1: Introduction The Lantronix SLP Remote Power Ma nager family of products provides easy, practical, and secure soluti ons for pow er distribution, power management and load- measurement for remote equipment and bran ch AC circuits.
1: Introduction When powered on, each of the power o utl ets power sequentially with a two-second delay between each outlet. Power sequenc ing staggers the individual loa ds, eliminating the potential of a blown fuse or circuit breaker due to exce ssive in-rush current and allows circuit support for operating lo ad capacities of 80% to 90%.
2: Installation Prior to installation, refer to the following lists to ensure that you have all the items shipped with the unit as wel l as all other items required for prop er installation.
2: Installation Figure 2-1. SLP Hardw are View Output Power Status LED RS-232 Serial (RJ45) Outlet Input Current LED RJ12 Link Connectors for Optional Temperature/Humidity Sensor 10/100Base-T Ethernet.
2: Installation Always disconnect the power suppl y cord before opening to avoid e lectrical shock. Warning! High leakage current ! Earth connection is essential before connectin g supply! Warning: 208-240/230V mod els only: Outlets are not fused.
2: Installation Connecting to the Power Source Attach the power cord to the unit before con necting the unit to the power source. Each outlet powers up sequentially, with a two-second delay between each outlet, eliminating a potential blown primary fuse or circuit breaker from exce ssive in-rush current.
2: Installation The following network defaults allow unit configuration out-of-the-box through either Telnet/SSH or via a web browser: IP address: 192.
