Auto-Install Commands
Auto-Install provides automatic update of the image and configuration of
PowerConnect devices on boot up from a TFTP server as controlled by
received DHCP options. It plays a critical role in the PowerConnect offering
of touchless or low-touch provisioning, in which configuration and imaging of
a device is greatly simplified. This is highly desirable as device can be setup
with minimum interaction from a skilled technician.
In PowerConnect devices, Auto-Install provides for network-based auto-
configuration and auto-imaging. Other aspects provide support for auto-
configuration and auto-imaging from attached devices.
Auto-Install is available on Dell PowerConnect devices as per the
specification listed below.
Auto-Install features in this release include:
1 Support download of image from TFTP server using DHCP option 125.
The image update can result in a downgrade or upgrade of the firmware on
the switch or stack of switches.
2 Support for automatic download of a configuration file from a TFTP
server when the device is booted with no saved configuration file located in
designated storage. This release extends the designated storage to USB
flash drives. In previous releases, the only supported storage was the
device’s embedded flash or non-volatile memory.
3
Support for automatic download of an image from a TFTP server in the
following situations:
a
When the device is booted with no saved configuration found in the
designated storage areas.
b
When the device is booted with a saved configuration that has Auto-
Install enabled.
