NOTE: Chassis devices only – If your device has more than one power supply installed, repeat this procedure for
each power supply.
Connect the power cord supplied with the device to the power connector found on the power supply on the
front of the device.
Insert the other end into a properly grounded electrical outlet.
NOTE: The devices do not have power switches. They are powered on when the power cord is connected to the
device and to a power source.
If your installation requires a different power cord than that supplied with the device, be sure to obtain a power
cord displaying the mark of the safety agency that defines the regulations for power cords in your country. The
mark is your assurance that the power cord can be used safely with the device.
Verify proper operation by observing the LEDs:
Chassis devices – Make sure the LED on each power supply is a solid green. Also make sure that some
of the port LEDs on each module momentarily light up. The LEDs indicate that the device is performing
diagnostics. After the diagnostics are complete, the LEDs will be dark except for the ones that are
attached by cables to other devices. If the links on these cables are good and the connected device is
powered on, the link LEDs will light.
NOTE: If all of the LEDs on a module do not light up during the diagnostics, this does not indicate an error.
Only some of the LEDs are lighted during the diagnostics.
Fixed-port devices – All the port LEDs should flash momentarily, usually in sequence, while the device
performs diagnostics. After the diagnostics are complete, the LEDs will be dark except for the ones that
are attached by cables to other devices. If the links on these cables are good and the connected device
is powered on, the link LEDs will light.
For more details on specific LED conditions after system start-up, see "LEDs" on page 8-9.
5. Attaching a PC or Terminal
To assign an IP address, you must have access to the Command Line Interface (CLI). The CLI is a text-based
interface that can be accessed through a direct serial connection to the device and through Telnet connections.
The CLI is described in detail in the Command Line Interface Reference.
You need to assign a permanent IP address using the CLI. You can access the CLI by attaching a serial cable to
the Console port. After you assign an IP address, you can access the system through Telnet or the Web
Attaching a PC or Terminal Using a Serial Port
To attach a management station using the serial port:
1. Connect a PC or terminal to the serial port of the system via the (serial) console cable. The serial port is a
male DB-9 connector. Generally, a PC port will require a cable with a female DB-9 connector. Terminal
connections will vary, requiring either a DB-9 or DB-25 connector, male or female.
A console cable is provided with your switch or routing switch. Cable pin-outs and signalling for the serial
cable are shown in Figure 2.5 and Figure 2.6.
If you are using a PC for a terminal, run a terminal emulation program on the PC.
Set the terminal or PC terminal emulation program to the parameters shown below:
Baud: 9600 bps
Data bits: 8
