(7.3 kg) Switch Technology Crystal 3750G24TSS 24 Port The Crystal RCS3750G24TSS switch is a stackable Ethernet switch to which you can connect devices like IP phones, wireless access points workstations, and other network devices such as servers, routers, and other switches. You can set the 10/100/1000 ports to operate in 10 Mbps, 100 Mbps, or 1000 Mbps in full duplex. You can also set these ports for speed and duplex auto-negotiation in compliance with IEEE 802.3ab. (The default setting is auto-negotiate.) When set for auto-negotiation, the port senses the speed and duplex settings of the attached device and advertises its own capabilities. If the connected device also supports auto-negotiation, the switch port negotiates the best connection (that is, the fastest line speed that both devices support and full-duplex transmission if the attached device supports it) and configures itself accordingly.
