SX350 recovery delay when unit fails

impi
Level 1
Level 1

Hi all,

 

we are configuring our first SX350 Cluster and then we are testing some simple things.

 

First of all here is our setup :

   - 4 SX350X 52

   - Unit 1 is linked to unit 2 using 2 copper cables

   - Unit 2 is linked to unit 3 using 2 fibbers

   - Unit 3 is linked to unit 4 using 2 copper cables

   - Unit 4 to unit 1 with fibbers

 

Unit 1 is master

Unit 2 is standby

Unit 3 & 4 are member

 

Nothing else than cluster is configured, really simple setup

 

We plugged one computer on each switch and then pinged from every computer to other one

We also pinged the management IP from another machine

 

If we remove power from unit 1 the we loose all ping (even ping from computer 3 to computer 4 for example), this is quite crazy. Port seems to be down.

It lasts about 1.5 minutes.

 

Did we misundertood something about cluster ?

 

Thanks a lot

 

Cédric
