Subnet Mask (Modifiable)
Displays the subnet mask for the chassis. 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. The 6C105 chassis automatically uses the default subnet mask
that corresponds to the IP class that was entered in the IP address field.
Section 5.7.2 describes how to change the subnet mask from the default
value.
Chassis Date (Modifiable)
Contains a value that the chassis recognizes as the current date. When the
chassis date is modified, all interface modules installed in the chassis are
set to this date. To set a new chassis date, refer to
Section 5.7.3 .
Chassis Time (Modifiable)
Contains a value that the chassis recognizes as the current time. When the
chassis time is modified and saved, all interface modules installed in the
chassis are set to this time. To enter a new time, refer to
Section 5.7.4 .
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 5.7.5 .
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 .
NOTE
When a valid IP address is assigned, the Subnet Mask field
automatically enters the default mask that corresponds with
class of IP entered in the IP Address field. Some firmware
revisions do support changing the chassis subnet mask from
the default value. Refer to your Release Notes to ensure that
the Subnet Mask is a modifiable field.
