Hi Bill, It all depends on what other modules you have installed in your chassis. I am running a 6509-E with 3000W power supplies using 110v, however I have to run them in combined mode. To give you some real-time data here's the output from my 'sh power':
system power redundancy mode = combined system power total = 1952.16 Watts (46.48 Amps @ 42V) system power used = 1275.54 Watts (30.37 Amps @ 42V) system power available = 676.62 Watts (16.11 Amps @ 42V) Power-Capacity PS-Fan Output Oper PS Type Watts A @42V Status Status State ---- ------------------ ------- ------ ------ ------ ----- 1 WS-CAC-3000W 1171.38 27.89 OK OK on 2 WS-CAC-3000W 1171.38 27.89 OK OK on Pwr-Allocated Oper Fan Type Watts A @42V State ---- ------------------ ------- ------ ----- 1 WS-C6509-E-FAN 150.36 3.58 OK Pwr-Requested Pwr-Allocated Admin Oper Slot Card-Type Watts A @42V Watts A @42V State State ---- ------------------ ------- ------ ------- ------ ----- ----- 1 WS-X6516A-GBIC 152.04 3.62 152.04 3.62 on on 2 WS-X6148-RJ-45 100.38 2.39 100.38 2.39 on on 3 WS-X6148-RJ-45 100.38 2.39 100.38 2.39 on on 4 WS-X6148-45AF 107.94 2.57 107.94 2.57 on on 5 WS-SUP720-BASE 315.00 7.50 315.00 7.50 on on 6 (Redundant Sup) - - 315.00 7.50 - - Inline Inline Inline Inline Pwr-Requested Pwr-Allocated Local-Pwr-Pool Power Slot Card-Type Watts A @42V Watts A @42V Watts A @42V Status ---- ------------------ ------- ------ ------- ------ ------- ------ ---------- 4 WS-F6K-FE48-AF - - - - 34.61 0.82 On Have a good day, Aaron ------------- Aaron Childs Assistant Director, Networking Westfield State College http://www.wsc.ma.edu/it/ -----Original Message----- From: cisco-nsp-boun...@puck.nether.net [mailto:cisco-nsp-boun...@puck.nether.net] On Behalf Of Bill Blackford Sent: Tuesday, May 26, 2009 1:52 PM To: cisco-nsp@puck.nether.net Subject: [c-nsp] Cat 6509 Power supplies I have a question about power supplies. I am upgrading a 6509 chassis from SuP1/MFSC2 to a pair of SUP720-3BXL's, fan and new power supplies. I originally spec'd a pair of 4000W units. Now as we know, these can only support NEMA L6-30, vs. the variable power supplies such as the 3000W. I've run out of L6-30R's in my data center as our new rack PDU's are of this spec. I may need to use 110V NEMA 5-20 plugs. Can the 3000W power supply (in redundant mode) support a fully populated 6509 chassis (no POE) when using 110VAC?
