[AusNOG] Console Server with Digital I/O

2017-10-03 Thread Shane Chrisp
Hi All,  I am reaching out the list to see if anyone on list has come across a Console server with ~8-16 serial ports along with similar number of Digital I/O's? I would rather not have to reinvent the wheel if I can avoid it. -- Regards Shane Chrisp 2000 Computers & Networks Pty Ltd U8,

Sure, but when one observes the default vendor position is front to back airflow, if one then applies logic, you can conclude back to front is deployed as a cost cutting measure sans structured cabling. Kind regards Paul Wilkins On 4 October 2017 at 16:10, Jay Dixon wrote:

Sam, In an SP environment, you may well have whole rows dedicated to a single service - email, or web say. In the rack itself, you'll have web_node_5007, web_node_5008 etc. In the enterprise, you'll have a few email blades, internal web, external web, next to a bunch of file and print etc etc

that would mean the concept of patch by exception does not require patch panels and clearly even with that methodology it's used. Seems like some crack smoking logic there. I bet 90% of most peoples access layer has the same configuration on their switches. I don't think scale has anything todo

Because SPs have the luxury to not use structured cabling, due to scale where all switch ports share a common configuration, so there's no need for a patch panel, just patch direct to the switch, whereas in enterprise, inadvertent swapping of ports leads to P1s, hence, structured cabling is fairly

There's enterprise racks, and SP racks and I'd say to generalise, Enterprise do the ports to the front to structured cabling, while SPs will reverse mount for shorter wire runs and density. Also swapping out reverse mounted switches is a huge pain. Kind regards Paul Wilkins On 4 October 2017 at
