Get an LB6, LB8 and LB9, complete the Quanta LB collection! Then you can start on the LY line...
I meant in your systems connecting to the switch... if you don't have 10Gig then the switch doesn't do you any good, right? You asked if you needed one
Lies! Anything with more blinky lights, no matter how useful it is, makes your rack better. If it has blinky lights, you need it.
Wanted to impulse purchase this at work today, but they're just too noisy for me. Anyone modded these with a quiet fan(s) and/or seen how easy this are to open up?
@tby: Thanks for your reply regarding the rack ears!
a) SFP+@ LB4M -> SFP+@ LB6M
b) 2* SFP+@ LB4M -> static or dynamic LAG -> 2* SFP+@ LB6M
But I haven't played with LAG, yet...not sure if it is worth to go through the configuration hassle!?
I'm thinking about that, too. Obvious possibilities:
a) SFP+@ LB4M -> SFP+@ LB6M
b) 2* SFP+@ LB4M -> static or dynamic LAG -> 2* SFP+@ LB6M
But I haven't played with LAG, yet...not sure if it is worth to go through the configuration hassle!?
Although, it may be the case that someone will get lucky. I remember with LB4Ms not everyone had the same firmware versions. There are definitely ways to dump the flash from these if they are anything like Quanta's other switches.
Without having any clue about "full-fledged" layer3 switches: it looks like CLI Functions of these two are identical / comparable
- LB4M with image v5.13.12.14 / VxWorks5.5.1 (aka "routing image")
- LB6M with image v1.2.0.14 / Linux 2.6.21.7
(Thats only my first impression after superficially digging through the CLI.)
But I couldn't figure out how to backup the whole flash
At least one thing is funny: looking at the LB6M images using notepad++ you'll find strings like this one:
Which makes this theory really interesting:
- LB4M with image v5.13.12.14 / VxWorks5.5.1 (aka "routing image")
- LB6M with image v1.2.0.14 / Linux 2.6.21.7
(Thats only my first impression after superficially digging through the CLI.)
Transferring both image slots from LB6M to a TFTP Server goes the same way (it goes on LB4M):
Code:
copy active tftp://<ip-of-tftp-server>/image1
copy backup tftp://<ip-of-tftp-server>/image2At least one thing is funny: looking at the LB6M images using notepad++ you'll find strings like this one:
Code:
FASTPATH System for lb4m=> Any ideas how to get the U-boot from LB6M? ...and how to push it on a LB4M?
It looks like the LB4M has the same command line interface (CLI) as the Netgear M4100 Managed Switch. I downloaded the Command Line Interface (CLI) User Manual for the Netgear M4100 switch and the commands are the same. The Netgear M7100 series switch has routing capabilities. I am wondering if the Netgear firmware can be loaded on the Quanta switches.

Bonus points if the lights dim when you turn it on.
Did you happen to take any other pictures while you had it open? Curious to see the fan locations and available real estate.When you open them up you can tell where they were able to get so many from

Each of the 2 I ordered came with 2 bonus SFP+'s as well, and they were packed ans shipped quick.
The layout is practically identical to the LB4M layout inside. There are 3 rear fans and dual hotswappable powersupplies in the rear.
Cheers! I'm interested in the switch but not interested in 60 db of noise. I've had great success with swapping out fans in the past, trying to see if I can get away with it here as well.
