We just implimented a pair of EX2300 as TOR Switches. Last week I had one hard-lock and crash, console was inoperable. It came up after a power cycle.
Called up JTAC, both had SNMP Traps for fans that didn't exist being sent to syslog so they replaced both of them; the switch that crashed did not turn off when sent a request system power-off so that looks to be a hardware fault.
I change them both out out Saturday, find out one of the replacements rebooted into the loader screen and won't take firmware; it's giving me filesystem alignment errors so I'm guessing storage on the switch itself is toast. This is after it took firmware, loaded up fine, took a config, and was working.
We're up right now and I'm getting in early today to get back on the line with JTAC to continue troubleshooting and to make sure they have someone onsite in case another switch fails.
Am I just really unlucky or are they going through some hardware\supply problems right now? Juniper gear has always been rock solid for me once you get it in and all the bugs worked out.
Thank you.
