Hello,
we have a stack of 6 "SG500-52P" switches.
Connected via SFP-H10GB-Cu1M cable.
Interface Speed is 5Gb/s.
FW is 1.4.9.4
Boot Version is 1.4.0.02
Stackmode is Native Stacking.
Ring Topology, Layer 2 Mode and 4 Queues.
EEE is off.
For the past weeks we keep getting network failures.
Last night we filmed the whole stack with a camera and we documented that the LED for the Master Switch on Switch1 went off and on, for about a second.
Thats when a network failure actually happened.
Incidentally we saw that the LEDs of the Stackportcable between switch 4 and 5 is solid green, all the other LEDs of the Stackportcables are blinking.
We already swapped the Stackportcable between switch 4 and 5 with a factory new one but it didnt solve the problem, while it's still solid green.
Stack Topology:
S1 -> S2
S2 -> S3
S3 -> S4
S4 -> S5
S5 -> S6
S6 -> S1
Any suggestions?
