TROUBLESHOOTING

Power and Cooling Problems

If the power indicator does not turn on when the power cord is plugged in, you may have a problem with the power outlet, power cord, or internal power supply. However, if the unit powers off after running for a while, check for loose power connections, power losses or surges at the power outlet, and verify that the fans on the unit are unobstructed and running prior to shutdown. If you still cannot isolate the problem, then the internal power supply may be defective. In this case, contact SMC Technical Support for assistance.

Installation

Verify that all system components have been properly installed. If one or more components appear to be malfunctioning (such as the power cord or network cabling), test them in an alternate environment where you are sure that all the other components are functioning properly.

In-Band Access

You can access the management agent in the switch from anywhere within the attached network using Telnet, a Web browser, or other network management software such as EliteView. However, you must first configure the switch with a valid IP address, subnet mask, and default gateway. If you have trouble establishing a link to the management agent, check to see if you have a valid network connection. Then verify that you entered the correct IP address. Also, be sure the port through which you are connecting to the switch has not been disabled. If it has not been disabled, then check the network cabling that runs between your remote location and the switch.

48-Port specifications

SMC Networks is a recognized leader in providing high-performance networking solutions, and its 48-Port Gigabit Ethernet Switch is a standout product in their lineup. Designed to cater to the demands of growing businesses and enterprise environments, this switch offers robust features and advanced technologies tailored for optimal network performance.

One of the main features of the SMC Networks 48-Port switch is its extensive port availability. With 48 Gigabit Ethernet ports, this switch allows for a substantial number of devices to connect simultaneously, making it an ideal choice for larger networks, data centers, and server farms. The switch supports auto-MDI/MDI-X functionality, which simplifies cable management by automatically detecting and configuring the appropriate cabling for each port.

The SMC Networks switch is built with Layer 2 switching capabilities, providing essential functionality such as VLAN support, link aggregation, and Spanning Tree Protocol (STP). VLANs enable network segmentation, enhancing security and performance by isolating traffic within defined groups. Link aggregation allows multiple connections to be bundled, increasing bandwidth and providing redundancy in the case of a link failure, thus ensuring uninterrupted network access.

In terms of performance, the switch boasts a non-blocking architecture that allows all ports to maintain the maximum data throughput of 1000 Mbps. This is essential for environments that handle large amounts of data traffic, such as video streaming, data backups, and cloud applications. Furthermore, the switch supports Quality of Service (QoS), allowing administrators to prioritize specific types of network traffic. This ensures that high-priority applications receive the bandwidth they need, thus providing a smooth and responsive user experience.

SMC Networks also emphasizes energy efficiency in its design. The switch is built to comply with IEEE 802.3az Energy-Efficient Ethernet standards, which reduces power consumption during periods of low traffic without compromising overall performance.

With a robust metal chassis, the 48-Port switch is not only durable but also designed for easy integration into existing network environments. It supports both rack-mount and desktop configurations, giving users flexibility in deployment.

In summary, the SMC Networks 48-Port Gigabit Ethernet Switch combines high port density, advanced switching capabilities, and energy efficiency, making it an excellent choice for modern networking needs. Its features are tailored to improve connectivity, optimize performance, and enhance network management in any professional environment.
