Powering Off the Chassis
Now that you have configured the chassis, you should power it off. To
power off the unit, do one of the following:
 For the AC AT-SBxPWRSYS1, AT-SBxPWRSYS2, and AT-
SBxPWRPOE1 PoE power supplies, disconnect the AC power
cords from the connectors on the back panel of the unit or from the
power sources.

For the AT-SBxPWRSYS1 DC power supply, turn the power
switch on the power supply to off. Refer to Figure 54 on page 121.
Be sure to power off all the power supplies in the chassis.
After powering off the chassis, do one of the following:
 To configure the second chassis, go to “Configuring the Second
Chassis” on page 303.
 If you are finished configuring both chassis, go to “Cabling the
SFP+ Slots on the Controller Cards” on page 304.
Note
Powering off the chassis to install the SFP+ transceivers for the
trunk is optional. The transceivers are hot-swappable and can be
installed while the chassis is powered on. However, Allied Telesis
recommends that both chassis be powered off when you power on
the stack for the first time.
Note
If you decide not to power off the chassis, you must reset both units
with the REBOOT command in the Privileged Exec mode after
installing the SFP+ transceivers in “Cabling the SFP+ Slots on the
Controller Cards” on page 304.
