The top panel provides the power input and digital input/output (DIDO) connectors:
- Power Input Terminals (PWR1, PWR2): Redundant power inputs for DC (9-48V, 3.3A max) or AC (24V, 1.2A max) power sources.
- Fault Relay Output: Provides an alarm contact for system fault conditions.
- Digital Input/Output (DIDO) Terminals: For connecting external sensors or alarms.
6. Installation
6.1 Safety Precautions
- Ensure the power source matches the switch's voltage requirements (DC 9-48V or AC 24V).
- Disconnect power before performing any installation or maintenance.
- Install the switch in a well-ventilated area to prevent overheating.
- Avoid exposing the device to moisture or extreme temperatures outside its operating range.
6.2 DIN-Rail Mounting
- Attach the DIN-rail clip to the rear of the switch using the provided screws.
- Hook the top edge of the DIN-rail clip over the top of the DIN rail.
- Push the bottom of the switch towards the DIN rail until it snaps into place.
- Ensure the switch is securely fastened to the DIN rail.
6.3 Power Connection
The IGS-6325-16T4S supports redundant power inputs. Connect your power source(s) to the terminal block on the top panel.
- Ensure the power source is off before connecting.
- Connect the positive (+) and negative (-) wires from your DC power supply to the V1+ and V1- terminals for PWR1.
- For redundant power, connect a second DC power supply to the V2+ and V2- terminals for PWR2.
- Alternatively, for AC 24V input, connect the AC wires to the V1+ and V1- (or V2+ and V2-) terminals.
- Tighten the terminal screws to secure the connections.
- Once connections are secure, turn on the power supply. The P1 and/or P2 LEDs on the front panel should illuminate.
6.4 Network Connection
- Connect Ethernet cables from your network devices (e.g., computers, servers, other switches) to the RJ45 ports (1-16) on the front panel.
- For fiber optic connections, insert compatible SFP transceivers into the SFP slots (17-20), then connect fiber optic cables.
- Verify the Link/Act LEDs for each connected port illuminate, indicating a successful connection and data activity.
7. Operation
Once installed and powered on, the IGS-6325-16T4S will begin operating. As a managed switch, its full capabilities are accessed through its management interface.
7.1 Initial Access
The switch can be accessed via its console port or through a web-based interface (if configured with an IP address).
- Console Access: Connect a serial cable from your computer to the switch's console port. Use a terminal emulator (e.g., PuTTY) with settings: 115200 bps, 8 data bits, no parity, 1 stop bit, no flow control.
- Web Interface: If the switch has a default or pre-configured IP address, connect your computer to one of the switch's Ethernet ports and access the IP address via a web browser. Refer to the Quick Installation Guide for default IP address and login credentials.
Upon successful login, you will be presented with the command-line interface (CLI) or the web management interface, allowing you to configure the switch.
