The Quanta LB6M Deal Thread

Is is possible to elaborate on the "semi happy" aspect of the Mikrotik CRS317, some of the downsides. I've been looking at it for some time now but have been concerned about its performance given all the knocks on its L3 performance. I'd really like to avoid the lb6m for home use given the noise.

 

True. I have seen some easy replacements of CRS317 fans though. + a fan replace on the LB6M is both case and PS fans if you're really looking to make a difference. I think i'm not brave enough to replace the PS fans

 

I have two that I got awhile back. Great for setting up cheap 10g for web hosting. At this price, you could setup a 10g network just for network booting.

 

Why not using a fanless switch. They are absolutely quiet.

 

Because I dont think i've ever seen a fanless 10GB Switch.

 

The power consumption on LB6M speak a different story though, for home lab, it is definitely way too much. Replacing fans isn't quickly done either, the power supply fans requires some additional work to replace. The chassis fans are ok though.

 

how bad is the power consumption? can this run with 1 PSU without it beeping and throwing error signs?

 

The image shows two power supplies:

Top = Quanta LB6M ( Delta Power Supply )

• Input 100-240V ~, 47-63Hz, 5.0A
• Output +12V - 25.0A
• Max Continuous DC Output Power 300W
• Dual fans for airflow

Btm = Arista 7050T-52 ( Emerson Power Supply )

• Input 100-240V ~, 50-60Hz, 5.29-2.2A
• Output 460W +12V - 36.0A Max / 460w +12Vsb - 2.3A Max
• Max Continuous Output Power 460W (100-240V~)
• Single fan for airflow

Both switches come with 2x Power Supplies

 

Running with just one psu is fine, no warnings but it doesn’t reduce power consumption a lot. Maybe a few watts.
Mine’s been up for over a year on one psu.

 

FYI guys... at least until end of 2017, there is another code available that provides free shipping "FREESHIP2017". This might make a slightly better deal than $25 off if shipping > $25. (it does for me in southern CA)

 

Hi Guys,

Here's the official link for $50 as Patrick mentioned.
UNIXPlus

Keep in mind the $50 is good till end of 2017. After that you'll have to use STH25OFFLB6M to get $25 off.

 

@Jack@UNIXPlus Would it be possible for you to ship to EU ?

 

Yes, we ship worldwide. Just PM me or email me at websitesales@unixplus.com

 

Earlier forum posts suggest these pull around 130 watts when run on 120V (a bit less on 230V) depending on load.

For comparison, the CRS317 is about 30 watts - 44 peak, plus SFPs - and if operating correctly shouldn't ever really spin the fans up.
It's completely worthless at layer-3, though. Sufficient processing power to handle your internet connection, but the CPU only has a 1Gbps pipe to the switch chip. The chip does support hardware-accelerated L3 forwarding/routing, and MT are working on implementation, but it'll probably be the better part of a year.

IMO, these are well worth it for the wirespeed L3 (when flashed) functionality, and what's 100W between friends?

 

Not much brother!

I look at it as 100W could be 0.9A x 110V = 100W, so since we are all paying for Amperage, not Voltage, (well, were paying for both really) shouldn't be too much on your bill.

Eh, I only run mines with one psu at a time anyway.

 

@Jack@UNIXPlus Is free shipping available as well when you use the STH members coupon?

 

You can only use one promo code at a time. Originally the free shipping was a better deal than the original $25 off STH promo so thats why we increased the STH promo to $50 instead of $25.
