Users Guide

• The Server nodes are turned on quickly, thus turning on the PCIe cards quickly.
• The powered state of PCIe cards is extended for a pre-dened time period in the following scenarios:
– After the associated server is turned o.
– After adapter discovery process is completed.
• The power-on readiness state of the cards is extended for a predened time after the discovery process. This extension
eliminates the delays for common types of power cycling scenarios. The cards continue to be in ready state awaiting node
assignment and power-up. The cards power-down after the time period expires.
.
NOTE: At the end of the time period, the PCIe cards power-down. All adapters in ride-through are also powered down
whenever the chassis door is opened.
NOTE:
• If CMC has insucient power, the CMC turns o all adapters in ride-through mode, thereby releasing all power allocated to
those adapters. If the power supply is restored, the power is reallocated to the PCIe slots. This power restoration enables
the cards to be ready for server allocation without delay.
• All external PCIE adapters powered on as shared mode is excluded from the ride-through processes. After a shared adapter
is powered on as a shared device, it remains powered on until the chassis is powered o.
Viewing PCIe Ride-through Properties Using CMC Web Interface
To view the PCIe Ride-through properties, in the left pane, click Chassis Overview → PCIe Overview. The PCIe Status page is
displayed. The General Settings section displays the following PCIe Ride-through properties status:
• Ridethrough Status — Enabled or Disabled
• Ridethrough Timeout — Indicates the time for which the Ride-through feature is enabled
Viewing PCIe Ridethrough Properties Status Using RACADM
To view the information about PCIe power ridethrough properties, enter the following command:
racadm getpciecfg –r
For more information, see the Chassis Management Controller for PowerEdge VRTX RACADM Command Line Reference Guide.
Conguring PCIe Ride-through Properties Using CMC Web Interface
To congure the PCIe Ride-through properties for CMC VRTX:
1. In the left pane, click Chassis Overview → Setup → Ridethrough.
The PCIe Ridethrough Settings page is displayed.
2. To enable or disable the PCIe Ride-through feature, select or clear the Enable PCIe Ridethrough option.
NOTE: By default, the Ride-through feature is enabled and the time period set for 300 seconds.
3. In the Timeout eld, enter the time for which the Ride-through feature to be enabled.
Type either zero (0) or a value from 60–1800 seconds. Zero indicates an innite timeout.
4. Click Apply.
Conguring PCIe Ride-through Properties Status Using RACADM
You can congure the PCIe power ride-through properties, by running the following commands:
• To disable the Ride-through feature, run the command, racadm setpciecfg ridethru –d
• To enable the Ride-through feature, run the command, racadm setpciecfg ridethru –e
• To reset the Ride-through timeout property, run the command, racadm setpciecfg ridethru –t <timeout>
