Introduction to Mellanox SX67X0/SX6710G Systems
Rev 2.0 11Mellanox Technologies
1 Introduction to Mellanox SX67X0/SX6710G Systems
1.1 Overview
The SX67X0/SX6710G systems provide the highest performing fabric solution in a 1U form fac-
tor 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 2048 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 System Installation and Initialization
Installation and initialization of the system require attention to the normal mechanical, power,
and thermal precautions for rack-mounted equipment.
The installation procedure for the system involves the following phases:
1. Follow the safety warnings in Section 2.1.
2. Pay attention to the air flow consideration within the system and rack - refer to “Air Flow” on
page 15.
3. Make sure that none of the package contents is missing or damaged - see “Package Contents”
on page 16.
4. Mount the system into a rack enclosure - see “Mounting Options” on page 20.
5. Power on the system - refer to “Initial Power On” on page 34.
6. Perform system bring-up - see “System Bring-Up” on page 35.
7. [Optional]: FRU replacements are described in Section 2.10 on page 41.
2.3 Air Flow
Mellanox systems are offered with two air flow patterns:
• Power (rear) side inlet to connector side outlet - marked with blue power supplies/fans-
FRUs’ handles, as shown in Figure 3.
• Connector (front) side inlet to power side outlet - marked with red power supplies/fans
FRUs’ handles, as shown in Figure 4.
The rack mounting holes conform to the EIA-310 standard for 19-inch racks. Take
precautions to guarantee proper ventilation in order to maintain good airflow at ambi-
ent temperature.
Unless otherwise specified, Mellanox products are designed to work in an environ-
mentally controlled data center with low levels of gaseous and dust (particulate) con-
tamination.
The operation environment should meet severity level G1 as per ISA 71.04 for gas-
eous contamination and ISO 14644-1 class 8 for cleanliness level
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.

2.5 Battery Backup Unit (BBU) Installation for SX6720
A new Battery Back-up Unit (BBU) will be approximately 30% 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.
2.5.1 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 7.
Step 3. Slide the module back into the chassis.
A BBU-compatible system is available by ordering an SX6720 system with an appro-
priate license.
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
• The BBU maximum storage temperature is 25°C.
• The WebUI might show a fully charged battery, despite a possible 2-3% deviation.
Nevertheless, it is still safe to discharge the battery for up to 5 minutes.
• A BBU that has not been used for six months or longer past ts printed manufactur-
ing 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.
Do not insert the battery unit into the switch during its discharge.
