TECHNICAL SPECIFICATIONS

* Standard Compliance: IEEE 802.3 / 802.3ab / 802.3z / 802.3u / 802.3x
* Network Interface:
24 (RJ-45) 10/100/1000Mbps Gigabit TP
4 (SFP) 1000Mbps Gigabit fiber
Note: Port 21, 22, 23, and 24 can only be used either RJ-45 or SFP media, not both. Switch provides auto-detect function for port media selection.
* Transmission Mode:
10/100Mbps supports full- or half-duplex
1000Mbps supports full-duplex only
* Transmission Speed:
10/100/1000Mbps for TP (RJ-45)
1000Mbps only for fiber (SFP)
* Full forwarding/Filtering Packet Rate: PPS (packets per second)
1000Mbps = 1,488,000 PPS
100Mbps = 148,800 PPS
10Mbps = 14,880 PPS
* MAC Address and Self-learning: 8K MAC address
* Buffer Memory: Embedded 400KB frame buffer
* Flow Control:
IEEE 802.3x compliant for full-duplex
Backpressure for half-duplex
* Cable and Maximum Length:
TP (RJ-45) = Cat. 5 UTP cable, up to 100m
1000Base-SX SFP = Multi-mode fiber, up to 220/270/500/550m which is cable dependent
1000Base-LX SFP = Single-mode fiber, up to 10/30/50km which is SFP dependent
* Diagnostic LED:
System LED — Power
Per Port LED (RJ-45) — LINK/ACT, 10/100/1000Mbps
Per Port LED (SFP) — SFP(LINK/ACT)
* Power Requirement: AC Line
Voltage — 100~240 V
Frequency — 50~60 Hz
Consumption — 30 W
