Celera NX4 - 4 x 1gige upgrade to 2x10gige

I have a celera nx4 with 2 blades, that are of the type 4 port 1gig.  I wondering what my options are for "Upgrading" them to connect to a Nexus 5548 switch.  I'd like to go full 10gige if possible.

can you just swap the Network Modules out? or do you have to swap the blades out?

Here are the part numbers for the Network Modules.

019-078-032 SFP transceiver multimode for 1-, 2-, or 4-GbE ports. This SFP is used with these

ports: BE 0, BE 1, AUX 0, AUX 1.

 

019-078-041 SFP+ transceiver limiting multimode for 10-GbE ports. This SFP is used with these

ports: fxg0, fxg1

Here are the part numbers for the blades

100-562-150 Blade with dual-inline memory modules (DIMMs) and transceivers, four copper ports, 4-GB

memory

 

100-520-066 Blade with DIMMs and transceivers, two 10-GbE optical and two copper ports

I probably wont be able to do it if i have to swap the blades, i'm assuming those are pretty expensive.

I'd like to breath some new life into this box it's only 3 years old.  it's going to cost me 2.5k to get the 1gig uplink modules for the 5548.  just figured if i'm spending 2.5k how much more to just go 10gig.

maybe those blades aren't to expensive if they were around 2k ea i could probably get budget aproval.  but i can't find any pricing anywhere on the web.

I dont want to void my service contracts, etc.  but i dont realy do business with the company i purchased it from anymore (CDWG)  I'm working with AOS but it's going to be several days before someone can look into it.

So i'm just wondering if anyone here might know:

A) are these types of "Upgrades" supported

B) do you know if it's just the Tranciever Module, or the BLADE

C) ball park on costs...
