Figure 6. Back panel of the 3534 Model F08

Hardware components

The 3534 Model F08 system board is a single-board design with a highly integrated
CPU. The Intel
this platform. It provides over 70% of the functionality for the digital section of the
system board. The system uses three types of memory devices: dynamic random
access memory (DRAM), Flash File, and Boot Flash. On the Fibre Channel section
of the system board, the following three components provide high-speed data
transfer:
v The Bloom ASICs
v The Serializer/Deserializer (SERDES)
v The SFP media. SFP media interfaces support SWL and LWL.

CPU subsystem

An Intel 80960VH CPU is used for management functions and switch initialization.
The CPU runs the Fabric OS and is responsible for switch initialization,
configuration, and management. Switching functionality is provided by the ASIC.
The following peripherals are also supported:
v An Ethernet port
v A serial port
v Three digital thermometers
v A real-time clock
v General input/output (I/O)
The CPU subsystem is a mixed voltage system that uses 1.8 V, 2.5 V, 3.3 V, and 5
V, depending on the device. The maximum board power consumption is 50 W.
Features
The 3534 Model F08 CPU subsystem includes the following features:
v A 80960VH-100 MHz CPU
v An SDRAM controller with parity check at 33 MHz
v A peripheral control interconnect (PCI) bus arbiter
v Main memory (SDRAM): 32 MB
v Flash memory: Dual 8 MB
v Boot flash memory: 512 bytes of 8-bit for system start
v 10BASE-T or 100BASE-T port for management connection with RJ45 connector
v One RS232 port with DB9 connector
