3. Setup
3.1 Unpacking and Inspection
Carefully remove the switch from its packaging. Inspect the unit for any signs of physical damage. Retain the packaging materials for future transport or storage.
3.2 Mounting the Switch
The Avaya 4850GTS-PWR+ is designed for rack-mounting. Use the provided rack-mount kit to secure the switch in a standard 19-inch equipment rack. Ensure adequate ventilation around the switch.
3.3 Power Connection
- Insert the 1000W field-replaceable power supply into the designated slot on the rear of the switch.
- Connect the North American power cord to the power supply and then to a grounded AC power outlet.
- If using a battery backup, connect the 1.5' battery cable to the appropriate port on the power supply and the battery unit.
- Ensure the power switch on the rear of the unit is in the OFF position before connecting to power. Once connected, switch it to ON.
3.4 Network Connections
Connect Ethernet cables from your network devices (computers, IP phones, wireless access points) to the 48 10/100/1000 PoE+ ports on the front panel. For fiber optic connections, insert compatible SFP or SFP+ transceivers into the respective ports and connect fiber optic cables.
Figure 1: Front panel of the Avaya Ethernet Routing Switch 4850GTS-PWR+. This image displays the array of 48 Gigabit Ethernet ports with Power over Ethernet Plus (PoE+) capabilities, alongside the dedicated SFP and SFP+ slots for fiber optic uplinks. The status LEDs for each port are also visible, indicating link activity and PoE status.
3.5 Initial Configuration
Access the switch's management interface via a web browser or command-line interface (CLI) using a console cable. Refer to the Avaya documentation for detailed instructions on initial IP address configuration, password setup, and basic network settings.
4. Operating
4.1 Powering On/Off
To power on the switch, ensure all connections are secure and flip the power switch on the rear panel to the ON position. To power off, flip the switch to the OFF position. For proper shutdown, it is recommended to save any configurations and gracefully shut down the system via the management interface before physically powering off.
4.2 LED Indicators
The front panel features various LED indicators for system status, port status, and PoE status. Consult the full product documentation for a detailed explanation of each LED's meaning. Generally, a solid green link LED indicates a successful connection, while a blinking LED indicates activity. PoE LEDs typically show power delivery status.
4.3 Power over Ethernet Plus (PoE+)
The 4850GTS-PWR+ supports 802.3at PoE+, providing up to 30W of power per port to connected devices such as IP phones, wireless access points, and surveillance cameras. Ensure that connected devices are PoE+ compatible. The switch automatically detects and supplies power to compliant devices.
4.4 SFP and SFP+ Ports
The SFP and SFP+ ports are used for high-speed fiber optic uplinks or stacking. Insert appropriate SFP (Gigabit) or SFP+ (10 Gigabit) transceivers into these slots. Ensure the transceivers and fiber cables match the required speed and distance specifications for your network.
5. Maintenance
5.1 Cleaning
Periodically clean the exterior of the switch with a soft, dry cloth. Ensure that the ventilation openings are free from dust and obstructions to maintain proper airflow and prevent overheating. Do not use liquid or aerosol cleaners directly on the unit.
5.2 Firmware Updates
Regularly check the Avaya support website for firmware updates. Keeping the switch firmware up-to-date ensures optimal performance, security, and access to new features. Follow Avaya's specific instructions for firmware upgrade procedures to avoid system disruption.
5.3 Environmental Considerations
Operate the switch within its specified environmental ranges for temperature and humidity. Avoid exposing the switch to direct sunlight, excessive heat, or moisture. Ensure the rack or cabinet provides adequate cooling.
6. Troubleshooting
6.1 No Power
- Verify the power cord is securely connected to both the switch and the power outlet.
- Check the power switch on the rear panel is in the ON position.
- Ensure the power outlet is functional by testing it with another device.
- Check the power supply unit for any indicator lights. If the power supply is modular, ensure it is fully seated.
6.2 No Network Connectivity
- Check the Ethernet cable connections at both the switch port and the connected device.
- Observe the port's link/activity LED. If it is off, try a different cable or port.
- Verify the connected device is powered on and configured correctly.
- If using fiber, ensure the SFP/SFP+ transceiver is correctly inserted and the fiber cable is not damaged.
6.3 PoE Issues
- Ensure the connected device is PoE+ compatible.
- Check the PoE status LED for the specific port.
- Verify that the total power budget of the switch is not exceeded.
- Try connecting the PoE device to a different port.
6.4 Management Access Issues
- Verify the IP address of the switch and your management station are in the same subnet.
- Check network connectivity between your management station and the switch.
- Ensure the correct console cable and settings are used for CLI access.
- Reset the switch to factory defaults if all else fails (consult documentation for procedure, as this will erase all configurations).
