Cabling and Voltage Requirements

Installation

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.
