4-2 CHAPTER 4: SYSTEM POWER UP
Power Up
This section provides instructions on how to set up
and plug in your system. See Chapter 3 and
Chapter 5 for information about cabling and
configuring the Console port.
To view error messages while the system runs
power-up diagnostics, connect a terminal, a
workstation, or a PC with terminal emulation to the
system’s Console port.
To Power the Switch 3900 with the RPS
To install the Advanced Redundant Power Supply
(RPS) Type 2, follow the installation instructions that
are shipped with the RPS and its cable.
CAUTION: To prevent damage to the 3900 system
and the power supply, plug the AC power cord into
the Switch 3900 before you plug it into the
redundant power system.
To Power the Switch 3900 from the Wall Receptacle
To get your Switch 3900 powered up and ready to
operate, follow these steps:
1 Verify that the power outlet is near the system and
easily accessible. You can turn the system off only by
removing the power cord from the power source.
2 Plug the power cord into the system.
3 Plug the other end of the power cord into the power
outlet. The LEDs provide information while the system
runs power-up diagnostics.
Power-up Diagnostics
The Switch 3900 system runs diagnostic software at
power up. This software verifies that the system
works before you add it to the network.
If any component fails during power-up diagnostics,
the system either fails to power up or keeps faulty
ports off-line. To verify if any ports have failed
diagnostics, look at the system configuration display
in the Switch 3900 Administration Console. See
Chapter 4 of the SuperStack II Switch 3900 and
9300 Administration Guide.
During power up, the system status LEDs provide
information on components in the Switch 3900
system. The system and port status LEDs and the
information that they provide are shown in
Figure 4-1.
To view messages that are displayed during power-up
diagnostics, connect a terminal, workstation, or PC
that has terminal emulation to the system’s Console
port.
