802.3at PoE+ Support Four of the new ERS 4000 models support both 802.3af and 802.3at PoE+ This is supported on all copper ports except the copper 10/100/1000 combo ports on the Fast Ethernet models. Ports providing PoE+ ports are highlighted by an orange (Pantone 165C) line surrounding the ports. A similar red (Pantone 485C) highlight is used to identify PoE ports on ERS 4500 models. PoE plus ports supply power at up 600mA according to the 802.3at standard. The ERS 4000 PoE+ implementation supports a maximum of 54vDC. The maximum PoE+ power per port on an ERS 4000 model at the PSE is 32.4 watts. The ERS 4000 supports up to 855 watts for PoE/PoE+ when operating with one power supply installed or up to 1,855 watts for PoE/PoE+ when both power supplies are installed. Port Configurations The ERS 4800 Gigabit models support 2 SFP ports which are shared with the last 2 10/100/1000 copper ports. Plus an additional 2 SFP+ ports The SFP+ ports support either 1 Gigabit SFPs or 10Gigabit SFP+ devices Different ERS 4800 uplink combinations: Up to 2 SFP in SFP+ ports (not sacrificing any of the 10/100/1000 ports) Up to 4 SFP in SFP & SFP+ ports (if you use the SFP ports then the corresponding 10/100/1000 port is non operational) Up to 2 10 Gig SFP+ in SFP+ ports (not sacrificing any of the 10/100/1000 ports) Up to 2 10 Gig SFP+ in SFP+ ports and up to 2 SFP in SFP ports (if you use the SFP ports then the corresponding 10/100/1000 port is non operational)
