2E43-51/2E43-51R User’s Guide 5-19
Screen Lockout Time (Modifiable)
Contains the maximum number of minutes that the Local Management
application displays a module’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 module’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 2E43-51 so it operates as a an 802.1D switch
(802.1D SWITCHING), an IEEE 802.1Q switch (802.1Q SWITCHING),
or a Cabletron Systems SecureFast switch (SECURE FAST VLAN).
In 802.1D SWITCHING mode, the 12 connections on each RJ21 port
(ENET1 – ENET4) act as repeaters, and may be switched to each other
and to any Fast Ethernet Interface Module and HSIM port(s) in the
2E43-51R.
In 802.1Q SWITCHING mode, the device is able to increase its switching
functionality by creating and maintaining IEEE 802.1Q port based Virtual
LANs (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)
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.
