To shut down a Solace PubSub+ appliance, and not have it automatically restart after shut down, use the power-down command.
It's also possible to remotely power on Solace PubSub+ appliances using Wake On LAN (refer to Powering Up an Appliance With WOL for details).
Powering down an appliance causes a disruption in customer service. Notify the appropriate personnel to ensure that all traffic to and from appliances is stopped before powering down.
To power down to an appliance, enter the following commands:
solace> enable
solace# power-down
The appliance will shut down and power will be turned off.
After powering down an appliance, press the (
) on/standby button to power it back up. Depending on the type of appliance, the on/standby button is located on either the appliance's rear panel or front panel (in this case, use a paper clip to press the on/standby button).
You may also use Wake On LAN (WOL) to turn power back on to the appliance (refer to Powering Up an Appliance With WOL for details).
Powering Up an Appliance With WOL
Wake On LAN (WOL) is an Ethernet networking standard that allows a machine to be turned on or woken up remotely by a network message. Appliances are WOL‑compliant.
To generate valid Magic Packets for use with appliances, you must obtain a commercial third-party WOL tool and the target appliance’s management port MAC address.
When power is turned off to an appliance by the power-down Privileged EXEC command, the Ethernet card on the event broker motherboard remains powered, and listens to the network over the configured management port (either eth1 or eth2 on Solace PubSub+ 3260, 3530, and 3560, eth0 or eth1 on Solace PubSub+ 3230s, or chassis/lag1, as applicable) for a specific packet, called the Magic Packet (the management port only listens and does not reply).
Pressing the () on/standby button on a Solace PubSub+ appliance turns power to the appliance off and disables WOL. To use WOL, you must turn off power through the power-down Privileged EXEC command only.
The Magic Packet is a digital data transmission unit containing anywhere within its payload six bytes of ones (that is, hexadecimal FF FF FF FF FF FF), followed by sixteen repetitions of the target appliance’s management port Media Access Control (MAC) Address.
The Magic Packet may be sent as a broadcast packet over any network and transport layer protocol because it is only scanned for the string above and is not parsed.
When the listening appliance receives a valid Magic Packet, the Ethernet card turns on the appliance to full power and starts the operating system.
