Cabletron Systems 2E48-27R Benutzerhandbuch

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 

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).

Com (Toggle)

Allows the user to enable or disable the COM port. The selection toggles 
between ENABLED and DISABLED. The default is ENABLED. For
