This is shame because they were also sold for the 3048, but the replacement 9k switche for the 3048 and FEXes do not offer a sleeve. We will have to see if they run too hot and need a sleeve... and who offers such a product.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-3266263034124005485.post-20810099606905048722015-08-09T01:17:03.314+01:002015-08-09T01:17:03.314+01:00I was also surprised to see no cutouts for power c...I was also surprised to see no cutouts for power cables.<br /><br />"since PDU's are installed at the back, it means you have to used up 1U underneath it to pass your cables back through the rack"<br /><br />Well, in fairness to the duct, it didn't introduce that particular problem. FEX power cords are going to need to find their way around to the back of the cabinet somehow. The installations I'm familiar with don't require any extra RU. The power cables go through a bristled thing off to the side of the vertical posts in the cabinet.<br /><br />Yeah, they're not great, but they're better than nonfunctional, overheated FEXen.chris margethttps://www.blogger.com/profile/06646973209424821070noreply@blogger.comtag:blogger.com,1999:blog-3266263034124005485.post-5357705105298862242015-08-07T21:28:05.555+01:002015-08-07T21:28:05.555+01:00They are not that great.

This means the cables have to run through the length of the sleeve and come out the front of the rack. Now since PDU's are installed at the back, it means you have to used up 1U underneath it to pass your cables back through the rack. So they are 1U but makes you use 2U because they didn't make any holes to have your power come out. Also if you run containment you'll need to buy some sort of 1U with brush openings so that you can still block most of the air from going through the 1U that your cables need to run through.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-3266263034124005485.post-2796913154578326612012-01-30T13:08:27.660+00:002012-01-30T13:08:27.660+00:00Cool, can you share that document?
