System Power Switch - On/Stby - Oracle Acme Packet 4600 Hardware Installation And Maintenance Manual

Without powering down the hot-swappable Acme Packet 4600 you can exchange an
NIU by removing and replacing it. Upon removal of the NIU, the Acme Packet 4600
enters an Out-of-Service state. After you reinsert the NIU and connect to the ACLI, you
must reboot the system to return to service. This causes a soft reboot rather than a
system power cycle.
Each of the NIU front panel components are described in the following subsections.

System Power Switch - ON/STBY

The System Power switch enables you to control the power to the Acme Packet
4600. This is useful when it is desirable to shut off power to the Acme Packet 4600
without having to unplug the power cord. The Acme Packet 4600 has no other power
switches. The System Power switch, located on the front panel of the NIU, has the
following switch settings:
• STBY — when selected, the Acme Packet 4600 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.
• Standby mode (STBY) is not the same as standby state. Standby state refers to
the system state of a Acme Packet 4600 that is part of a high availability pair (HA
pair).
• ON — applies power to the Acme Packet 4600. This switch position is used during
normal operation.
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.
Note:
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.
