Appendix A: NJ90 Specifications

The NJ90 is a 4-port, un-managed Fast Ethernet switch that fits into

most standard data port openings. The NJ90 allows up to four net-

working devices, such as computers, printers, Voice over IP (VoIP)

telephones, and scanners, to be connected to the network via one

Ethernet port.
The NJ90 needs no software to operate and requires no configura-

tion. All ports feature 10/100 Mbps auto-negotiation, which config-

ures the NJ90 for 10 Mbps or 100 Mbps connections automatically.
