Installing and Setting Up the Unit

Grounding

Reliable grounding of this equipment must be maintained. Particular attention should be given to electrical connections when connecting to a power strip, rather than direct connections to the electrical outlet.

Connecting Ethernet Devices

For optimum performance, the Ethernet segments connected to the NH2025-10 must be configured carefully. Generally, the segments should be configured so that machines on a given port communicate primarily among themselves; that is, most traffic does not need to cross the switch. However, this is not the best configuration for certain situations.

Connecting Your Network

The cable connections to the 10/100BaseTX ports can be UTP or STP Category 3 and above, and cable length is limited to 100 meters on each port. STP cable carries a higher quality of signal and is less sensitive to environmental noise.

The RJ-45 ports of the switch are defined as MDI-X ports.

The 10/100BaseTX ports on the NH2025-10 are designed to be connected directly to a workstation, using a standard straight through patch cable. In order to cascade switches or connect a hub to the switch, a crossover cable must be used.
