Power supplies and the Option Cards are located in the rear of the chassis. There is a
slight difference in the rear chassis of the Acme Packet 6300 and Acme Packet 6350.
The Acme Packet 6350 has a System Power switch, which enables you to control the
power to the Acme Packet 6350. This is useful when you want to shut off power to the
Acme Packet 6350 without having to unplug the power cord. The Acme Packet 6300
does not have a System Power switch.
The System Power switch has the following switch settings:
•
STBY—when selected, the Acme Packet 6350 powers down. While the system
is in standby mode, the power supply remains active, and the fans inside of the
power supply run as necessary. The fans in the front of the chassis do not run.
This convenient feature enables the system to be shut down without having to
withdraw the power supply or disconnect the power supply cord.
Note:
Standby mode (STBY) is not the same as standby state. Standby state
refers to the system state of a Acme Packet 6350 that is part of a high
availability pair (HA pair).
•
ON—applies power to the Acme Packet 6350. This switch position is used during
normal operation.
Caution:
The System Power switch should remain in the ON position at all times.
Do not touch a System Power switch unless specifically instructed to
do so by your customer support representative or you are following
instructions in this guide.
Two LEDs are present under the System Power switch:
•
STBY—This LED is enabled when the system is in standby power mode. The LED
is inactive when the system is powered up and running.
