Introduction
PMCA and PMCB These slots allow front panel access to PMC devices installed on the
ZT 4901. PMCA is also available through the J5 RPIO connector
(see Table 8 on page 34).
Fibre Channel A and B These SFP-MSA receptacles accept Fibre Channel transceiver
modules.
Fibre Channel Status LEDs Green: The Firmware is loaded and the Fibre Channel interface is
available.
Yellow: A link error has been detected. This can occur when a
device has locked the link, or a cable is not installed correctly.
2.2.2 Host PCI Bus
The ZT 4901 receives PCI signaling from the host processor board through a 190-pin, 64bit,
66 MHz-capable board-to-board connector (J18). The Host PCI Bus interfaces with the ZT 4901's
Local PCI Bus P2P Bridge. The host processor sets signal M66EN on the board-to-board connector
to establish whether the bus operates at 33 MHz or 6 6MHz, as defined by the PCI specification.
In addition to the Host PCI Bus, the board-to-board connector carries the I2C System Management
Bus. This allows the host processor board to monitor the health of the ZT 4901 IOX board and
access the ZT 4901 FRU information.
2.2.3 Local PCI Bus
The ZT 4901's Local PCI Bus is a 64-bit 33/66 MHz bus that connects the host processor board to
the IOX's two PMC sites, Fibre Channel processor, and Backplane PCI Bus P2P Bridge. The local
PCI bus operates at 33 MHz or 66 MHz depending on the interface speed of the host PCI bus.
2.2.4 Backplane PCI Bus
The backplane PCI bus is a 64-bit bus that allows the host processor board to provide System
Master functionality to a second CompactPCI bus segment. This functionality is accessed through
the ZT 4901 J1 and J2 CompactPCI interface. The backplane bus operates at 33 MHz in RSS Mode
and 33/66 MHz in Standard System Slot Mode, depending on the interface speed of the Host PCI
Bus.
The backplane CompactPCI interface (J1 and J2) can operate in Standard System Slot Mode, RSS
Mode, or Drone Mode (isolated from the backplane). The interface's operating mode is determined
by the CompactPCI Interface Controller. For more information, see Section 2.2.6, “CompactPCI
Interface Control” on page 13.
2.2.5 PCI-to-PCI Bridge (P2P)
The ZT 4901 features one Intel®21154 PCI-to-PCI bridge to support its J1/J2 CompactPCI
interface. The bridge provides the isolation, arbitration, and clocks for up to seven PCI peripheral
cards without the need for an external bridge board.
Special features of the 21154 include:
•64-bit PCI operation
Downloaded from Elcodis.com electronic components distributor

Intel® NetStructureTM ZT 4901 Mezzanine Expansion Card Technical Product Specification 13
Introduction
•33 MHz or 66 MHz PCI bus operation
See Appendix B, “PCI-To-PCI Bridge” for more information about the bridge chip.
2.2.6 CompactPCI Interface Control
A CompactPCI bus manager provides bus arbitration and bus mode control for the backplane
CompactPCI bus. The ZT 4901 supports several bus modes including Standard System Slot Mode,
Drone Mode, and RSS Mode.
2.2.6.1 Standard System Slot Mode
In Standard System Slot Mode, the ZT 4901 IOX board functions as a System Slot Master per the
PICMG 2.0 specification. By default, the IOX board is in Standard System Slot Mode whenever it
is not operating in Drone or RSS Mode.
2.2.6.2 Drone Mode
The ZT 4901 and its host processor board operate as the System Master from the system slot. The
boards can also operate in Drone Mode from a peripheral slot. In Drone Mode, the boards receive
power from the system but cannot communicate on the CompactPCI bus. Onboard logic uses
SYSEN# to qualify the ZT 4901's location when inserted in a peripheral slot, thereby isolating the
board from the CompactPCI bus.
The ZT 4901 and host processor board support live insertion and removal when operating in Drone
Mode (in peripheral slots, the board is operating in isolation from the backplane). When used in
this manner, the CompactPCI Hot Swap Specification, PICMG 2.1, Version 1.0 does not apply.
Caution: The ZT 4901 and its host processor board are not intended to be hot swapped in a standard system
slot. Hot swapping the processor board in the system slot may damage other boards in the system.
2.2.6.3 RSS Mode
As an extension of the ZT 4901's role as a System Master, the IOX board is capable of being a
Redundant System Master in a High-Availability RSS system. The signal RSS- is used to
determine if the board is in an RSS environment. In RSS Mode, the board's CompactPCI interface
controller is responsible for managing control of the bus and backplane clocks during a transfer of
bus ownership.
The ZT 4901 and host processor board support live insertion and removal when operating in RSS
Mode. When used in this manner, the CompactPCI Hot Swap Specification, PICMG 2.1, Version
1.0 does not apply.
Refer to the High Availability Software Development Kit for Intel®NetStructureTM CompactPCI
System Master Processor Boards software manual for more information about operating the
ZT 4901 in an RSS environment.

