Subnet Mask (Modifiable)
Displays the subnet mask for the 2E4X-27. A subnet mask “masks out”
the network bits of the IP address by setting the bits in the mask to 1 when
the network treats the corresponding bits in the IP address as part of the
network or subnetwork address, or to 0 if the corresponding bit identifies
the host. For details about how to change the subnet mask from its default
value, refer to Section 5.7.2.
Default Gateway (Modifiable)
Displays the default gateway for the 2E4X-27. This field is not defined
until an appropriate value is entered. For details about why and how to set
the default gateway, refer to Section 5.7.3.
TFTP Gateway IP Addr (Modifiable)
Displays and allows the user to set the TFTP Gateway IP address for the
2E4X-27. To set the TFTP Gateway IP address, refer to Section 5.7.4.
Device Date (Modifiable)
Contains a value that the device recognizes as the current date. To set a
new device date, refer to Section 5.7.5.
Device Time (Modifiable)
Contains a value that the device recognizes as the current time. To enter a
new time, refer to Section 5.7.6.
Screen Refresh Time (Modifiable)
Contains the rate at which the screens are updated. This setting
determines how frequently (in seconds) information is updated on the
screen. To enter a new update time, refer to Section 5.7.7.
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 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 5.7.8.
