Connect the equipment.Step 2. Connect to power.PoE+ access pointsPoE VoIP phoneLED Status PoE ConsiderationsThe switch prioritizes the PoE and PoE+ power that it supplies in ascending portorder (from port 1 to port 8), with a total power budget of 123 Watts. If thepower requirements for the attached powered devices (PDs) exceed the totalpower budget of the switch, the PD on the highest-numbered port is disabledto make sure that the PDs that are connected to the higher-priority, lowernumbered ports are supported first.Just because a PD is listed as an 802.3at PoE powered device does notnecessarily mean that it requires the maximum power limit of the specification.Many PDs require less power, allowing all eight PoE ports to be activesimultaneously.The following table describes the PoE classes and switch allocations.Power LED Left Port LEDs Right PoE LEDsOn1000 Mbps link PoE in useOff100 or 10 Mbps linkPoE halted (see PoETroubleshooting)Activity (blinking)No PoE use (off)No link (off)PoE Max LEDThe maximum PoE power that the switch can deliver to all attached powered devices (PDs) is123 watts total, with a maximum power to each port of 30 watts. (For more information, seePoE Considerations.)The PoE Max LED indicates the status of the PoE power that the switch can deliver to allattached PDs, as follows:Solid amber. Less than 7W of PoE power is available on the switch.Blinking amber. The PoE Max LED was lit solid in the previous two minutes.Sufficient (more than 7W of) PoE power is available on the switch (the LED is off).NETGEAR INTL LTDBuilding 3, University Technology CentreCurraheen Road, Cork, Ireland© NETGEAR, Inc., NETGEAR and the NETGEAR Logo are trademarks of NETGEAR, Inc.

Locate the two mount holes on the bottom panel of the switch.2. Mark and drill two mounting holes in the wall where you want to mount theswitch.The two mounting holes must be at a precise distance of 4.27 in. (108.4 mm) from each other.3. Insert the supplied anchors into the wall and tighten the supplied screws witha No. 2 Phillips screwdriver.Leave about 0.125 in. (4 mm) of each screw protruding from the wall so that you can insert the screws into the holes on the bottom panel.Install the Switch in a RackTo install the switch in a rack, you need the rack-mount brackets and screws that are supplied with the switch. ¾To install the switch in a rack:1. Attach the supplied mounting brackets to the side of the switch.Insert the screws provided in the product package through each bracket and into the bracket mounting holes in the switch.2. Tighten the screws with a No. 2 Phillips screwdriver to secure each bracket.3. Align the mounting holes in the brackets with the holes in the rack, and inserttwo pan-head screws with nylon washers through each bracket and into the rack.4. Tighten the screws with a No. 2 Phillips screwdriver to secure mountingbrackets to the rack.PoE TroubleshootingHere are some tips for correcting PoE problems that might occur:• Make sure that the PoE Max LED is off. If the PoE Max LED is solid amber,disconnect one or more PoE devices to prevent PoE oversubscription. Start by disconnecting the device from the highest-numbered port.• Make sure that the Ethernet cables are plugged in correctly. For eachpowered device (PD) that is connected to the switch, the corresponding right port LED on the switch lights solid green. If the right port LED lights solid amber, a PoE fault occurred and PoE halted because of one of the conditionsthat are listed in the following table.Cables and SpeedsThe following table describes the network cables that you can use for the switch connections and the speeds that these cables can support, up to 328 feet (100meters).Specifications。
