This CompactPCI® Single Board Computer is designed for telecommunications and Internet applications requiring completely integrated multiprocessing solutions for increased performance and system reliability. Optionally, it can operate in a peripheral slot in drone mode, whereby it does not communicate on the CompactPCI bus. This option permits use of the ZT 5503 as a stand-alone computer in a peripheral slot.
The high performance of the ZT 5503 comes from the Intel® Pentium® III
processor and the CompactPCI bus. Support for major operating systems and
real-time software speeds application development. A generous set of onboard
embedded features and the 6U Eurocard mechanical form factor address the system
integration and reliability requirements of OEM system builders.
The 850MHz Intel® Pentium® III processor - low power provides excellent computing power for the embedded system designer, incorporating a 100MHz processor side bus and 256KB of L2 cache. The ZT 5503 may be configured with a companion rear panel transition board (ZT 4804 or ZT 4806) specifically designed to support the available I/O signals.
The ZT 5503 functions as a 6U system processor in a CompactPCI multiprocessing system (Compactnet®). The ZT 5503 interfaces to the CompactPCI backplane through a transparent, PCI-to-PCI (P2P) bridge, allowing it to communicate directly with all peripheral CPU boards in the system via the CompactPCI bus.
The ZT 5503 is designed to optionally operate in a peripheral slot. In this mode, it receives power but does not communicate on the CompactPCI bus. Onboard logic qualifies its location when inserted into a peripheral slot, thereby isolating the board from the CompactPCI bus.
All RAM options for the ZT 5503 are Error-Correcting Code (ECC) SDRAM for improved reliability and data integrity, and the board supports memory options of 1GB. The Intel® Pentium® III processor contains integrated L1 and L2 cache memory.
The ZT 5503 includes 4MB of onboard flash memory. The flash memory supports the system BIOS, which is field-upgradeable, and the additional flash memory may store a bootable operating system image. Additional flash memory capacity may be added with a CompactFlash carrier mezzanine card, provided as an accessory and available in lieu of a hard drive. This rugged, solid-state storage solution provides complete software compatibility with operating systems and applications, which support standard IDE devices.
Two Ethernet ports deliver high networking performance via onboard 10/100 Mbps Ethernet LAN interfaces. Either 10 or 100Mb Ethernet protocols are available through auto-configuring RJ-45 front-panel connectors. Link and activity status LEDs provide Ethernet operation, and two additional Ethernet ports are located on the rear panel.
An EIDE hard drive is mounted on the ZT 5503 in the standard product configuration. Space remains on the baseboard, and connectors are provided for a single PMC card.
An onboard, two-stage watchdog timer is provided for system integrity. Once enabled, failure to strobe the watchdog timer within a programmable time period (1s, 8s, 64s, 256s) generates a non-maskable interrupt (NMI or processor "INIT"), followed by a hardware reset.
An onboard SVGA-compatible graphics controller, CHPS 69000, is included with
video connectors provided on the front plate.
The ZT 5503 comes standard with an embedded BIOS loaded in onboard flash. The BIOS is user-configurable to boot an operating system residing in local flash memory, from a fixed or floppy drive, or over a network. The ZT 5503 is PC-compatible and will run operating systems developed for the PC. Enhanced support is also provided for Windows 2000, Linux and VxWorks, including additional drivers for select peripherals and flash drives.

Note: To provide proper cooling to the ZT 5503, each unused
slot in the chassis should be populated with an air management blade. All
rear slots should be populated with a rear filler panel. See the list below
