14 Implementation of the DMTF Redfish API on Dell EMC PowerEdge Servers
3 Using the Redfish API on PowerEdge systems
The following tests were carried out using a PowerEdge R740 server loaded with firmware version
3.00.00.00. If a Redfish conformant server is not available, a simulated server Redfish interface is available at
the DMTF website: http://redfish.dmtf.org/redfish/v1.
3.1 Web browser access
Because REST is a web-based API, a typical web browser such as Microsoft Internet Explorer or Google
Chrome can be used for access. Start the web browser and enter the iDRAC IP address or hostname
followed by /redfish/v1/ and the Redfish root is displayed as shown in the following figure:
Accessing PowerEdge Redfish interface using a web browser
This figure illustrates the JSON response to a GET query using the Postman browser plug-in.
Each of the “@odata.id” tags can be explored individually to allow a user to drill down deeper into the Redfish
tree, but further access will prompt for authentication.
For example, Figure 4 shows how to access the Chassis collection. When the
/redfish/v1/Chassis/System.Embedded.1 URI is accessed, a pop-up box appears prompting for the entry of
an iDRAC user name and password. After these credentials are validated, more system details and additional
@odata.id tags are presented:
