That can fix cron but not any of the other programs like mail.

comment How do fiber Ethernet transmitters set their power output?
OK, fair enough. Do you know then why the switch reports the current transmit power output as a specific number within the SFP's range for a particular port? For example, an SFP rated for -3 to -9 dBm shows in the management console as outputting -5 dBm. Does the SFP really know how much it is sending if it can't control it?

I'm not sure how to interpret your answer. To be clear, I'm not concerned about saving power here--I'm wondering if I can somehow make the transmitter use more power in configurations that need it (e.g. if the fiber is quite long or has a few joints, but not so long that I necessarily want to switch to long-haul SFPs).

The problem I'm trying to solve is that in some configurations I get too little light on the receiving side, so I want to know if this is something that software/firmware can resolve, or if the only way to fix it is by buying more/different hardware.

It looks like the HP Z210 has good graphics card support without forcing you to buy one that comes with.

It would be easier for me to not buy Dell (since I don't have a business relationship with them at this point).
