Upgrading An Srg 1.0 System To Srg 1.5; Performing The Bcm 4.0 And Srg 1.5 Upgrade - Nortel BCM 4.0 Upgrade Manual

20 Chapter 3 Post-upgrade activities
• Ensure that your system name follows the naming standards: If your system name does
not follow the naming standards for BCM 4.0, then change your system name to follow the
BCM 4.0 naming standards. For more information, see
• Configure the system time zone: Verify that the time zone including location for your system
is correct (Configuration > System > Date and Time > Time zone). BCM 4.0 includes more
time zones than previous BCM software versions. After the upgrade your system might
display an incorrect time zone, since it is not possible to upgrade the time zone setting to one
that did not exist in the previous BCM software version.
• Confirm the system is in SRG Mode (SRG systems only): To verify that your SRG 1.0
system is upgraded to an SRG 1.5 system, open Element Manager and verify that the
Survivable Remote Gateway tab is visible (Configuration > Resources > Survivable Remote
Gateway).
• Create IP filter rule: Connect to the system with Element Manager and create the IP filter
rule to allow the required port to access the BCM system (Configuration > Data Services >
NAT and Filters > Interfaces). This is required to access the system once the firewall is
enabled.
• Enable the firewall (NAT): After creating the IP filter rule, enable the firewall on the BCM
system (Configuration > Data Services > NAT and Filters > Interfaces).
• Scheduled tasks: Reprogram any scheduled tasks, such as backup, CDR, and log
management (see the BCM 4.0 Administration Guide).
• Configure SIP: If the system requires SIP, configure the required settings using Element
Manager (Configuration > Resources > Telephony Resources, then select an IP Trunk from the
list of modules).
• User accounts: Reenter the user accounts, groups, and permissions according to the
information gathered in the pre-upgrade tasks using Element Manager (Configuration >
Administrator Access > Accounts and Privileges).
• LAN: The LAN connection type is set to the default value, Auto Sense. If your system
requires another setting, you must change this value manually (Configuration > Resources >
Network Interfaces).
• WAN: If users require WAN access you must reconfigure the PPP Authentication parameters
– username and password for WAN resources. (Configuration > Resources > Network
Interfaces > Interfaces > WAN > PPP Parameters). If you need to change the associated
password, go to: Configuration > Administrator Access > Accounts and Privileges > View by
Accounts, then select the username and click Modify. This changes the password for all
instances of that username.
• DHCP: You must reconfigure the DHCP server settings for DHCP Excluded Address Range
and Client Name/Description for the Reserved Address range (Configuration > Data Services
> DHCP Server > Subnet Name > Address Ranges).
• DHCP relay agent: If your system is a relay agent, you must enable the relay of DHCP
packets on both the LAN1 and LAN2 interfaces (Configuration > Data Services > DHCP
Server > Subnets tab).
• Modem access: If users require modem access for remote management tasks, you must
configure the Modem Access Parameters (Configuration > Resources > Network Interfaces >
Interfaces > Modem).
