Cabling and Voltage Requirements
This section describes the cabling and voltage requirements for the
NetStacker II 12 port and 24 port hubs.
◆
Note:
You may connect network cable segments to the hub
or disconnect them while the power is on. Plugging in or
removing cables while your hub is running will not inter-
rupt the traffic or disrupt the operation of the hub.
Cabling Requirements
The cabling for connections to the NetStacker II hubs must meet or exceed the
following standards:
10Base-T
10Base-T transmission connection requires UTP (Unshielded Twisted Pair)
Category 3 cables, not to exceed 100 meters in length.
100Base-TX
100Base-TX transmission requires UTP (Unshielded Twisted Pair) Category 5
cables, not to exceed 100 meters in length. 100Base-TX requires that all wiring
and accessories meet EIA/TIA 568B specifications for proper operation. When
wiring a 100Base-TX network, make sure that the
entire
cable plant meets these
specifications.

Important
:
Some installations have UTP Category 5
cabling but do not have wall outlets and/or wiring closet
punchdown blocks that meet Category 5 requirements.
100Base-FX
100Base-FX transmission requires 62.5/125 micron graded-index multimode
fiber-optic cable with an SC connector. For details on inserting a 100Base-FX
module, see “Adding Fiber Optic Connectivity via MII” on page 11 in this
chapter.
Voltage Requirements
Voltage requirements are the same for both hubs: 100 to 240VAC, at 50 to
60Hz, with a 1.2A maximum.

Important
:
Check the AC power line voltage used in your
area.
