Installing a Compact Switch
You can use this application to calculate the power supply requirements for a specific PoE configuration. The
results show output current, output power, and system heat dissipation.

Procedure
Step 1
Connect one end of the cable to the switch PoE port.
Step 2
Connect the other end of the cable to an RJ-45 connector on the other device. The port LED turns on when
both devices have established link.
The port LED is amber while STP discovers the topology and searches for loops. This process takes about
30 seconds, and then the port LED turns green. If the LED is off, the other device might not be turned on,
there might be a cable problem, or there might be a problem with the adapter in the other device.
Step 3
Reconfigure and reboot the connected device, if needed.
Step 4
Repeat Steps 1 through 3 to connect each device.
Note
10/100/1000 Ethernet Port Connections
The switch 10/100/1000 port configuration changes to operate at the speed of the attached device. If the
attached ports do not support autonegotiation, you can manually set the speed and duplex parameters.
Connecting devices that do not autonegotiate or that have the speed and duplex parameters manually set can
reduce performance or result in no linkage.
To maximize performance, choose one of these methods for configuring the Ethernet ports:
Voltages that present a shock hazard may exist on Power over Ethernet (PoE) circuits if interconnections
are made using uninsulated exposed metal contacts, conductors, or terminals. Avoid using such
interconnection methods, unless the exposed metal parts are located within a restricted access location
and users and service people who are authorized within the restricted access location are made aware
of the hazard. A restricted access area can be accessed only through the use of a special tool, lock and
key or other means of security. Statement 1072
Category 5e and Category 6 cables can store high levels of static electricity. Always ground the cables
to a suitable and safe earth ground before connecting them to the switch or other devices.
Noncompliant cabling or powered devices can cause a PoE port fault. Use only standard-compliant
cabling to connect Cisco prestandard IP Phones and wireless access points, IEEE 802.3af, or 802.3at
(PoE+) compliant devices. You must remove any cable or device that causes a PoE fault.
Many legacy powered devices, including older Cisco IP phones and access points that do not fully
support IEEE 802.3af, might not support PoE when connected to the switches by a crossover cable.