Introduction
2.2.7 Hot Swap Controller
The ZT 4901 draws local power through its J1 backplane connector. An on-board hot swap
controller manages the board's power up and over-current protection. The IOX board powers up at
the same time as its host processor board and uses the following power related signals for control
(on the Board-to-board connector):
•MEZ_POR-: Output to the host processor board indicating that the IOX board is fully inserted
and that backplane voltages are valid.
•SBC_HSPOR-: Input from the host processor board indicating that the host recognizes
MEZ_POR- and that the host is fully inserted and its backplane voltages are valid. This input
can be driven by the host’s Baseboard Management Controller (BMC) to power down the
Mezzanine.
•MEZ_PWROK: Output to host indicating that the IOX board’s back end power is on and
voltages are valid. This output can be connected to the host’s BMC for power-on/reset control.
2.2.8 System Management Bus
The ZT 4901 supports an I2C compatible Bus to provide health monitoring functions and access to
vendor and factory information about the board. The IOX board extends both the IPMB power
(IPMB_PWR) from J1 and the Host I2C interface to the J5 RPIO connector. On-board devices
connected to the Host I2C interface are powered from the J1 IPMB_PWR. For information about
the monitoring features of the ZT 4901, see Chapter 4, “System Monitoring and Management.”
2.2.9 Fibre Channel
Fibre Channel is a high-performance bi-directional serial data communication standard for use
between servers, mass storage subsystems, and peripherals. Fibre channel connections can be
point-to-point or routed through hubs or switches. Fibre Channel's long-distance, high-bandwidth
capability makes it ideal for storage area networks, computer clusters, and other data intensive
computing applications.
The ZT 4901 uses a QLogic* ISP2312 Fibre Channel Processor to provide two 2 Gbit channels
that are switched between the front-panel Small Form-Factor Pluggable (SFP) receptacles and the
J5 RPIO connector. The host processor board communicates to the Fibre Channel processor
through the J10 board-to-board interface. Appendix B, “Fibre Channel Processor” contains a link
to more information about the Qlogic ISP2312 Fibre Channel Processor.
An on-board option ROM contains BIOS setup information for the ZT 4901's Fibre Channel
processor. A serial EEPROM contains Fibre Channel configuration information such as the World
Wide Identification (WWID).
Note: If a ZT 4901 Fibre Channel* controller port is to be used as a boot source from the front panel SFP
receptacle, the bootable Fibre Channel device must be connected to SFP receptacle B (either A or
B can be chosen if connected via the Rear Panel I/O J5 connector).
The bootable Fibre Channel device will then be detected by the ZT 5524 BIOS, and the user must

Introduction
select the detected device from the ZT 5524 BIOS Setup Utility Boot Menu, and place it in the
desired Boot Order.
2.2.10 Port Bypass Circuit
Fibre Channel A and B each incorporate an on-board port bypass circuit (PBC). The PBC provides
continuous connectivity to the SFP receptacles at the front, and to the J5 RPIO connector.
2.2.11 Dual PMC Interfaces
The ZT 4901 provides two 64-bit 66 MHz PCI Mezzanine Card (PMC) sites, both configured for
3.3 V PCI signaling. Front-panel access is provided for both sites. One PMC site (PMCA) maps
user I/O to the ZT 4901's J5 RPIO connector, as defined in the PICMG 2.3 specification.
For information about the ZT 4901's PMC interfaces, see Appendix A, “J11 - J13 and J21 - J24
PMC Connectors”.
2.2.12 Rear-Panel I/O

