Lantronix SISTP1040-551-LRT Install Guide 4. PoE PoH / PoE 802.3bt Mode PoH (Power over HDBaseT): HDBaseT is a global standard for distribution of ultra-high-definition video & audio, Ethernet, controls, USB and up to 100W of power over a single cable, for up to 100 meters (328 feet). For PoH information see https://hdbaset.org/. In PoH mode the switch becomes compatible with PDs supporting PoH mode (pre-bt standard). 802.3bt Mode (DIP switch 4): Type Type 1 Type 2 Type 3 Type 4 PoH Standard IEEE802.3af IEEE802.3at IEEE802.3bt IEEE802.3bt PoH PSE minimum input power 15.4 W 30 W 60 W 90 W 95 W PD minimum input power guaranteed Cable category 12.95 W 25.5 W 51W-60 W* 71W-90 W* 72 W-95 W Cat5e Cat5e Cat5e Cat5e/6 Cat5e/6 Cable length 100 m 100 m 100 m 100 m 100 m Power over 2 pairs 2 pairs 2/4 pairs 2/4 pairs 4 pairs * Extended power capability allows PD to reach upper power limit if cable length and cable resistance is known. 5. Enable PoE power cutoff when no SFP link (PSE Link Pass Thru) DIP switch 5 controls PoE power cutoff when there is no SFP link. This feature is like a media converter's Link fail Pass Through (LPT) feature. On: Enable PoE Power Cutoff function when no SFP link. 1. Set the DIP switch to ON. 2. Power ON/OFF the switch; the feature will be applied after reboot. 3. Link up SFP port. 4. Plug in PD device, the switch will deliver power to boot up the PD. 5. Remove SFP link; the Link fail event from the SFP port will pass through to remove power to the PD. 6. Link up SFP port again; PoE power is delivered to PD again. Off: Disable Power Cutoff function. 1. Switch the DIP switch to ON 2. Cycle power to the switch; the PSE LPT function will be disabled after reboot. 33841 Rev.
