5. Maintenance

5-1. Resolving No Link Condition

The possible causes for a no link LED status are as follows:

The attached device is not powered on

The cable may not be the correct type or is faulty

The installed building premise cable is faulty

The port may be faulty

5-2. Q&A

1.Computer A can connect to Computer B, but cannot connect to Computer C through the Managed Switch.

The network device of Computer C may fail to work. Please check the link/act status of Computer C on the LED indicator. Try another network device on this connection.

The network configuration of Computer C may be something wrong. Please verify the network configuration on Computer C.

2.The uplink connection function fails to work.

The connection ports on another must be connection ports. Please check if connection ports are used on that Managed Switch.

Please check the uplink setup of the Managed Switch to verify the uplink function is enabled.

3. The console interface cannot appear on the console port connection.

The COM port default parameters are [Baud Rate: 57600, Data Bits: 8,

Parity Bits: None, Stop Bit: A, Flow Control: None]. Please check the COM port property in the terminal program. And if the parameters are changed, please set the COM configuration to the new setting.

Check the RS-232 cable is connected well on the console port of the Managed Switch and COM port of PC.

Check if the COM of the PC is enabled.

4. How to configure the Managed Switch?

The “Hyperterm” is the terminal program in Win95/98/NT. Users can also use any other terminal programs in Linux/Unix to configure the Managed Switch. Please refer to the user guide of that terminal program. But the COM port parameters (baud rate/ data bits/ parity bits/ flow control) must be the same as the setting of the console port of the Managed Switch.

KGS-2416 specifications

KTI Networks KGS-2416 is a sophisticated Ethernet switch designed to meet the demands of modern networking environments. This device is particularly ideal for enterprises requiring robust performance for an expanding network infrastructure. With 24 10/100/1000Base-T ports and 2 gigabit SFP (Small Form-factor Pluggable) uplink ports, the KGS-2416 provides ample connectivity options suitable for a variety of applications, including servers, workstations, and other network devices.

One of the standout features of the KGS-2416 is its support for Layer 2 switching, which enhances data traffic management by enabling the configuration of VLANs (Virtual Local Area Networks). This capability allows network administrators to segment traffic and improve overall network performance and security. The switch supports IEEE 802.1Q VLAN tagging, allowing for up to 4096 VLANs to be configured, thus ensuring flexible network design and management.

Additionally, the KGS-2416 supports advanced traffic management features such as Quality of Service (QoS). This technology prioritizes critical network traffic, ensuring smooth and uninterrupted service for voice, video, and data applications. With support for multiple QoS standards, administrators can tailor the performance of their networks based on their specific needs.

Power over Ethernet (PoE) capability is another significant feature of the KGS-2416, allowing users to deliver both data and power over a single Ethernet cable to powered devices. This capability simplifies wiring and reduces the need for additional power supplies, making it an ideal solution for deploying IP cameras, wireless access points, and VoIP phones.

The switch is designed with an intuitive user interface that makes configuration and management hassle-free. It can be managed through both web-based GUI and command-line interface (CLI), providing flexibility for various administrative preferences. Moreover, the device supports SNMP (Simple Network Management Protocol), allowing for seamless integration into existing network management systems.

In terms of reliability, the KGS-2416 boasts features like redundant power supply options and a fanless design for silent operation. This makes it a reliable choice for environments where noise and downtime must be minimized. Overall, the KTI Networks KGS-2416 is an excellent choice for organizations looking for a feature-rich, reliable, and efficient Ethernet switch to power their networking needs.
