New features in NAC 2.5
Standard 1.0 Network Administration Center November 1998
User Guide Supplement
Support for the
Year 2000 NAC 2.5 and its operating system are designed to support the
Year 2000. With this enhancement, NAC 2.5 can operate
between the years 1970 and 2037.
The screens in NAC 2.5 are modified to allow you to enter a
two-digit year or a four-digit year when you create reports.
Note: To enter a range of years in a two-digit format, the range
must consist of the years only within the 20th century, or the
years only within the 21st century. If the range of years is
different from the current century, you must specify the years
in a four-digit format. For example, to produce a report with
data from 1998 to 1999, you enter the years as 98 and 99. To
produce a report with data from 2000 to 2001, you enter the
years as 00 and 01. However, you cannot request data in a two-
digit format for the years ranging from 1998 to 2001. To
receive this data, you must enter the years in a four-digit
format.
A report with the Year field only shows a two-digit year. For
example, the Year 2000 appears as 00 on reports, and the Year
1999 appears as 99.
The Year 2000 appears in a two-digit format (for example, 00)
in the Configuration Control transaction log. In the system error
log, the years appear in a two-digit format only within the 20th
century (for example, 99), but in a four-digit format for years in
the 21st century (for example, 2000).
Higher network
link speeds NAC 2.5 offers a higher link speed of 19,200 baud on the
network link connected with a Meridian MAX 9 (or higher)
node. In previous releases, NAC supervisors could only
configure the network link up to a speed of 9600 baud.

Standard 1.0 Network Administration Center November 1998
User Guide Supplement
Note: If NAC 2.5 is monitoring a Meridian MAX 8 (or lower)
node, the network link should configure up to 9600 baud.
NAC supervisors can configure a modem or direct network link
connection with this new speed on any of the serial ports. The
new speed improves the response time for network operations
sent over the network link.
The network link is assigned on the NAC Communication Port
Assignment screen. For more information on this screen, refer
to the Network Administration Centre (NAC) Installation Guide
(NTP 553-4011-110), “Maintenance and administration system
shutdown” chapter, “Configure NAC System” section.

Additional software codes

Additional software codes
Introduction System messages appear on your screen when you install the
software. The messages indicate the status of the installation or
upgrade procedure.
Several new lines of installation/upgrade code appear in NAC
2.5 that did not appear in earlier releases of NAC. This section
describes those lines of code.
Previous

During a new software installation, the system configures the
port devices. This code is shown in the Network Administration
Center (NAC) Installation Guide (NTP 553-4011-110),
“New software installations” chapter, page 6-17.
During this configuration process, the earlier versions of NAC
displayed the following messages:
***> Configuring port devices...(TIME)
***> Finished configuring port devices.(TIME)
If you are completing reentry point 2, 3, or 4, the following
message appears:
port_hold started.
Stream Error logging started.
netspec “tcpip” not set up.
Line printer scheduler started.
Module ID = NAC00
