Processor
The CPU processor is a Freescale PowerPC 8540 operating at 667 MHz.
Memory
SDRAM
Synchronous Dynamic RAM is used for the storage of uncompressed executable code and data
structures. The SDRAM consists of a 256 MB DDR-1 DIMM in the base module, expandable up to 1
GB. The DDR-1 interface is 64 bits running at 166 MHz bus speed (333 MHz data rate).
Flash
The flash consists of a 128 MB Compact Flash expandable up to 1 GB, and a 4 MB mirror-bit flash.
The mirror-bit flash is used for initial boot code. The Compact Flash is used for non-volatile
configuration storage, and compresses code storage. The Compact Flash is socketed for future upgrade
capability.
The Compact Flash may be programmed in a bulk fashion or one sector at a time. Since all application
code is executed out of SDRAM, the Compact Flash may be programmed while the router is
operational. The Compact Flash is sized such that a backup copy of an older revision of application
code may also be stored.
Console port
The management module incorporates one RS-232 serial port for local management and configuration.
This port uses a DB-9 male connector mounted on the front panel. To connect to the console, a
standard null modem cable is used equivalent to that used for other HP ProCurve switches like the HP
ProCurve 5300xl series.
Auxiliary port
The management module includes a USB auxiliary port for use in future releases of the software.
Line interface modules
The following is a description of the line interface modules supported by the HP ProCurve Switch
5406zl and 5412zl.
