Powering down an HPE Synergy frame that is part of a multiframe
management ring with Image Streamer
To power down an HPE Synergy frame that is part of a multiframe management ring that includes Image Streamer, use the
steps in this topic to ensure that the appliance modules are powered down in the correct order.
IMPORTANT: Powering the frame down causes the management ring to be degraded. Although management
connectivity is not lost, the management ring is no longer highly available. If the power down of the frame is only
temporary, and it is acceptable for the management ring to be in a degraded but operational state for a short time, no
further action is required. However, if the frame is expected to be powered down for an extended time, Hewlett Packard
Enterprise recommends that the CAT6A cabling be moved to bypass the powered down frame and restore the high
availability of the ring.
Procedure
1. Power down all compute modules in the frame.
2. Confirm that the HPE Synergy D3940 Storage Module power LED is off.
Power is automatically removed when the compute module is powered down.
3. Shut down the Image Streamer.
4. If it is installed in the frame, shut down the Composer.
5. Wait for several minutes for the appliance module to shut down properly.
6. Remove the frame power cables.

Powering down the compute module

Before powering down the compute module for any upgrade or maintenance procedures, perform a backup of the system and
all data. Then, shut down, as appropriate, applications and operating systems. A successful shutdown is indicated by the
system power LED displaying amber.
IMPORTANT: Always attempt a graceful shutdown before forcing a nongraceful shutdown. Application data can be lost
when performing a nongraceful shutdown of applications and the OS.
Before proceeding, verify the following:
• The compute module is in standby mode by observing that the system power LED is amber.
• The UID LED is not flashing blue.
NOTE:
◦ When the compute module is in standby mode, auxiliary power is still being provided to the system.
◦ If the UID LED is flashing blue, a remote session, or a firmware update is in progress.
