产品介绍ProCurve 6120 系列交换机分为两种型号：----------------- 6120G/XG 6120XG产品名称的规则：以 6120 产品的 G/XG 为例，G 和 XG 都指端口速率，其中 G 表示 1Gb per second，XG 表示 10Gb per second；”/”以前的部分特指部端口速率，”/”以后的部分特指外部端口速率。前面板与端口介绍：端口 6120 G/XG端口类型端口名称 端口类型16x 1GbE Server NIC portsD1-D1616x 10GbE Server NIC ports1x 10GbE CX4C11x 10GbE CX4 or 1x 10GbE SFP+2x 10GbE XFP portsX1;X25x 10GbE SFP+ ports2x 1GbE SFP portsS1;S22x 10GbE SFP+ ports or S2S links4x 10/100/1000 RJ-45 ports1;2;3;4S2S linkI1Management PortOOBMManagement Port• 10GbE CX4—The CX4 interface requires the use of copper cabling, similar to the variety used in InfiniBand technology, and is designed to work up to a distance of 15 m. CX4 technology is an attractive solution because it has the lowest cost per port of all 10Gb interconnects, at the expense of range. CX4 has a bigger form factor than either SFP or SFP+. • 10GbE XFP ports—These 10GbE ports support SR (multi-mode fiber, 300 m) and LR (single-mode fiber, 10 km) optic transceivers based on the XFP version of the small form factor pluggable specification. XFP transceivers have a smaller form factor compared to several standards (XENPAK, X2, XPAK) that preceded it. The XFP ports support Industry Standard Servers (ISS) optics only. • 1GbE SFP ports—These 1GbE ports support SX (multi-mode fiber, 550 m) and LX (single-mode fiber, 10 km) optic transceivers based on the SFP version of the small form factor pluggable specification using an LC physical connector. These ports also support 1000BASE-T copper connections using an RJ-45 connector. The SFP ports support ISS and ProCurve optics.• 10/100/1000 RJ-45 ports—These ports support standard R...