3.4 Attaching the IOX Board to the Processor Board
The IOX board must be attached to a host processor board before it can be installed in a system.
The following hardware is included with the ZT 4901 to attach it to the ZT 5524 Processor Board:
•Roundhead Screws (5): Used to attach the standoffs to the ZT 4901.
•Flathead Screws (5): Used to attach the ZT 5524 to the standoffs (and thereby the ZT 4901).
•Standoffs (5): Used to secure the boards together and maintain 0.8 in board spacing.
•Ejector Ganging Pins (2): Used to tie together the operation of the boards' ejectors.

Getting Started
Warning: Static electricity can damage electronic components. Wear a wrist strap grounded through one of
the system's ESD ground jacks when servicing system components.
Note: To ensure secure long-term operation, it is recommended that a threadlocking compound be
applied to the screws used in attaching the IOX board to the processor board. Factory installed
screws are coated with a threadlocker where appropriate.
1. If you wish to install PMC devices on the IOX board, this must be done prior to attaching the
IOX to the host processor board (but after Step 6 below). For information about installing
PMCs, refer to Chapter 5, “Installing Accessories.”
2. Take the necessary precautions to protect the ZT 4901, ZT 5524, and any other devices you are
working with (such as PMCs) from static discharge.
3. Remove the protective cover from the solder side of the host processor board. Lay the
processor board, solder-side down, on a flat surface.
4. Insert one ganging pin into the appropriate hole in each of the processor board's ejectors and
press the pins in until they seat. Approximately half of each pin should still be exposed.
5. If the standoffs are not attached to the board, remove any screws that may be in the standoffs.
If the standoffs are attached to your IOX board, remove any screws that may be in the
processor-board-side of the standoffs and skip Step-6.
6. Attach the five standoffs to the appropriate holes on the IOX board using the five panhead
screws. Screws should be tightened to 2 to 4 inch-pounds. This step must be done prior to
attaching accessory devices (such as PMCs) to the board.
7. Lay the IOX board on top of the processor board so that the board-to-board connector and the
ejector ganging pins are in alignment.
8. Press the boards together until the board-to-board connector completely engages. The boards
should fit together smoothly, do not force them. After the board-to-board connector is properly
seated, check that the standoffs are flush with the appropriate holes on the processor board and
that the ejector handles are flush with one another.
9. Fasten the processor board to the standoffs using the five countersunk screws (mounting
holes on the processor board are countersunk). To ensure proper alignment and avoid warping
either board, thread and seat all of the screws before final tightening. Screws should be
tightened to 2 to 4 inch-pounds.
10. Reattach the solder-side cover to the processor board.
3.5 Removing the IOX Board from the Processor Board
The following instructions cover the mechanical aspects of removing a ZT 4901 IOX Board from a
ZT 5524 Processor Board. Refer to Figure 4, “Mounting the IOX Board” on page 18 for an
exploded view of the parts involved in this operation.
The IOX board must be removed from the host processor board to add or change an accessory
(such as a PMC device). For information about installing PMCs, refer to Chapter 5, “Installing
Accessories.”

1. Take the necessary precautions to protect the ZT 4901, ZT 5524, and any other devices you are
working with (such as PMCs) from static discharge.
2. Remove the protective cover from the solder side of the host processor board.
3. Remove the five flathead screws that attach the processor board to the complex.
4. Pull the IOX board evenly away from the processor board.
At this point, you may either prepare the host processor board for use without the IOX board or you
can install the desired devices on the IOX board and reattach it to the processor board.
3.6 Installing the IOX/Processor Board Complex
The IOX/Processor board complex is capable of operating in a variety of environments.
Section 2.2.6, “CompactPCI Interface Control” on page 13 defines the IOX board's various
operating modes. Refer to platform-specific documentation for instructions on installing this board
complex into a system slot, peripheral slot, or in an RSS system.
When working with the IOX/processor board complex, remember that the boards are physically
attached to one another and must be installed and removed together. The boards' ejector handles are
ganged together and you must depress the release tabs on the processor board's handles to unlatch
the ejectors. Refer to Figure 5 on page 20 for basic ejector handle operation instructions.
