all things cbl

At work we have a Cisco 6513 switch. It’s pretty huge. Has 13 bays for cards to go in and do their thing.

Unfortunately, I only have 120V power feeding the beast. I have two 2500W power supplies, but
thanks to the gay 120V power, I can only use 1200W of that. Sucks, I know.

So, here comes Cassidy with a new card he wants to pop into slot 12. It’s a 16 port GBIC blade,
basically to replace the 8-port one on slot 13 (see below) with added fancy stuff. Unfortunately,
it doesn’t look like I’ll have enough power for it.

To top it all off, I ordered a 16-port copper Gigabit blade as well today for this chassis. There’s
no way it’ll get power either. So something has to be done.

Option #1: Convert to 208V power.
Option #2: Get DC power supplies and supply the 6513 with power via DC.
Option #3: Cry and try to keep the tears away from the power.
Option #4: Pop in all the blades I want so it uses both power supplies (not redundant),
but if one of the power supplies dies, there wont be enough power for everybody.

Here’s the output of the “show power” command for all to see:

coreswitch>sho power
system power redundancy mode = redundant
system power total =     1153.32 Watts (27.46 Amps @ 42V)
system power used =      1099.98 Watts (26.19 Amps @ 42V)
system power available =   53.34 Watts ( 1.27 Amps @ 42V)
