USER’S GUIDE
Battery Management System
36
• Three settings are available for all Boot mode selections, except
Manual, to identify the Management Card in BOOTP or DHCP
communication:
– Vendor Class: Uses APC, by default.
– Client ID: Uses the Battery Management System’s MAC address,
by default.
– User Class: Uses the Battery Management System’s application
firmware module type, by default. For example, a Battery
Management module sets the User Class to BMS-HVA.
• Two settings are available if BOOTP only is the Boot mode selection:
– Retry Then Fail: Defines how many times the Battery Management
System will attempt to discover a BOOTP server before it stops (4,
by default).
– On Retry Failure: Defines what TCP/IP settings will be used by the
Battery Management System when it fails to discover a BOOTP
server (Use Prior Settings, by default).
Caution
If the Client ID is changed from the Battery Management
System master unit’s MAC address, the new value must be
unique on the LAN. Otherwise, the DHCP or BOOTP server
may act incorrectly.
For information about the Advanced settings (DHCP Cookie Is
and Retry Then Stop) that directly affect how DHCP is used, see
Boot Mode.
