The GW-T150WV12 hot-swappable AC power supply modules are designed to be compatible with the S5850-32S2Q, S5800-8TF12S, S5850-24T16B Ethernet Switches and T5850-32S2Q, T5800-8TF12S TAPs. You can install it without powering off the switch or disrupting the switching function.
The AC power supplies in S5800-8TF12S, S5850-24T16B Ethernet Switches and T5850-32S2Q, T5800-8TF12S TAPs give an output of 150W and support both low line voltage (100–120 VAC) and high line voltage (200–240 VAC). They provide a low-cost, simple solution to the problem of a failure of the internal power-supply of an Ethernet switch, which can result in the shutdown of that switching device and maximize the availability of the switching device.
