    Can I attach these square-mount rails on my round-mount rack? (re: Norco RL-26 rails)

The rack I've been using has round holes and I use network rack clip nuts to attach all of my equipment but these rails seem impossible: Does anybody have any ideas or are these rails unusuable?

    Are there any SFP+ adapters to connect 2.5 GBe RJ45?

    I'm having some latency issues with my new UniFi U6-LR so I'm hoping to try a Ruckus access point. I'd love for the latest R730 (802.11ax) but realistically I'm hoping to find a used/refurbished R710/R720.

    Supermicro X9DRi-F - IPMI is partially broken after firmware upgrade

    I upgraded the IPMI firmware on my X9DRi-F to v3.62 (latest?) hoping that it added HTML5 support but it doesn't. However, I'm now having a problem with the IPMI console redirection. The IPMI webpage opens fine and I can see the firmware revision (03.62) and the server health, etc. Shutdown...

    Do 1U servers require low profile memory? (re: Supermicro CSE-512L-200B)

    Does anybody know if most 1U server cases require low profile memory? For example, I’ve purchased a Supermicro X11SSZ-TLN4F motherboard (DDR4) and a Supermicro CSE-512L-200B case (1U). It looks like low profile or “very low profile” (“VLP”) is very difficult to find. Is it common to require...
