AC Power Supply

An AC-powered router has two load-sharing AC power supplies, located at the bottom rear of
the chassis, as shown in Figure 3. For information about power supply redundancy and
replaceability, see "Power Supplies" on page 16.
Figure 8 shows the power supply and Table 5 lists electrical specifications. For information
about the LED and self-test button, see "Power Supply LEDs and Self-test Button" on page 19.

After powering off a power supply, wait at least 60 seconds before turning
it back on. After powering on a power supply, wait at least 60 seconds
before turning it off.
If the router is completely powered down when you power on the power
supply, the Routing Engine boots as the power supply completes its startup
sequence. If the Routing Engine finishes booting and you need to power
down the router again, first issue the CLI request system halt command.
For more information, see "Disconnect AC Power from the Router" on page
102 or "Disconnect DC Power from the Router" on page 109.
After a power supply is powered on, it can take up to 60 seconds for
status indicators—such as LEDs on the power supply and show chassis
commands—to indicate that the power supply is functioning normally.
Ignore error indicators that appear during the first 60 seconds.
