2 HW Modules
Figure 2 : R9100 HW modules
2.1 FPGA and SFP/QSFP
he ADM-R9100 AD01474 configurable network switch accelerator is composed of 3 Alpha-Data-designed circuit
boards. he FPGA board (AD01474) attaches directly to an SFP breakout board (AD01475) and is cabled to two
QSFP boards (AD01476).
he AD01474 is fitted with an AMD Virtex UltraScale+ VU2P, an ultra-low latency FPGA device.
he low-latency lanes are driven by the Xilinx G F transceivers. he ADA-R9100 has been tested at both
10.3125Gbps and 25.78125Gbps for each low latency lane.
he SFP/QSFP connections at the front are rated at Power Level II (1.5W max) for SFP+ ports, and Power Level
7 (5W max) for QSFP28 ports.
he system is modular, and the AD01474/75/76 subsystem is fitted on a detachable tray for serviceability.
2.2 CPU board
Featuring AMD’s ROMED4ID-2 server grade mini-I X motherboard, the R9100 supports all the typical services
like Web, KVM, SSH, LDAP, RADIUS services, through its BMC processing subsystem.
Remote access with video support is through the KVM server, and it can be remotely launched from the available
web server when the BMC is on (on standby too).

1 PWR: Power ON/OFF button/indicator. his is a momentary action pushbutton with LED indication. he
two independent processing systems (ROMED4ID-2 and AD01474) remain on standby until the button is
pressed. he indicator lights up when the system is powered on.
Note:
his is an ACPI-compliant operating system, when the power button is used to shut the system down, the
operating system performs a graceful shut down and the system power is turned off. If the button is pushed
and held for 3-5s, an immediate shutdown is performed.

Now, fit the mounting rail (4), but not too tight (allow some horizontal movement) and slide it all the way back for
maximum extension, then slide the unit in the rack until solidly supported by the previously installed rear brackets
(5). Check the slack and adjust the rails for a good fitting of the front panel (as depicted below):
Figure 6 : Adjusting the rails extension to the rack depth
Screw up the front panel for a tight fit. Finally, secure the rails by tightening up the screws that were not fully
tightened in step 3. hat is the unit secured in the rack.
Note:
Always try to install the heaviest equipment near the bottom of the rack to prevent the rack from tipping over
when the chassis is pulled out on its rails.
Note:
When possible, install anti-tip legs to the rack to also prevent tipping, or some other anti-tip device which
protects the enclosure from tipping when servers and shelves are extended.

V1.2 - 10th October 2023
6 Powering the System Up
he R9100 is equipped with a 1+1 redundant power supply unit (RSPU), and as such both redundant modules
need to be sourced for a reliable 24/7 server operation. For best performance, plug both modules into the power
lines before turning the system on (see Section 3, items 15 and 16).
Note:
he RSPU does not have a power button, as this is handled by the ON/OFF button of the R9100 (ACPI
system)
he LED by the power socket on the RPSU will flash green if the operation of the corresponding module is
normal as soon as the RPSU is sourced (i.e.: plugged into the power lines), and it will turn red if a fault occurs.
he system ON/OFF switch is handled by a momentary pushbutton up front (see Section 3, item 1)
If the system is turned ON with one of the redundant modules disconnected (or faulty), an acoustic alarm will go
off. his means that the system has detected the condition of a missing module, and while it can normally
continue its operation with a single module, it is strongly recommended to plug the other module in (or hot-swap
it when it is faulty).
Note:
o disregard the alarm and shut it off, press the button in the middle of the RPSU once (see Section 3, item
14)
Contact [email protected] for extended information on the RPSU
6.1 Standby operation
he system will go into standby mode right after the RPSU has been sourced(i.e., plugged into the power lines).
he system is ready to be operated by then. See a summary of the active subsystems and interfaces below:

7 Feature Description
7.1 IPMI PCIe/I2C
here is an internal IPMI (PCIe/I2C) connection between the CPU System and the AD01474. It can handle the
IPMI commands locally from the CPU system as a local I2C device, or remotely through the IPMI tree by the
BMC/CPU Ethernet connections.
7.2 USB front/back
here is a common USB connection to the AD01474 that is split in two in the system: an internal USB connection
with no external port (between the CPU System and the AD01474), and a direct one with a USB B port in the
front panel of the R9100. he latter provides direct access for a quick local operation without needing to log into
the system (i.e.: operator with a laptop). For operating the one on the CPU side, login into Ubuntu is required.
he AD01474 utilizes the Digilent USB-J AG converter which is supported by the AMD software tool suite. he
two cases based on the connection are:
• Direct (external): Simply connect a USB B type cable between the front panel USB port (see Section 3,
item 5) and a host computer with Vivado installed. Vivado Hardware Manager will automatically recognize
the FPGA and allow you to configure it, and the SPI configuration Flash memory.
• Ubuntu (internal): Vivado Lab automatically detects USB connection to the AD01474 (see Section 9).
Both USB connections handle system monitor queries the FPGA programming/debugging. For system monitor
usage, see Section 8.
Note:
If USB(F) - front panel USB connection - is connected (see Section 3, item 5), then USB(B) (or internal USB
connection between the CPU System and the AD01474) will be lost momentarily until USB(F) is disconnected.
System Monitor queries in this case will need to be run through IPMI.
7.3 Management serial port (UART)
his is an RS2320-compliant serial port on an RJ45 connection (Section 3, item 7). his allows a connection with
a PC running a terminal emulation SW by means of a null-modem cable (also known as rollover cable, where all
the pins on one end (1-8) appear inverted with respect to the opposite end (8-1)). Same as the console port of
LAN Cisco switches/routers.
Note:
*WARNING! DO NOT connect an standard network cable to this RJ45 interface! this is an out-of-band
connection and connecting it to a network device may damage its internal circuits.
ypically, you can send/receive files and run system commands with a terminal emulation SW like Minicom. his
SW comes pre-installed with Ubuntu on the R9100.
o run Minicom on the R9100 and listen to incoming connections, execute the following commands:
sudo chmod 666 /dev/ttyS0
minicom -b 115200 -D /dev/ttyS0
Note:
Ubuntu will map the serial port to /dev/ttyS0 by default. he connection speed is 115200 bauds on the R9100.

Note:
You will need to deactivate flow control in Minicom by:

--> SW flow control --> OFF
Alternatively, run minicom -s to change parameters or modify the file minirc.dlf with the following lines to
make changes persistent:
pu port /dev/ttyS0
pu rtscts No
7.4 Input clock reference
Input SMA port for a 1PPS synchronization signal (Section 3, item 6). his can be used to synchronize with
external devices and instrumentation.
his clock is connected to the FPGA at pin H32, net name 1PPS_1V8 as shown in Complete AD01474 pinout.
