Nexus 5000 SFP Question

[Warren Julius]

Are the DS-SFP-FC8G-SW fiber module for exclusive use in the Nexus 5000 expansion module. Or will this work in the Nexus 5548UP Fiber Ports?

FC optics work into a Nexus 55xxUP switch. You juste have to force the type of the ports :

slot 1
  port 1-30 type ethernet
  port 31-32 type fc

It will require a reload of the slot or the switch if you force the type of the baseslot of the switch.

Then optics will be recognized. Example with a SFP-FC-4G :

N5K-01# show interface fc 1/31 transceiver
fc1/31 sfp is present
    Name is CISCO-FINISAR
    Manufacturer's part number is FTLF8524P2BNL-C2
    Revision is D
    Serial number is FNS153806BU
    FC Transmitter type is short wave laser w/o OFC (SN)
    FC Transmitter supports intermediate distance link length
    Transmission medium is multimode laser with 62.5 um aperture (M6)
    Supported speeds are - Min speed: 1000 Mb/s, Max speed: 4000 Mb/s
    Nominal bit rate is 4300 Mb/s
    Link length supported for 50/125mm fiber is 150 m
    Link length supported for 62.5/125mm fiber is 70 m
    Cisco extended id is unknown (0x0)
    No tx fault, no rx loss, in sync state, diagnostic monitoring type is 0x68
    SFP Diagnostics Information:
        Temperature           :  28.08 C

I have an issue on the other topic in this section, if you can help it will be appreciated

The 5548UP as I understand, comes standard with Unified Ports. This is why the DS-SFP-FC8G-SW can be used, which would in other circumstances need an Expansion Module.
