These switches may also be used in the campus core/distribution layer, which requires a higher performance 40GbE connection with 10GbE links. I have also seen the server/equipment switches mounted reverse with distribution mounted standard.The HPE 5900 Series Switches are a range of top-of-rack (ToR) switches with high density and ultra-low latency, ideal for deployment at the server access layer of large enterprise data centers. This is fully supported by the manufacturers who generally place mounting holes for ears both front and back. In server closets, individual or small cluster of racks, as has already been mentioned, people will sometimes choose to mount the equipment reversed. Again, easier to change as needed by having everything front facing. The same holds true for large data centers, where primary switches will be centralized with distribution out to individual servers or network equipment housed in racks throughout facility. By having both the switch ports and the patch panel ports facing front, making changes as people move is easier than reaching into the back of the rack. Very often all wall ports in a building are not live, but will be connected based on need. The reason is most environments (think business office rather than server closet) use switch ports primarily connected to patch pannels. This is an old post, but the "why" never was answered.
I am not endorsing belkin products, but these are good examples of some of the different styles available. Using 10ft cables for every port that is 12 inches away to 9 ft away just turns into lots of extra cable hanging and filling up wire management space. Took hours to install new cable and patch panel organization after years of neglect after each technician, but it was much easier to manage after that point.Īlso, if you got a few bucks, buy lots of various lengths of cables to keep your cable management sanity.
I remember I got to clean up a mess like that once at an old job. A great example of this gone bad is the server fault error page. They stick the switch daisy chain connections (at least older ones always seem to do) and power/redundant power on the back as those do not get accessed often.Įasiest way to manage is to get the rack wire management plates and stick them between every switch or every other switch to help keep cables in order. They also stick the serial management port in the front also for easy access. When plugging in ports, it is useful to see the status LED as you plug it in to confirm connection. You would normally have your switches matched up with patch panels, so wherever your patch panels are, your switches will be near.
