General Configuration Screen

Screen Lockout Time (Modifiable)

Contains the maximum number of minutes that the Local Management application displays a device’s screen while awaiting input or action from a user. For example, if the number 5 is entered in this field, the user has up to five minutes to respond to each of the specified device’s Local Management screens.

In this example, after five minutes of “idleness” (no input or action), the terminal “beeps” five times, the Local Management application terminates the session, and the display returns to the Local Management Password screen. To enter a new lockout time, refer to Section 5.7.8.

Device Uptime (Read-Only)

Displays the total time that the device has been operating.

Operational Mode (Selectable)

Allows the user to set the 2E4X-27R so it operates as an IEEE 802.1D switch (802.1D SWITCHING option), an IEEE 802.1Q switch (802.1Q SWITCHING option), or as a Cabletron Systems SecureFast switch (SECURE FAST VLAN option).

In 802.1D SWITCHING mode, the 24 ports located on the front panel, and each Fast Ethernet Interface Module, and HSIM port(s) are bridged to each other.

In 802.1Q SWITCHING mode, the 2E4X-27R is able to increase its switching functionality by creating and maintaining IEEE port based VLANs.

When the operational mode is set to SECURE FAST VLAN, the 2E4X-27R acts as a SecureFast switch. With the Cabletron Systems VLAN Manager software, the 2E4X-27R is able to increase its switching functionality by creating and maintaining Virtual LANs (VLANs).

For details on how to select the Operational Mode, refer to Section 5.7.9.

Com (Toggle)

Allows the user to enable or disable the COM port. The selection toggles between ENABLED and DISABLED. The default is ENABLED. For details about setting up the COM port, refer to Section 5.7.10.

2E49-27R, 2E48-27R specifications

Cabletron Systems 2E48-27R and 2E49-27R are powerful network switching devices that are designed to enhance the performance and reliability of network infrastructures. These devices play a critical role in ensuring seamless data transmission, making them essential for both enterprise environments and larger network setups.

One of the standout features of the Cabletron Systems 2E48-27R and 2E49-27R is their high-density design. The 2E48-27R model is equipped with 48 Ethernet ports, while the 2E49-27R includes 48 Ethernet ports along with an additional uplink capability that enhances flexibility in network connections. This high port density allows organizations to efficiently manage and connect multiple devices without taking up excessive space, making the devices ideal for environments where space is a premium.

Both models incorporate advanced switching technologies that support high throughput and low latency. This ensures that data packets are processed quickly and accurately, providing users with consistent performance and minimal delays. They also support various networking standards, including IEEE 802.3, ensuring compatibility with a wide range of devices and systems.

Another key characteristic of the 2E48-27R and 2E49-27R is their support for VLANs (Virtual Local Area Networks). This functionality allows network administrators to segment network traffic for better organization and security. By isolating different types of traffic, VLANs help to improve performance and reduce congestion, making it easier to manage network resources effectively.

In terms of management capabilities, both models offer robust features through SNMP (Simple Network Management Protocol). This allows for centralized network monitoring and management, giving administrators the tools they need to troubleshoot issues quickly and maintain optimal network performance. Additionally, the devices support easy upgrades and configuration changes, which can be crucial for adapting to evolving networking needs.

Security is another paramount feature included in the Cabletron Systems 2E48-27R and 2E49-27R. They offer access control lists (ACLs) and other security measures that help protect the network from unauthorized access and potential threats.

In summary, Cabletron Systems 2E48-27R and 2E49-27R are robust networking devices that combine high-density port configurations, advanced switching technologies, VLAN support, and comprehensive management capabilities. These features make them well-suited for high-demand network environments, ensuring efficient and secure data transmission while maximizing organizational performance.
