1 Introduction to Mellanox SX67X0 Systems
1.1 Overview
The SX67X0 systems provide the highest performing fabric solution in a 1U form factor by
delivering up to 4Tb/s of non-blocking bandwidth with 200ns port-to-port latency.
These systems are the industry's most cost-effective building blocks for embedded systems and
storage with a need for low port density systems. Whether looking at price-to-performance or
energy-to-performance, these systems offer superior performance, power and space, reducing
capital and operating expenses and providing the best return-on-investment. The systems are an
ideal choice for smaller departmental or back-end clustering uses with high-performance needs,
such as storage, data base and GPGPU clusters.
Powerful servers combined with high-performance storage and applications that use increasingly
complex computations are causing data bandwidth requirements to spiral upward. As servers are
deployed with next generation processors, High-Performance Computing (HPC) environments
and Enterprise Data Centers (EDC) need every last bit of bandwidth delivered with Mellanox’s
FDR InfiniBand systems.
Built with Mellanox’s sixth generation SwitchX®-2 InfiniBand FDR 56Gb/s system device,
these standalone systems are an ideal choice for top-of-rack leaf connectivity or for building
small to extremely large sized clusters.
These systems enable efficient computing with features such as static routing, adaptive routing,
and advanced congestion management. These features ensure the maximum effective fabric
bandwidth by eliminating congestion.
The managed systems comes with an onboard subnet manager, enabling simple, out-of-the-box
fabric bring-up for up to 648 nodes. MLNX-OS® software delivers complete chassis manage-
ment of firmware, power supplies, fans, ports and other interfaces.
Mellanox’s edge systems can also be coupled with Mellanox’s Unified Fabric Manager (UFM®)
software for managing scale-out InfiniBand computing environments. UFM enables data center
operators to efficiently provision, monitor and operate the modern data center fabric. UFM
boosts application performance and ensures that the fabric is up and running at all times.
InfiniBand systems come as internally or externally managed. Internally managed systems come
with a CPU that runs the management software (MLNX-OS®) and management ports which are
used to transfer management traffic into the system. Externally managed systems come without
the CPU and management ports and are managed using firmware tools.
Mellanox's InfiniBand to Ethernet gateway, built with Mellanox's SwitchX®-2 based systems,
provides the most cost-effective, high-performance solution for data center unified connectivity
solutions. Mellanox's gateways enable data centers to operate at up to 56Gb/s network speeds
while seamlessly connecting to 1, 10 and 40GbE networks with low latency (400ns). Existing
LAN infrastructures and management practices can be preserved, easing deployment and provid-
ing significant return-on-investment.

2.2 Air Flow
Mellanox systems are offered with two air flow patterns:
• Connector (front) side inlet to power side outlet - marked with red labels on the power
supply side.
• Power (rear) side inlet to connector side outlet - marked with blue labels on the power
supply side as shown in Figure 4.
All servers and systems in the same rack should be planned with the same airflow
direction.
All FRU components need to have the same air flow direction. A mismatch in the air
flow will affect the heat dissipation.
Table 6 provides an air flow color legend and respective OPN designations.

2.4 Mounting Options
2.4.1 Battery Backup Unit (BBU) Installation for SX6720
If the BBU is deformed, leaking, corroded or visually damaged, replace it immediately
Do not use a BBU that was not provided by Mellanox Technologies
• A BBU that has not been used for two years or longer past ts printed manufacturing
date is unusable.
• A BBU that is older than five years, according to the printed manufacturing date,
has reached its "end of life" state and may not provide enough energy to handle the
platform.
• In case the battery should be replaced, software notifications will appear on a
monthly basis, starting three months before EOL time.
A new Battery Back-up Unit (BBU) will be approximately 50% charged when you receive it. In
case of a power outage, only a fully charged BBU can supply power of up to 5 minutes to the sys-
tem.
2.4.1.1 Installing the Battery
Step 1. Extract the power FRU module from the chassis of the switch by unlocking all latches
Step 2. Insert the BBU into the empty slot in the module by sliding it in and pushing the top end of it
down until it snaps into place, as illustrated in the left image of Figure 9.
Step 3. Slide the module back into the chassis.
2.4.1.2 Extracting the Battery
Step 1. Extract the power FRU module from the chassis of the switch by unlocking all latches.
Step 2. Press both release buttons simultaneously and lift the battery up to remove it, as illustrated in
the right image of Figure 9.
Step 3. Slide the module back into the chassis.

Planning the system’s placement in the rack
Before mounting the system to the rack, select the way you wish to place the system. Pay atten-
tion to the airflow within the rack cooling, connector and cabling options.
While planning how to place the system, review the following points:
• Make sure the system air flow is compatible with your installation selection. It is impor-
tant to keep the airflow within the rack in the same direction.
• In case there are cables that cannot bend within the rack or in case more space is needed
for cable bending radius, it is possible to recess the connector side or the FRU side by
3” or 4” (7.62 or 10.16cm) by optional placement of the system’s rails.
• The FRU side is extractable. Mounting the sliding rail inverted to the system will allow
you to slide the FRU side of the system, in and out.
Step 1. Install 10 cage nuts into the desired 1U slot of the rack: 4 cage nuts in the non-extractable side
and 6 cage nuts in the extractable side.
Step 2. Mount both of the outer rails (C) into the rack (as illustrated in Figure 11), and use 8 standard
pan-head screws (D) to fix them to the rack. Do not tighten the screws yet.
Step 3. If cable accommodation is required, rout the power cable and/or Eth cable through either of the
outer rails.
Step 4. Secure the switch to the left and right inner rails (A+B), by gently pushing the switch chassis’
pins through the slider key holes, until locking occurs. Secure the chassis in the inner rails
screwing the 2 flat head Phillips screws in the designated points.

Figure 13: Securing the Chassis in the Inner Rails
Step 5. Slide the switch into the rack by carefully pushing the inner rails into the outer rails installed on
the rack.
Step 6. When fully inserted, fix the switch by closing the remaining 2 screws in the middle and tighten-
ing the 8 screws inserted in Step 2 with a torque of Min 2Nm.
Figure 14: Sliding the Switch into the Rack
2.4.2.1 Removing the System from the Rack
To remove a unit from the rack:
Step 1. Unscrew the two M6 screws securing the front of the inner rails’ ears to the outer rails and to
the rack.
Step 2. Pull the unit out until braking is felt. For safety purposes, the locking mechanism will not allow
a complete removal of the unit at this stage.
Step 3.Press on the locking spring (appears in red in Figure 16) on both sides simultaneously, and con-
tinue pulling the unit towards you until it is fully removed.
