Device Uptime (Read-Only)

Displays the total time that the device has been operating.

Operational Mode (Toggle)

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

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

In 802.1Q SWITCHING mode, the device is able to increase its switching functionality by creating and maintaining IEEE port based Virtual Local Area Networks (VLANs).

When the operational mode is set to SECURE FAST VLAN, the device acts as a SecureFast switch. With the Cabletron Systems VLAN Manager software, the device is able to increase its switching functionality by creating and maintaining VLANs.

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

Com (Toggle)

This field 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.

•Local Management (LM) via a terminal or modem connection

•Uninterruptible Power Supply (UPS)

The UPS setting allows the COM port to be used to monitor an American Power Conversion Uninterruptible Power Supply (UPS).

The baud rate setting for LM is automatically sensed. For UPS, the baud rate is automatically set to 2400.

For details about how to configure the COM port, refer to Section 5.7.10.
