memory bandwidth for the graphics subsystem. Video signals are available at the ZT 5504's
J6 faceplate connector
or at the
J5 Rear Panel I/O connector
. See "
SW2-3 (VGA Routing
Control)
" in Chapter 3 for information on directing video signals to the front or rear of the board.
The "
Video
" topic in Appendix E contains a link to the datasheet for this device.
PCI Mezzanine Card (PMC) Interface
The ZT 5504 provides a location for one on-board PMC device with front panel access. The
PMC interface is on PCI Bus 0 and uses a 32-bit 3.3V PCI bus.
The "
PMC Specification
" topic in Appendix E contains a link to the sponsoring organization for
the PMC specification.
Dual Ethernet Interfaces
The ZT 5504 provides two 10/100BaseTx Ethernet channels (A and B) through the
Intel® 82550 Fast Ethernet Multifunction PCI Controller with integrated Alert On LAN (AOL).
The 82550 consists of both the Media Access Controller (MAC) and the physical layer (PHY)
interface combined into a single component solution. Two RJ-45 connectors with integrated
LEDs are available at the faceplate. Both Ethernet channels can be directed to the J3
backplane connector. See "
Geographic Addressing (E4h)
" in Appendix C for more information.
The "
Ethernet
" topic in
Appendix E contains links to the datasheets for the Ethernet devices
used on the ZT 5504.
IDE Hard Drive
The ZT 5504 includes an on-board 2.5-inch Enhanced IDE hard drive. The hard drive is on the
ZT 5504's primary IDE channel and is assigned "device 0" (master) identity.
See Chapter 6, "
IDE Controller
", for more information.
Serial I/O
The ZT 5504 provides support for two RS-232 compatible serial ports. COM1 is accessible at
the faceplate through an RJ-45 connector or through the J5 Rear Panel I/O connector. This
port is typically used for test access. COM2 is accessible only through the J5 Rear Panel I/O
connector. No strapping option or software control is required to use either port.
The front panel RJ-45 connector is configured as DTE. SRI (Serial Ring Indicator) and SCD
(Serial Carrier Detect) signals are not included in the front panel RJ-45 connector. Refer to the
"
J10 (COM1 Serial Port)
" topic in Appendix A for a connector pinout.
Note:
COM1 signals are available to the front- and rear-panel simultaneously. Utilizing the
COM1 signal at the front and rear at the same time will cause a signaling conflict.
