Battery Management System

USER’S GUIDE

®

•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.

If the Client ID is changed from the Battery Management System master unit’s MAC address, the new value must be

Caution unique on the LAN. Otherwise, the DHCP or BOOTP server may act incorrectly.

–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).

For information about the Advanced settings (DHCP Cookie Is and Retry Then Stop) that directly affect how DHCP is used, see Boot Mode.
