Re: IBM Flex System x240 Compute Node2013-04-02T15:26:18Z in response to SystemAdminHave you got a 4093 switch in the chassis? then you want to connect it into a 1GB uplink switch?
If so then you need to buy a couple of the 1GB RJ45 SPF to connect from the chassis switch to your 1GB core network.
This looks to be the correct one.

Re: IBM Flex System x240 Compute Node2013-04-03T07:45:36Z in response to SystemAdminYou will still need the RJ45 transceiver as per this redbook:

With the flexibility of the IBM Flex System EN4091 10Gb Ethernet Pass-thru Module, clients can take advantage of the technologies that they require for multiple environments:
For 1 GbE links, you can use SFP transceivers plus RJ-45 cables or LC-to-LC fiber cables, depending on the transceiver.
For 10 GbE, you can use direct-attached copper (DAC, also known as Twinax) cables, which come in lengths between 1 m and 5 m. These DAC cables are a cost-effective and low-power alternative to transceivers, and are ideal for all 10 Gb Ethernet connectivity to the Top-of-the-Rack (TOR) switches. For longer distances, you can use SFP+ transceivers (SR or LR) plus LC-to-LC fiber optic cables.
