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:

1Verify 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.

2Plug the power cord into the system.

3Plug 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.
