each module is shipped separately from the chassis. the different types of supported modules are described in the following sections. as of this printing, the following modules are supported in procurve 8100fl switches:

    1 procurve 8108fl redundant switch fabric module (j8729a)

    2 procurve 8116fl redundant switch fabric module (j8730a)

    3 procurve switch fl redundant management module (j8731a)

    4 procurve switch fl 1-port 10-gbe lr interface module (j8733a)

    5 procurve switch fl 10-port 100/1000-t interface module(j8734a)

    6 procurve switch fl 10-port mini-gbic interface module(j8735a)

    7 procurve switch fl 1-port x2 10gbe interface module (j8736a)

    the switch 8116fl has two unused slots labelled em above each management module slot. these two slots are reserved for future use.

    to avoid damaging modules and the backplane, be sure that you insert each type of module into its appropriate slot.

    switch fabric module

    each procurve switch 8100fl requires one switch fabric module to process traffic for any interface module. a second switch fabric module can be installed for redundancy.

    switch fabric modules (half-height module for switch 8108fl; full-height module for switch 8116fl) are installed in slots labelled fm. when installing two modules, install the primary module in slot fm-a; install the secondary module in slot fm-b. (when installing a single switch fabric module, you can install the module in either slot.)

    the 8108fl switch fabric module and 8116fl switch fabric module are not interchangeable. you can install the half-height module only in the 8108fl switch—the 8116fl switch requires a full-height switch fabric module.

    management module

    a procurve switch 8100fl requires at least one primary management module to operate. you can install a second management module for redundancy.

    management modules (thicker, half-height modules) are installed in slots labelled mm. you must install the primary management module in slot mm-a; you can install a second redundant management module in slot mm-b.

    the management module maintains persistent images of all software that runs on the system. the primary non-volatile storage medium is a compact flash card located on the module. this is a separate memory module for storing run-time images and tables. a front-accessible pc flash card provides another method of loading system images (reserved for future software releases).

    the management module is the main processing unit of the procurve switch 8100fl chassis. it contains system-wide bridging and routing tables, and runs the main control protocols. traffic that does not yet have an entry in the l2 lookup tables on individual interface modules is sent to the management module to be learned. after processing traffic, the management module updates the l2 tables on the interface modules that received the traffic thus ensuring system-wide coordination and visibility. in this way, the interface modules learn how to forward traffic.

    interface modules and accessories

    interface modules (narrow, half-height modules) provide network connectivity options in addition to bridging and routing functionality. the switch 8108fl has 8 slots (numbered 1-8) for interface modules; the switch 8116fl has 16 slots (numbered 1-16) for interface modules. the following interface modules are supported in procurve 8100fl switches:

    1 procurve switch fl 1-port 10-gbe lr interface module (j8733a)*

    2 procurve switch fl 10-port 100/1000-t interface module(j8734a)

    3 procurve switch fl 10-port mini-gbic interface module (j8735a) that uses and supports the following mini-gbics:

    (1)procurve gigabit-sx lc mini-gbic(j4858b)

    (2)procurve gigabit-lx lc mini-gbic(j4859b)

    (3)procurve gigabit-lh lc mini-gbic(j4860b)

    (4)procurve gigabit 1000base-t mini-gbic(j8177b)

    4 procurve switch fl 1-port x2 10gbe module (j8736a) that uses and supports the following transceivers (as of this printing):

    (1)10 gigabit-x2-sc sr optic transceiver (j8436a)

    (2)10 gigabit-x2-sc lr optic transceiver(j8437a)

    (3)10 gigabit-x2-sc er optic transceiver(j8438a)

    (4)10 gigabit-x2-cx4 copper transceiver(j8440a)

    10 gigabit-x2-cx4 optical media converter(j8439a)

    * end-of-life in summer 2006. the 1-port x2 10gbe module(j8736a), provides functionally-equivalent lr connectivity (with separate purchase of lr transceivers) in an x2, media-flexible package.
