies and two sets of Saf-D and power cables.
Mount the Switch in a 19-inch Rack : 1. Attach mounting brackets to both sides of chassis. 2. Insert screws and
tighten with a screwdriver to secure the brackets. 3. Position the switch in a slot in the rack, aligning the oval holes in the
brackets with the mounting holes in the rack posts. 4. Attach the brackets to the posts using screws provided. Note: See
the Install Guide for important Cautions and Warnings.
Mount the Switch on a Desk or Shelf : 1. Verify that the desk or shelf is sturdy and reliably grounded. 2. Attach the
four adhesive rubber feet to the bottom of the switch.
Install SFP Modules : See the SFP Install Guide for important information. Avoid direct exposure to laser beams.
Grounding :Case must be earth grounded. No DC input may be earth grounded.
Power Supply(s):The SM24TBT2DPB ships with one PS-ACDC-1200 power supply. The SM24TBT2DPB-2XPS ships
with two PS-ACDC-1200 power supplies. Caution: You must install the PS-ACDC-1200 Power Supply with the edge
connector down (the label facing up). If installed otherwise, the edge connector may be damaged.
The PS-ACDC-1200 can accept both high/low voltage AC and high voltage DC with an advanced Saf-D connector,
making it easy to deploy in PoE lighting in various environments. The Saf-D connector provided on the PS-ACDC-1200
has a one meter cable (25186) to convert the Saf-D to an IEC C14 Plug. Caution: use only provided power cords.
Note: See the Install Guide for additional Cautions and Warnings and Saf-D Connector information.
If using AC power: 1. Connect the Saf-D plug of the Saf-D adapter cord to the Saf-D receptacle on the switch power
supply. 2. Connect the IEC plug end of the Saf-D adapter cord to the IEC receptacle end of the power cord. 3. Plug the
power cord into an AC wall outlet. If using two power supplies, repeat steps 1-3 for the second power supply.
If using DC Power: 1. Connect the Saf-D plug of the Saf-D adapter cord to the Saf-D receptacle on the switch power
supply. 2. Cut off the receptacle end of the Saf-D adapter cord, strip the insulation on each wire back approximately 0.25"
(6mm). Twist the stranded wire ends to facilitate connection of the wires to an appropriate DC power source of your
choice, ensuring the specifications meet the designated DC power requirements. (See the Install Guide for acceptable DC
power source specifications.)
If using Digital Electricity (DE): 1. Follow the DE equipment provider's instructions to connect the Saf-D plug on the
cable to the Saf-D receptacle on the switch's power supply.
Initial Switch Config - Web Browser : After powering up the switch for the first time, you can perform the initial
switch configuration using a web browser. See the Web User Guide.
Initial Switch Config – CLI : Use an RJ-45 cable to connect a terminal or PC/terminal emulator to the switch port to
access the CLI. See the CLI Reference.
Note: See the SM24TBT2DPB Install Guide for important information on Power Supply Operating Mode Settings and
removing or replacing power supplies.
