It depends on type of power module (AC or DC) and *which* modules you remove. An M320 can operate with two out of four DC power supplies (we have verified this): http://www.juniper.net/techpubs/hardware/m320/fru-m320-dc-power-supply.pdf and from what I can see, it can also operate with two out of four AC power supplies: http://www.juniper.net/techpubs/hardware/m320/m320-ac-power-supply-fru/m320-ac-power-supply-fru.pdf Steinar Haug, Nethelp consulting, [EMAIL PROTECTED] _______________________________________________ juniper-nsp mailing list [email protected] https://puck.nether.net/mailman/listinfo/juniper-nsp
