Chapter 6: Configuring Switches for Stacking
Powering on the Stack
164
After configuring the master and member switches of the stack with the
previous procedures in this chapter, you are ready to cable the ports of the
stack trunk and power on the stack for the first time. (If you want to monitor
the power-on sequence, connect a terminal or PC with a terminal emulator
program to the Console port on any switch).
To power on the stack for the first time, perform the following procedure:
1. Verify that the master and all member switches are powered off.
2. Cable the ports of the stack trunk on the switches. Refer to Chapter 7,
"Cabling AT-XEM2 Line Card Ports" on page 167.
3. Power on the switches at the same time or within thirty seconds of
each other:
If the switches have AC power supplies, refer to "Powering On AT-
SBxPWRSYS2 AC Power Supplies" on page 144.
If the switches have AT-SBxPWRSYS1-80 DC Power Supplies,
power on the DC circuits and the On/Off switches on the power
supplies. For instructions on wiring the DC connector, refer to
Chapter 5, "Wiring the AT-SBxPWRSYS1-80 DC Power Supply"
on page 109.
Refer to "Power Specifications" on page 213 for the power
specifications of the switches.
