Chapter 6 Connecting the Cables 6-5
Note – Do not use the Serial A/LOM port for binary data transfers. To perform
anything other than ASCII transfers, use the port labeled Serial B.
6.3.1 Connecting to a Terminal Server
The serial ports on the Sun Fire V120 and Netra 120 servers are DTE ports. If you are
connecting them to other DTE ports, then the cabling between the devices you are
connecting needs to take account of this. The pinouts for the Sun Fire V120 and
Netra 120 servers’ serial ports correspond with the pinouts for the RJ-45 ports on
Cisco terminal servers. This means, for example, that if you are using a Cisco
AS2511-RJ Terminal Server, you can do either of the following:
■ Connect a roll-over cable directly to the Sun Fire V120 or Netra 120 server.
■ Connect a roll-over cable to a patch panel and use a straight-through patch cable
to connect the patch panel to the Sun Fire V120 or Netra 120 server (see
FIGURE 6-3).
Note – You do not have to use a Cisco terminal server. For other terminal servers,
check the manufacturer’s documentation to see if the pinouts of the serial ports on
the terminal server match the pinouts of the Sun Fire V120 or Netra 120 server’s
serial ports. If they do not, then write down which pins on the terminal server’s
serial ports carry the signals listed in the right-hand column in
TABLE 6-1. Then make
a roll-over cable taking each of the pins on the Sun Fire V120 or Netra 120 server’s
serial port to the correct pin on your terminal server’s serial port.
