This enables extended secure access in areas outside the wiring closet (such as conference rooms) Web-based authentication Web-based authentication provides network admission control through a web browser to any host devices and operating systems STP Bridge Protocol Data Unit (BPDU) Guard A security mechanism to protect the network from invalid configurations. A port enabled for BPDU Guard is shut down if a BPDU message is received on that port. This avoids accidental topology loops STP Root Guard Prevents edge devices not in the network administrator’s control from becoming STP root nodes STP loopback guard Provides additional protection against Layer 2 forwarding loops (STP loops) DHCP snooping Filters out DHCP messages with unregistered IP addresses and/or from unexpected or untrusted interfaces. This prevents rogue devices from behaving as DHCP servers IP Source Guard (IPSG) When IPSG is enabled at a port, the switch filters out IP packets received from the port if the source IP addresses of the packets have not been statically configured or dynamically learned from DHCP snooping. This prevents IP address spoofing Dynamic ARP Inspection (DAI) The switch discards ARP packets from a port if there are no static or dynamic IP/MAC bindings or if there is a discrepancy between the source or destination addresses in the ARP packet. This prevents man-in-the-middle attacks IP/MAC/port binding (IPMB) The preceding features (DHCP snooping, IPSG, and DAI) work together to prevent Denial-of-Service (DoS) attacks in the network, thereby increasing network availability Secure Core Technol

TP-Link switch TL-RP108GE 8portový gigabitový reverzní PoE switch Easy Smart Pasivní PoE switch TL-RP108GE má sedm gigabitových PoE vstupních portů, které umožňují získávat elektrickou energii z uživatelských zásuvek pomocí PoE injektorů. Vybaven jedním PoE výstupním portem může switch napájet CPE nebo podobné zařízení pomocí Portu 8. Výstupní DC port podporuje obě napětí 5 V a 12 V a lze jej tak použít k napájení zažízení jako ONT. Díky switchingu dat a integrovaného PoE do jednoho zařízení, TL-RP108GE šetří místo, minimalizuje kabely vytížení a eliminuje potřebu vyhrazené elektrické zásuvky - snižuje tak náklady na instalaci a zjednodušuje využití PoE zařízení. 7 PoE vstupů a 1 PoE výstup 10/100/1000 Mbps RJ45 porty 1 DC výstupní port, který podporuje obě 5V a 12V přepínání napětí Odolný kovový obal je zárukou kvality a profesionálního vzhledu Inteligentní správa pomocí webového rozhraní a staženého nástroje Green technologie snižuje spotřebu elektrické energie Stránky produktu: https://www.tp-link.com/cz/business-networking/poe-switch/tl-rp108ge/ Technické specifikace HARDWARE FEATURES Standards and Protocols CSMA/CD Interface 7 Passive PoE-in RJ45 Ports: 10/100/1000Mbps Auto-Negotiation Voltage: 24/48 V (mixture is not supported) Power pin of Ethernet cable: 4/5+ 7/8- 802.3af/B, 24V DC, 48V DC 1 Passive PoE-out RJ45 Port: 10/100/1000Mbps Auto-Negotiation Voltage: depending on the input voltage of PoE-in ports Power pin of Ethernet cable: 4/5+ 7/8- 1 DC Output Port: Voltage: 5/12 V Network Media 10Base-T: UTP category 3, 4, 5 cable (maximum 100 m) EIA/TIA-568 100 Ohm STP (maximum 100 m) 100Base-TX: UTP category 5, 5e cable (maximum 100 m) EIA/TIA-568 100 Ohm STP (maximum 100 m) 1000Base-T: UTP category 5e cable (maximum 100 m) EIA/TIA-568 100 Ohm STP (maximum 100 m) Packet Forwarding Rate 11.9 Mbps Mac Address Table 4 K Jumbo Frame 16 KB Switching Capacity 16 Gbps IEEE Standards IEEE802.3ab, IEEE802.3i, IEEE802.3p IEEE802.3q, IEEE802.3x, IEEE802.3u Data Rates Ethernet: 10 Mbps (Half Duplex), 20 Mbps (Full Duplex) Fast Ethernet: 100 Mbps (Half Duplex), 200 Mbps (Full Duplex) Gigabit Ethernet: 2000 Mbps (Full Duplex) LED Indicator Power, Link/Act LED Dimensions ( W x D x H ) 6.2 × 3.9 × 1.0 in (158 × 99.1 × 25 mm) Max Power Consumption 3.98 W (with no PD connected) 18.01 W (24 V with PD connected) 32.74 W (48 V with PD connected) Max Heat Dissipation 13.57 BTU/h (with no PD connected) 61.41 BTU/h (24 V with PD connected) 111.64 BTU/h (48 V with PD connected) SOFTWARE FEATURES Quality of Service Support Port-based/802.1p/DSCP priority Support 4 priority queues Rate Limit Storm Control L2 Features IGMP Snooping V1/V2/V3 Static Link Aggregation Port Mirroring Cable Diagnostics Loop Prevention VLAN Supports up to 32 VLANs simultaneously (out of 4K VLAN IDs) MTU/Port/Tag VLAN Transmission Method Store-And-Forward OTHERS Certification FCC, CE, RoHS Package Contents TL-RP108GE Power Cord Installation Guide Rubber Feet System Requirements Microsoft Windows 98SE, NT, 2000, XP, Vista™ or Windows 7, MAC OS, NetWare, UNIX or Linux.

This enables extended secure access in areas outside the wiring closet (such as conference rooms) Web-based authentication Web-based authentication provides network admission control through a web browser to any host devices and operating systems STP Bridge Protocol Data Unit (BPDU) Guard A security mechanism to protect the network from invalid configurations. A port enabled for BPDU Guard is shut down if a BPDU message is received on that port. This avoids accidental topology loops STP Root Guard Prevents edge devices not in the network administrator’s control from becoming STP root nodes STP loopback guard Provides additional protection against Layer 2 forwarding loops (STP loops) DHCP snooping Filters out DHCP messages with unregistered IP addresses and/or from unexpected or untrusted interfaces. This prevents rogue devices from behaving as DHCP servers IP Source Guard (IPSG) When IPSG is enabled at a port, the switch filters out IP packets received from the port if the source IP addresses of the packets have not been statically configured or dynamically learned from DHCP snooping. This prevents IP address spoofing Dynamic ARP Inspection (DAI) The switch discards ARP packets from a port if there are no static or dynamic IP/MAC bindings or if there is a discrepancy between the source or destination addresses in the ARP packet. This prevents man-in-the-middle attacks IP/MAC/port binding (IPMB) The preceding features (DHCP snooping, IPSG, and DAI) work together

This prevents man-in-the-middle attacks IP/MAC/port binding (IPMB) The preceding features (DHCP snooping, IPSG, and DAI) work together
