For the first server, I used a rail with a tab only to discover that the tab prohibited the server from being pushed in all the way. The tabs were easily removed but the server needed to be removed from the rack first.</p>\n\n<p><img alt=\"\" src=\"https://www.tunbury.org/images/dell-r640-rail.jpg\"></p>\n\n<p><img alt=\"\" src=\"https://www.tunbury.org/images/dell-r640-rail-removal.jpg\"></p>\n\n<p>First server installed</p>\n\n<p><img alt=\"\" src=\"https://www.tunbury.org/images/dell-r640-first-one.jpg\"></p>\n\n<p>The last server on the rails</p>\n\n<p><img alt=\"\" src=\"https://www.tunbury.org/images/dell-r640-last-one.jpg\"></p>\n\n<p>Front view</p>\n\n<p><img alt=\"\" src=\"https://www.tunbury.org/images/dell-r640-front-view.jpg\"></p>\n\n<p>Rear view</p>\n\n<p><img alt=\"\" src=\"https://www.tunbury.org/images/dell-r640-rear-view.jpg\"></p>\n\n<p>Cabling</p>\n\n<ul>\n <li>Yellow CAT5 for iDRAC ports</li>\n <li>Red CAT6 for 10GBase-T</li>\n</ul>\n\n<p><img alt=\"\" src=\"https://www.tunbury.org/images/dell-r640-cabled.jpg\"></p>\n\n<p>The initial iDRAC configuration was carried out using a crash cart.</p>\n\n<p><img alt=\"\" src=\"https://www.tunbury.org/images/dell-r640-idrac-config.jpg\"></p>\n\n<p>The servers are called:</p>\n\n<ul>\n <li>myrina</li>\n <li>thalestris</li>\n <li>lampedo</li>\n <li>otrera</li>\n <li>antiope</li>\n</ul>\n\n<p><img alt=\"\" src=\"https://www.tunbury.org/images/dell-r640-final.jpg\"></p>\n\n<p>We had some difficulty with the 40G uplink from the switch and we could only get the link to come up by splitting it into 4 x 10G channels, as follows.</p>\n\n<div><div><pre><code>console>enable\nconsole#configure\nconsole(config)#interface Fo1/1/1\nconsole(config-if-Fo1/1/1)#hardware profile portmode 4x10g\n</code></pre></div></div>\n\n<p>Then rebooting with <code>do reload</code>.
