    Have 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.

    Hi

    We have EN4091 Pass thru module.

    You will still need the RJ45 transceiver as per this redbook:

    additional excerpt

    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.
