Rear panel
The rear
panel of the gigabit Ethernet switch
consist
s of
an AC
inlet power socket, which accepts input power from 100 to 240
V
AC, 50-
60
Hz
, and a
grounding screw

Note
:
1.
The gigabit Ethernet switch is a power
-
required device
which means it does not work unless power is applied. If
the network must be active at all times, consider using a
UPS (Uninterrupted Power Supply) for the gigabit Ethernet
switch. A UPS prevents network data loss or network
downtime
.
2.
In some areas, installing a surge suppression device may
also help to protect the gigabit Ethernet switch from being
damaged by an unregulated surge
or current
.
Installation
10/100/1000BASE-T
All 10/100/1000BASE
-
T ports come with auto
-negotiation
capability. They automatically support 1000BASE
-T,
100BASE
-
TX, and 10BASE
-
T networks. Users only need to
plug a working network device into one of the
10/100
/1000BASE
-
T ports, and then turn on the
gigabit
Ethernet switch. The port runs automatically in 10 Mbps,
20 Mbps, 100 Mbps, or 200 Mbps, and runs at 1000 Mbps or
2000 Mbps after negotiation with the connected device.
Cabling
Each of the 10/100/1000BASE
-T
ports uses RJ45 sockets for
the connection of unshielded twisted
-
pair cable (UTP). The
IEEE 802.3/802.3u/802.3ab Fast/Gigabit Ethernet standard
requires Category 5 UTP for 100Mbps 100BASE
-
TX. 10BASE
-
T networks can use Cat.3, 4,
or 5;
1000BASE
-
T uses 5/5e/6
UTP (see the table below). Maximum distance is 100 meters
(328 feet).

Ethernet devices
(hubs and computers, for example)

. The 10/100/1000Mbps ports
are auto
