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.

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.
