When used in accordance with its associated documentation, it is capable of
correctly processing and/or receiving date data within and between the 20th and
21st centuries - providing all other products (for example, hardware, software, and
firmware) used with the 8275-416 properly exchange accurate date data.

Hardware
Cabling Requirements
Ethernet cables are
not
provided and must be separately purchased. You can order
them through your IBM representative.
Table 1 shows cable type and length requirements. Cable requirements depend on
the speed of the network. Cables and connecting hardware must meet the
standards specified in the ANSI/TIA/EIA 856-A or CSA T529 standards.
Table 1. Ethernet Cable Requirements
Ethernet Type Cable Requirements Max. Cable Length
10BASE-T Category 3, 4, 5, 100-ohm STP/UTP cable 100 m (328 ft)
100BASE-TX Category 5, 100-ohm STP or UTP cable and
connecting hardware 100 m (328 ft)
100BASE-FX 62.5 micron multimode fiber-optic cabling 2 km (6561 ft) at full
duplex; 412 m (1352 ft)
at half duplex
10/100BASE-TX
10BASE-T connections are MDX ports and operate correctly with standard
Category 3, 4, 5, 100-ohm UTP or STP cable and connecting hardware, as
specified in the ANSI/TIA/EIA 856-A or CSA T529 standards when
connected to MDI ports. When connecting to other MDX ports, such as
ports of other 8275-416 switches, you must use crossover cables.
Do not use telephone extension cables in 10/100BASE-TX networks. The
wire pairs in those cables are not twisted and the cables do not meet other
requirements for use in a 10BASE-T network.
For connections to 10/100BASE-TX networks, you can use only Category 5
STP or UTP cables.
100BASE-FX
For connection to 100BASE-FX networks, you can use only 62.5/125 MMF
cabling with MTRJ connectors.
