Chapter 5: Local Management
5-20 6H123-50 and 6H133-37 User’s Guide
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 Password
screen. To enter a new lockout time, refer to
Section 5.7.6 .
Chassis Uptime (Read-Only)
Displays the total time the chassis has been operating. The chassis uptime
is based on which interface module installed in the chassis has been
operating for the longest period of time.
Operational Mode (Selectable)
This field enables the user to set the 6H123-50 and 6H133-37 to operate
as an 802.1D switch (Switching option), as a Cabletron Systems
SecureFast switch (SFPS VLAN option) or as an 802.1Q switch.
The 12 ports located in each RJ21 interface (CONN 1 through 4 and
CONN 1 through 3) are repeater ports, and each Ethernet network, Fast
Ethernet network, Fast Ethernet Interface Module, and HSIM port(s) may
be bridged to each other.
When the operational mode is set to SFPS VLAN, the 6H123-50 and
6H133-37 act as SecureFast switches. When the Operational Mode is set
to 802.1Q switch the 6H123-50 and 6H133-37 are able to increase their
switching functionality by creating and maintaining 802.1Q Virtual LANs
(VLANs).
For details on how to select the Operation Mode, refer to Section 5.15.9 .
