you can! logical chassis do nothing for you. "Network OS 7.1 supports logical chassis cluster (LC) mode only" in own cases have a lot of customers with only one switch per rack, of course with last firmware release.

reset factory can`t help you if firmware upgrade process isn`t ended. only netinstall will format CF-card and copy new filesystem of provided version. "show firmwaredownloadstatus" confirm that previous update finished? "show version" in case of Logical chassis will show 2 partitions. in case...

There is no problem to use Logic Chassis as "normal" switch: you don`t pay for it by performance. especially when this is the Only one variant (since 7 release if I remember). of course you can try to use netinstall flash to make clean install any version of NOS (don`t forget to save license keys)

there was no demands in request - I supposed you connect devices within 5m. this is DAC, not cable. MPO(MPI) cable + transceiver costs a lot. if you really need distance more them 50m.

mc2207128-003 (3m cause 1m,2m is rare) $10-30 on ebay

for 56Gb speed you need: -original QSFP+ Mellanox equipment (cards, switche, cables. only Mellanox offered FDR14 encoding) -change speed on port from 40Gb to 56Gb (for safety, switch won`t do it itself)

I had installed about hundred of these switches without problem. Maybe you too hurry: switch has some notes: 1.it`s slow (especially in compare with sn2700). to up IB connection need 3 minutes, for ethernet less (if I remember). 2.there is no light if connection is not up. 3.if you use...

then our questions is not major. looking for manual to setup routing between networks with "route" command in windows. or make a Bridge in "network settings" with your "network-internet" card and Mellanox-card (or Solidfire: depends which one in network) of course we not mentioned if "shared...

Model is written on card. IF ONLY this is VPI model (MCX354) in "System Devices" there is "......Mellanox...mt4099......" when you can change settings: auto (default IB, Ethernet, IB). but maybe this is only ethenet MCX314 model. is 7122f SFP+ model? then how did you connect it to QSFP port...

Yes, you need install a license to get variant not only "ib-single" mode, but also "vpi-single-switch" or "ethernet" in System Profile view. VPI is when you select IB or Eth type for Each port.

you can make printscrn or copy text output of "showlicense" if you want. this will need IF only you want to replace CF-card (if it dead). GUI BNA 12.2 trial can be downloaded from ICX Ruckus site. Won`t help with cookbook. maybe exists good youtube plays, or even Brocade classes records.

no problem at all to find it. ftp://188.64.160.99/pub/fw/ and COM1 console port (or ssh if you know ip of management). forget about ezswitch

anywhere, even on public FTP "swbd76"

understood. never had such issue with 7.2 and 7.4. probably less then full NOS upgrade cause it just write small peace of code to "asic". and full switch reload.

what do you mean under "microcode update"? maybe psu and bootrom updated during normal update procedure. up to 30 minutes with reload (that takes 12 minutes)

HP A5820 very quiet switch (generation of year icx6610 I suppose) and of course better then deadly Mikrotik switches (not routers). smth around 48db, while icx64 and arista 71x have around 65db.

Then you can check another replaceable module - memory! Not often but also could be. But then probably problem with motherboard itself.

If boss have an active contract on any Brocade switch, support will send you reply password. You can write on Extreme Networks forum (cause VDX is also Brocade and uses the same) or pm

But problems in users also! 200 servers of HP and Dell (from lga2011 to lga3647) - nobody want to update servers at least once a 6 months. This NAND-chip is the same as in phones: many writes and chip is dead. At least only HP Blade has this chip on separate board and need only change it.

R420 doesn`t have SD-slot (for recovery procedure, only full versions R630/R730 have), so maybe only this way available: fohdeesha aswered on forum and there are several posts on Reddit. Step 0: connect to JTAG and check that booting process hang trying to mount some partition Step 1: determine...
