2.2.4 Connecting External I/O Cables
Front panel ports are typically used for maintenance and troubleshooting purposes
in installed and running systems. External I/O cables are connected to the Sun Netra
CP3250 blade server or to the Netra CP32x0 rear transition module when a rear
transition module is used.
To connect each of these following cables:
■ For Ethernet connections, Category 5e or better, network cable is required.
Connect one end of the Ethernet cable to a suitable 10/100/1000 MBASE-T
Ethernet switch and the other end to one of the Ethernet ports on the Sun Netra
CP3250 blade server or the Netra CP32x0 ARTM.
■ Attach asynchronous serial I/O cables from serial communication devices to the
RJ-45 serial ports on the Sun Netra CP3250 blade server or Netra CP32x0 ARTM.
2.2.4.1 Connecting Cables to a System Console Running the Solaris
OS
1. Connect a RJ-45 style serial cable to the serial console port on the front panel of
the Sun Netra CP3250 blade server (
FIGURE 2-4) or the Netra CP32x0 rear
transition module.
Serial access (both front and rear) is through the same serial interface controller. If
both ports are connected at the same time, console input and output can be
performed through both, however, this configuration is not recommended. If both
access interfaces are not connected at the same time, console input/output can be
performed through NetConsole session via the ShMM.
2. Connect the other end of the serial cable to the serial port of the system serving
as the serial console.
