Installation

(When you create your first user account, it will appear as though you are editing the admin account; however, you are only replacing the admin account with the new account. The admin account is not overwritten or deleted.)

Once you have created a user account, you can edit it (change the user name and/or password) or delete it. If the system contains only one user account and you delete that account, the original admin account will reappear in its place. This is because the system must always have at least one account.

To add a new user, use the arrow keys to select Edit, press Enter, then enter the new account’s user name and password in the Username and Password columns, and re-enter the password in the Password Again column to confirm the password.

To delete an existing user account, use the arrow keys to select Edit, press Enter, then delete the user name in the Username column.

To save your changes, press Esc, use the arrow keys to select Save, then press Enter.

Security Settings

The IP Configuration screen displays one option: Disable Active Management Access Profile.

Security Settings

Selecting this option will prompt you to confirm that you want to disable the active management access profile.

NOTE: This setting has no effect when Management Access Rules are not defined.

IP Configuration

The IP Configuration screen displays three menu choices: IP Address Settings, HTTP Configuration, and Network Configuration.

IP Configuration

IP Address Settings

The IP Address Settings screen allows you to set the IP information for the Switch.

IP Address Configuration

IP Address  This sets the Switch’s IP Address. The default setting is 192.168.1.254. If you change the IP address, verify that the address you enter is correct and does not conflict with another device on the network.

Subnet Mask  This combined with the IP Address defines the Switch’s network address.

Default Gateway  This defines the IP Address for the default gateway of the network.

Management VLAN  This is the ID number of the Management VLAN.

DHCP Client  The status of the DHCP client is displayed. If you want the Switch to be a DHCP client, then select ENABLE. If you want to assign an static IP address to the Switch, then enter the IP settings and select DISABLE.

HTTP

The HTTP screen allows you to set the Hyper Text Transfer Protocol server (web server) information for the Switch.

SLM224G4S specifications

The Linksys SLM224G4S is a sophisticated Layer 2 managed switch designed for businesses and institutions that demand high performance, reliability, and advanced networking features. This model stands out due to its blend of robustness and manageability, making it ideal for expanding networks.

One of the primary features of the SLM224G4S is its 24 Gigabit Ethernet ports, allowing for high-speed data transfers essential for bandwidth-intensive applications. Supporting auto-negotiation, these ports can detect the capabilities of connected devices and configure themselves accordingly, ensuring optimal performance without manual intervention. With four additional shared Gigabit SFP (Small Form-factor Pluggable) ports, this switch provides flexibility in network design and enhances scalability.

The SLM224G4S supports VLAN (Virtual Local Area Network) capabilities, which can segment network traffic to improve security and performance. This is particularly useful in environments where different departments or teams require distinct network segments for operational efficiency. By implementing VLANs, organizations can enhance their network management while isolating sensitive information from potential threats.

Quality of Service (QoS) is another critical technology integrated into the SLM224G4S. It prioritizes network traffic, ensuring that critical applications receive the bandwidth they need for optimal performance. This is particularly important for VoIP and video conferencing applications, where latency and jitter can significantly impact user experience.

The switch also features advanced Layer 2 management functionalities, including SNMP (Simple Network Management Protocol), allowing IT administrators to monitor network performance and quickly troubleshoot issues. The embedded web-based management interface makes configuration straightforward, enabling quick adjustments to settings without deep networking knowledge.

Security is a paramount consideration in today’s networking landscape. The SLM224G4S provides robust security features, including port security that limits the number of MAC addresses allowed on a port, reducing the risk of unauthorized access. Moreover, it supports802.1X port-based authentication, ensuring that only authenticated devices can connect to the network.

In summary, the Linksys SLM224G4S managed switch boasts features such as 24 Gigabit Ethernet ports, VLAN support, QoS, SNMP management, and advanced security protocols. These characteristics make it an excellent choice for businesses looking to enhance their network's performance, safety, and reliability, paving the way for seamless connectivity in today’s digital age.
