Let’s say a cables does need to be replaced, though

The second myth (that cables in zip-tied bundles are more difficult to replace) is also somewhat flawed when it comes to SoftLayer’s use case. Every rack is pre-wired to deliver five Ethernet cables — two public, two private and one out-of-band management — to each “rack U,” which provides enough connections to support a full rack of 1U servers. If larger servers are installed in a rack, we won’t need all of the network cables wired to the rack, but EXTERNAL MINISAS  cables 5M if those servers are ever replaced with smaller servers, we don’t have to re-run network cabling. Network cables aren’t exposed to the tension, pressure or environmental changes of being moved around (even when servers are moved), so external forces don’t cause much wear. The most common physical “failures” of network cables are typically associated with RJ45 jack crimp issues, and those RJ45 ends are easily replaced.

:The answer in practice is “less than one minute” … The “trick” in that trick question is that the zip ties around the cable bundles progettazione are irrelevant when it comes to physically replacing a network connection. Data center technicians use temporary cables to make a direct server-to-switch connection, and they schedule an appropriate time to perform a permanent replacement (which actually involves removing and replacing zip ties). In the video above, we show a temporary cable being installed in about 45 seconds, and we also demonstrate the process of creating, installing and bundling a permanent network cable replacement. Even with all of those villainous zip ties, everything is done in less than 18 minutes.
