3.1 Rack Mounting

To install the 802.3at PoE+ Switch in a 19-inch standard rack, follow the
instructions described below.

Step 1: Place your 802.3at PoE+ Switch on a hard at surface, with

50/60Hz

Switch with supplied screws attached to the package. Figure
3-1 shows how to attach brackets to one side of the 802.3at
PoE+ Switch.

The device is a power-required device, which means
it will not work till it is powered. If your networks

should be active all the time, please consider using UPS
(uninterrupted power supply) for your device. It will
prevent you from network data loss or network downtime.

In some areas, installing a surge suppression device may
also help to protect your 802.3at PoE+ Switch from being
damaged by unregulated surge or current to the 802.3at
PoE+ Switch or the power adapter.

Step 6: Connect your 802.3at PoE+ Switch to 802.3af/802.3at

complied PDs and other network devices.

+

A. Connect one end of a standard network cable to the

100/1G/2.5GBASE-T RJ45 ports or 10GBASE-X SFP+ port on the
front panel of the 802.3at PoE+ Switch.

B. Connect the other end of the cable to the network devices such as

printer servers, workstations or routers, etc.

Step 7: Supply power to the 802.3at PoE+ Switch.

A. Connect one end of the power cable to the 802.3at PoE+ Switch.

B. Connect the power plug of the power cable to a standard wall

outlet.

3.2 Installing theSFP+Transceiver

The sections describe how to insert an SFP+ transceiver into an SFP+
port of the 802.3at PoE+ Switch.

The SFP+ transceivers are hot-pluggable and hot-swappable. You can
plug in and out the transceiver to/from any SFP+ port without having to
power down the 802.3at PoE+ Switch, as the Figure 3-3 shows.

It is recommended to use PLANET SFP+ on the 802.3at
PoE+ Switch. If you insert an SFP+ transceiver that is not

supported, the 802.3at PoE+ Switch will not recognize it.

- 9 -

1. Before we connect the 802.3at PoE+ Switch to the other network
device, we have to make sure both sides of the SFP+ transceivers
are with the same media type, for example, 10GBASE-SR to
10GBASE-SR; 10GBASE-LR to 10GBASE-LR.

2. Check whether the ber-optic cable type matches with the SFP+

transceiver requirement.

To connect to 10GBASE-SR SFP+ transceiver, please use the

multi-mode ber cable with one side being the male duplex LC

connector type.

To connect to 1000BASE-LR SFP+ transceiver, please use the

single-mode ber cable with one side being the male duplex LC

connector type.
