NOTE
Do not connect the switch to the network until the IP address is correctly set.
Providing power to the switch
Perform the following steps to provide power to the switch.
1. Connect the power cords to both power supplies and then to power sources on separate circuits to
protect against AC failure. Ensure that the cords have a minimum service loop of 6 in. available and
are routed to avoid stress.
Connecting a power cord turns the switch on. The power supply has two LEDs, one for AC status
and one for DC status. Both LEDs go green within a second of power being applied. The Power
Status LED on the portside turns green as soon as either power supply LED is green. The status
LED is amber only until FOS is loaded and then it turns green. The status LED is green while POST
is running.
2. After POST is complete, verify that the Brocade 7840 power and status LEDs of the switch are green.
Connecting to the switch using the serial connection
Perform the following steps to log in to the switch through the serial connection.
1. Verify that the switch has completed POST. When POST is complete, the port status and switch
power and status LEDs return to a standard healthy state.
2. Connect the serial cable to the serial port on the switch and to an RS-232 serial port on the
workstation.
If the serial port on the workstation is RJ-45 instead of RS-232, remove the adapter on the end of the
serial cable and insert the exposed RJ-45 connector into the RJ-45 serial port on the workstation.
3. When the terminal emulator application stops reporting information, press Enter to display the login
prompt.
4. Log in to the switch as admin, using the default password: password. You are prompted to change
the default passwords at initial login.
5. Configure the application as follows:
• In a Windows environment:
Parameter
Value
Bits per second 9600
Databits 8
Parity None
Stop bits 1
Flow control None
• In a UNIX environment using TIP, enter the following string at the prompt:
tip /dev/ttyb -9600.
