NTI RACK MOUNT CONSOLE TERMINAL WITH CONSOLE SWITCH

5.3 CPU-to-RACKMUX Ethernet Crossover Cable

In order to make a direct connection between a CPU and the ETHERNET connector of the RACKMUX, a crossover cable must be used. The cable is made with CAT5 cable terminated with RJ45 connectors and wired according to the chart below.

5.4 Serial Port Cabling

The SERIMUX simplifies cabling. The RJ45 8-pin configuration matches all SUN and Cisco RJ45 console port configurations, enabling CAT 5 cabling without pinout concerns. Three DB-25 and one DB-9 adapters come in the package. A DB-25 male, a DB- 25 female, and a DB-9 adapter support console management applications. A DB-25 male adapter provides a modem connection. See the cable adapter information that follows later in this chapter.

Note: The cable length restrictions common to RS-232 cables apply to the SERIMUX serial cable as well.

5.5 Serial Port Pinouts

The SERIMUX uses an RJ45 connector for serial ports. Pin assignments are as follows:
