Getting Started—MPCMM0002 CMM
3.0 Getting Started
3.1 Installing the CMM
The Intel NetStructure
®
MPCMM0002 CMM is designed to fit in a variety of compatible
chassis and orientations. This chapter provides some useful information for installing
the management module in a chassis (shelf), but you will also need to read the third-
party documentation provided by the chassis manufacturer or system vendor for your
chassis before you install the module.
In addition to the information provided in the third-party documentation just
mentioned, you should also read and follow the precautions below:
Caution: As noted in the PICMG* 3.0 specification, AdvancedTCA* products (including the
MPCMM0002 CMM) are designed to be installed and serviced by trained service
personnel only, not equipment operators. The primary reason for this is the high
voltage level (over 60 VDC) that can be present in AdvancedTCA systems.
Caution: Many components in the system contain sensitive electronic components. Service
personnel should follow proper grounding procedures when installing or servicing this
equipment.

3.1.1 Quick Start
1. Open the packing material, find the packing list, and ensure that all the necessary
components are present for the Intel NetStructure
®
MPCMM0002 CMM.
2. Take the MPCMM0002 CMM to the chassis in which it will be installed.
3. Following standard ESD protection procedures, remove the CMM from its anti-static
bag.
4. Insert the management module into the card guides for the dedicated CMM slot.
Follow the chassis manufacturer’s or system vendor’s directions for the proper
orientation of the CMM.
5. As the CMM is being pushed into the slot, keep the ejector handle open until it
engages with the card guide. Ensure the alignment pins on the faceplate engage
the receptacles on the card cage. When the ejector handle engages, rotate the
ejector handle toward the faceplate until the card is fully seated.
6. Use a screwdriver or pair of pliers to tighten the retention screws on both ends of
the faceplate.
7. If the chassis power is on, the CMM will turn on automatically.
8. Connect the appropriate cables to the front or rear serial port, LAN ports. Connect
the telco alarm connector, if desired.
9. If a second CMM is to be installed in the chassis, follow the same instructions in this
procedure.
To remove the CMM:
1. Loosen the retention screws with a screw driver (Type#1 Philips head screw
driver).
2. Pull the ejector away from the faceplate (unlatch condition for ejector) enough to
ensure that the blue LED on the faceplate begins to flash. At this stage, the CMM
remains attached to the chassis (the backplane connector of CMM is still mated
with the chassis’s connector).
3. When the blue hot swap LED turns solid blue, pull the ejector farther out in order to
eject the CMM from the chassis.
Note: The hot swap LED will turn solid blue only when the redundancy feature is fully
enabled.

Module Components—MPCMM0002 CMM
4.3 Memory
The CMM has a SODIMM (Small Outline Dual Inline Memory Module) socket on board.
The SODIMM is populated with a 128 MByte unbuffered memory module.
The CMM also has four separate 16 MByte flash modules. These are Intel
®
E28F128
flash memory modules. Each memory module has multiple lockable regions within the
flash.
4.4 Ethernet
The CMM has two Intel
®
82551QM Fast Ethernet Multifunction Controllers with
integrated media access controllers and physical interfaces. The output from each of
these chips is passed to a dedicated multiplexing device (mux), the SN74CBT16124.
Each mux can be individually controlled to send the Ethernet signals to one of three
destinations: the front panel, an optional RTM connection, or a separate backplane
connection. Separate magnetics (six total) provide magnetic coupling for the 10BASE-T
or 100BASE-TX signaling commonly associated with 10/100 MByte/s Ethernet.
In Figure 3, “CMM Top View Layout” on page 16, the four magnetics for the RTM and
backplane connections are at the bottom of the board. The two magnetics for the front
panel are integrated into the front panel RJ-45 connectors.
4.5 Serial Port UARTs
The UART (Universal Asynchronous Receiver/Transmitter) controller on the CMM board
is a Texas Instruments* TL16C752B dual UART chip. The first serial port is connected to
an RJ-45 connector on the front panel; the second serial port is passed to the rear of
the card for an optional RTM connection. Full modem hardware signals are passed
through to the RTM.
The UART driver provides 15 kV of ESD protection (8 kV contact, 15 kV air discharge).

4.6 FPGA
The MPCMM0002 CMM has two redundant field-programmable gate arrays (FPGAs) on
board. These two Xilinx* Spartan* II XC2S200 FPGAs have identical internal design,
but different addresses. A brief summary of the FPGA functions is shown in Table 3.
4.7 Redundancy and Hot Swap CPLD
A Xilinx XC95144XL CPLD is used on the CMM to control the redundancy failover logic,
Hot Swap logic, FPGA control, and address decode for simple devices on the CMM. This
CPLD also contains the PCI arbitration circuitry for the 80321 processor and the
Ethernet controllers.
4.8 Watchdog Timer
A Maxim* MAX6374KA-T watchdog timer is used to protect against CPU lockups. The
CMM firmware strobes the watchdog periodically; if the CPU fails to strobe the
watchdog within a given time interval, the watchdog sends a signal to the CPLD that
forces the CPU to reset. This allows the processor to automatically recover to a known
good state in the case of lockup.
Note: If the watchdog timer fires, the IPMB signals are not affected by the CPU timer reset.
The other CMM automatically takes over and manages the chassis.
4.9 Real-Time Clock
The CMM time-stamps certain events as they occur within the system, particularly
entries into the System Event Log (SEL). A Dallas Semiconductor* DS1307 real-time
clock provides this capability.
To avoid losing the current time, the CMM provides independent power to the DS1307
with an on-board battery (size CR2032). The battery provides approximately five years
of run time for the clock in case of a power failure or if the CMM is removed from a
chassis.
Batteries have limited shelf lives. After many years in storage, a battery may not be
able to hold a charge. To supplement the battery, a super capacitor (SCap) is also
provided on the CMM; this provides a mechanism to get up to two hours of backup
power for the clock in case of a power failure. Though the SCap will not hold a charge
for even a full day, the ability to power the clock circuit during a power failure even
after years in storage is a reliability feature of the CMM.
The battery and SCap are both diode-OR’d to ensure that either one can supply the
power for the clock without being affected by the other backup power source.

Module Components—MPCMM0002 CMM
4.10 ADM1026 Controller
An Analog Devices* ADM1026 controller monitors the on-board voltages and manages
the thermal sensors. The processor communicates with the ADM1026 through an I
2
C
bus.
4.11 Hot Swap Controller
The CMM uses an LTC4250AH* Hot Swap controller to ramp voltages and watch for
over-current conditions. If the CMM draws more than 2.5 A for more than 500 µs, the
Hot Swap controller terminates.
The Hot Swap controller waits for the enable signals (short pins tied to each return) to
connect before ramping up the circuitry on the CMM. Similarly, if a CMM is pulled out of
the system, the Hot Swap controller immediately cuts power to the board.
4.12 Ride-Through Support
Many carriers require equipment to survive a 5 ms period without any power in order to
survive power glitches due to short circuit, power switchovers, etc. Section 4.1.4.3 of
the PICMG 3.0 specification requires boards to survive this 5 ms drop-out and
recommends that other chassis elements also have capability to ride through these
transients.
The MPCMM0002 CMM module meets this requirement. The CMM will survive the zero
volt transient described in Table 4-4 of the PICMG 3.0 specification. Large bulk
capacitors next to the DC-DC power converters provide this hold-up capacity.
4.13 IPMB Isolation Logic
In a carrier-grade system it is important to prevent cascaded failures; that is, a failure
in one element that affects other system elements and causes them to fail or lose
significant functionality. A shared bus is more sensitive to a single item impacting other
elements than a simple point-to-point system. This is one reason the MPCMM0002 CMM
chassis management module implements the hybrid dual IPMB star topology outlined in
Section 6.1, “IPMB Routing” on page 28.
Some IPMB channels are dedicated links between the CMMs and an individual blade;
this type of link is called a star. Some IPMB channels are shared among several devices,
and this type of link is called a bus. The star and bus elements have different isolation
logic in the CMM.
4.13.1 Dual Star IPMB Isolation
The dual star IPMBs on the MPCMM0002 CMM use MOSFET-controlled isolators to
disconnect all the radial IPMB signals automatically if power fails on a CMM. The
isolation circuit is pictured in Figure 5. The hardware ensures that the CMM is isolated
from the dual star IPMBs if power fails.
