Hardw are Installation Guide Installing the BSDU 5.9. Connecting to BSPS for Power Management The BSDU’s front panel provides a 9-Pin DB-type port for serial RS-232 power management of the BSPS. WipLL’s WipManage manages BSPS by connecting to the BSDU through the IP network (i.e., from the BSR), and then manages BSPS through the serial connection between the BSDU and BSPS. The reason for the serial connection is that the BSPS does not support SNMP-based management, which is the basis of WipManage.
