Powering an Appliance Event Broker Up or Down
To shut down a Solace Appliance Event Broker, and not have it automatically restart after shut down, use the power-down command.
It's also possible to remotely power on appliance event brokers using Wake On LAN (refer to Powering Up an Appliance Event Broker With WOL for details).
Powering down an appliance event broker causes a disruption in customer service. Notify the appropriate personnel to ensure that all traffic to and from appliance event brokers is stopped before powering down.
To power down to an appliance event broker, enter the following commands:
solace> enable
solace# power-down
The appliance event broker will shut down and power will be turned off.
After powering down an appliance event broker, press the (
) on/standby button to power it back up. Depending on the type of appliance event broker, the on/standby button is located on either the appliance event broker'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 event broker(refer to Powering Up an Appliance Event Broker With WOL for details).
Powering Up an Appliance Event Broker 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. Appliance event brokers are WOL‑compliant.
To generate valid Magic Packets for use with appliance event brokers, you must obtain a commercial third-party WOL tool and the target appliance event broker's management port MAC address.
When power is turned off to an appliance event brokerby 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 3530 and Solace 3560, 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 an appliance event broker turns power to the appliance event broker 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 event broker'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 event broker receives a valid Magic Packet, the Ethernet card turns on the appliance event broker to full power and starts the operating system.
