Quick Start Guide
Transition Networks’ SM24TBT2DPA Switch is a next-generation Ethernet switch offering full L2 features, full PoE
functionality, advanced L3 features, PoE++ per port output up to 90W. The Non-Stop PoE feature lets you upgrade
switch firmware or reboot while retaining PoE power to PDs.Note: see the Install Guide for important Safety
Warnings and Cautions, specifications, features, mounting, connections, grounding, powering, configuration,
troubleshooting, regulatory, service, warranty and tech support Information.
LED Descriptions
The front panel LEDs provide switch status checking and monitoring.
SYS (System) LED: indicates if the switch is powered up correctly or if there is a system alarm triggered.
Mode LEDs: indicate the mode of all RJ45/SFP ports on the switch. You can press the Mode/Reset button
sequentially to switch between the two different modes (Link/Activity/Speed mode and PoE mode).
Port Status LEDs: indicate the current status of each RJ45/SFP port. You can check these LEDs for port status in
different modes after changing the mode by pressing the Mode/Reset button.
Press the Mode/Reset button for less than 2 seconds to change LED mode (Link/Act/Speed Mode or PoE Mode);
you can then check the port status by reading the LED behaviors per the Install Guide.
Mode/Reset Button
Press the front panel Mode/Reset Button for a period of time to: Change Port Status LED Mode:
to read the port status correctly in the two different modes (Link/Act/Speed mode or PoE mode).
Reset the Switch: to reboot and get the switch back to the previous configuration settings saved.
The Non-Stop PoE feature lets you reboot the switch without losing PoE port power to the PDs.
Restore the Switch to Factory Defaults: to restore the original factory default settings back to the
switch. Note: See the Install Guide for LED behaviors.
Back Panel
The back panel provides for dual hot-swappable 1560W power supplies for powering the switch. The switch ships
with one power supply (780 Watts) standard; use a secondary power supply module (1560 Watts) if the full 90
Watts output is needed on all ports.
Package Contents
Check the package contents to make sure you have received the one Switch with a Power Supply installed, one
AC Power cord,asecond Power Supply (Optional), one RJ-45 to DB-9 cable, and four rubber feet.
Install SFP Modules
Do not look into laser ports. 1. Position the SFP at either install slot with the SFP label facing
correctly. 2. Carefully slide the SFP device into the slot, aligning it with the internal installation
guides. 3. Press firmly so the SFP firmly seats against the internal mating connector. 4. Attach
an appropriate cable into the SFP module port. 5. Attach the other end of the cable into the other device.

Grounding
ATTENTION: This case must be grounded. No DC input may be earth grounded. Use Isolated
Power Supply. Note: The switch is an indoor device. If it used with outdoor devices such as
outdoor IP cameras or outdoor WiFi APs, then you should install a surge protector or surge
suppressor in order to protect the switch.
Connecting to Power
CAUTION! Hazardous Area: Do Not remove this cover. Trained service people only. No serviceable components
inside. CAUTION: Hot Surfaces. WARNING: For continued protection against risk of fire, replace only with same
type and rating of fuse. Note the sticker indicating “To Keep Warranty Please Do NOT Remove”.
Connect the AC Power Cord
Warning: Risk of electrical shock. For multiple power sources: Energy hazard if both power modules are not
disconnected. Disconnect both power sources before servicing. Warning: Shock/damage hazard exists if power
supply is installed / removed while powered on.
1. Refer to the “Grounding” section above. 2. Remove the blank faceplate or use the
one open power supply slot. 3. Fasten the AC Power Supply with the slotted
retaining screw. 4. Insert the provided AC Power plug into the switch AC receptacle
(power inlet). 5. Connect the other end of the AC power cord to the AC power outlet.
6. Check that the AC OK and DC OK LEDs are lit.
Initial Switch Config via Web Browser
Power up the switch and perform the initial switch config using a web browser.
1. Connect the PC Ethernet RJ45 connector to the switch via standard Ethernet LAN cable. 2. Power up the PC to
be used for initial config. 3. Reconfigure the PC’s IP address and Subnet Mask so it can communicate with the
switch. 4. Power up the switch to be initially configured, and wait until it has finished its start-up processes.
5. Connect the PC to any port on the switch using a standard Ethernet cable; make sure the switch port LED is lit.
6. In a Web browser, enter the switch default IP address (192.168.1.77) and Subnet Mask (255.255.255.0). The
Login page should display. 7. Enter the factory default username (admin) and password (admin) on the Login
page. 8. Click the “Login” button to log into the switch. See the Web User Guide for more information.
Initial Switch Config via CLI
1. Use an RJ-45 cable to connect a terminal or PC/terminal emulator to the switch port to access the CLI.
2. Attach the RJ-45 serial port on the switch front panel to the cable for Telnet/CLI configuration. 3. Attach the
other end of the DB-9 cable to a PC running Telnet or a terminal emulation program such as HyperTerminal or
TeraTerm. 4. After powering up the switch for the first time, you can perform the initial switch configuration
using the CLI (Command Line Interface). See the CLI Reference for managing other switch features.
