Console port
The management module incorporates one RS-232 serial port for local management and configuration . This
port uses an RJ-45 connector mounted on the front panel . To connect to the console, an RJ-45–to–DB9 cable is
provided with each switch and is similar to the "rollover" cable used on Cisco products .
Auxiliary Port
The management module includes a USB auxiliary port used for offline data transfer of files without the need
for a network to be set up . System code can be copied to a USB memory stick, and the system can copy this
image from USB, just as you would over the network .
J9093A HP ProCurve 8200zl Fabric Modules
The switching fabric is provided by two fabric modules, each housing a single ProVision Fabric ASIC . Much like
the design of the award-winning HP ProCurve Switch 5412zl, the Fabric ASICs are load-sharing and resilient to
each other . With both fabric ASICs operational, all 12 slots of the Switch 8212zl provide wire-speed switching
capacity for up to 288 Gigabit ports, or up to 28 .8 Gbps per slot when used with 10-Gigabit ports .
In the unlikely case of a failing ASIC on either of the fabric modules, the resilient design of the Switch 8212zl
lets it continue to operate with all 12 slots interconnected by the remaining fabric module, albeit at half
capacity (14 .4 Gbps capacity per slot) until a repair cycle can be performed . Replacing a failed module is
simply a matter of removing two screws and replacing the module . Sub-second recovery of the switching fabric
is performed automatically .
J9095A HP ProCurve 8200zl System Support Module
The Switch 8200zl series is a fully repairable core switch . All active components for the system are mounted
on removable, quickly replaceable modules . Where the management and fabric components of the system
are redundant and resilient to failure conditions, other components that normally would be designed into the
backplane are instead designed into the System Support Module (SSM) . The SSM contains:
• System clock
• Multiplexer circuitry for management module to interface module communication
• Fan controller circuitry
On a Switch 5400zl series chassis, these components are designed into the chassis backplane .
