Yes.... that's why in our latest EX4200 VC we are creating two "rings" of switches. Since it's mainly servers where we can run teamed NIC's (one to each "ring" switch) we are hoping that during any upgrades/outages things will continue to operate. It's not fully implemented yet but that's our plan... 7 EX4200 on one ring and 7 EX4200 on another to start...

Just an FYI, because I've seen this bite people before (not specific to your question)... software upgrades on EX4200 VCs are NOT hitless - the whole VC is down for the duration of the upgrade (sometimes 15+ mins). VC != redundancy/HA, VC = less switches to manage.
