2 Introduction
Mellanox Spectrum® based 1U switch systems are an ideal spine and Top of Rack (ToR) solution, allowing maximum flexibility, with
port speeds spanning from 10Gb/s to 100Gb/s per port, and port density that enables full rack connectivity to any server at any speed.
The uplink ports allow a variety of blocking ratios that suit any application requirement. Powered by the Mellanox Spectrum ASIC,
the systems carry whopping switching and processing capacities in a compact 1U form factor.
Keeping with the Mellanox tradition of setting performance record switch systems, the Mellanox Spectrum-based systems introduce
the world’s lowest latency for 100GbE switching and routing elements, and do so while having the lowest power consumption in the
market. They enable the use of 10, 25, 40, 50 and 100GbE in a large scale without changing power infrastructure facilities.
The Mellanox Spectrum-based 1U switch systems are a part of Mellanox’s complete end-to-end solution, which provides 10GbE
through 100GbE interconnectivity within the data center. Other devices in this solution include ConnectX®-4 based network interface
cards, and LinkX® copper or fiber cabling/transceivers. This end-to-end solution is topped with NEO, a management application that
relieves some of the major obstacles standing in the way when deploying a network. NEO enables a fully certified and interoperable
design, speeds up time to service and RoI. The systems introduce hardware capabilities for multiple tunneling protocols that enable
increased reachability and scalability for today’s data centers. Implementing MPLS, NVGRE and VXLAN tunneling encapsulations in
the network layer of the data center allows more flexibility for terminating a tunnel by the network, in addition to termination on the
server endpoint.
While Mellanox Spectrum provides the thrust and acceleration that powers the switch systems, they get yet another angle of
capabilities, running with a powerful x86-based processor, which allows them to not only be the highest performing switch fabric
elements, but also grants them the ability to incorporate a Linux running server into the same device. This opens up multiple
application aspects of utilizing the high CPU processing power and the best switching fabric, to create a powerful machine with
unique appliance capabilities that can improve numerous network implementation paradigms. The Mellanox Spectrum-based 1U
switch systems support the Open Network Install Environment (ONIE) for zero touch installations of network operating systems.
While all Ethernet systems can be purchased preloaded with Mellanox Onyx (MLNX-OS), the SN2000 switches (in both the 100GbE
and the 40GbE versions) are offered, in addition, with Cumulus Linux support, as an alternative operating system. For a full list of all
available ordering options, see Ordering Information.

internal parts.
Multiple Power Inlets
Risk of electric shock and energy hazard. The PSUs are all independent. Disconnect all power supplies to ensure a powered
down state inside of the switch platform.
During Lightning - Electrical Hazard
During periods of lightning activity, do not work on the equipment or connect or disconnect cables.
Copper Cable Connecting/Disconnecting
Copper cables are heavy and not flexible, as such they should be carefully attached to or detached from the connectors. Refer to
the cable manufacturer for special warnings/instructions.

3.3 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.
Air Flow Direction Marking - Power Side Inlet to Connector Side Outlet
Connector (front) side inlet to power side outlet - marked with red power supplies/fans FRUs’ handles.
Air Flow Direction Marking - Connector Side Inlet to Power Side Outlet
The table below provides an air flow color legend and respective OPN designation.
Direction Description and OPN Designation
Connector side inlet to power side outlet. Red latches are placed on the power inlet
side.
OPN designation is “-R”.
The following information does not apply to SN2100/SN2010. In the SN2100/SN2010 systems, the fan units are non-
replaceable.

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.

Rack Rail Kit Parts
Prerequisites:
Before mounting the system to the rack, select the way you wish to place the system. Pay attention to the airflow within the rack
cooling, connector and cabling options.
While planning how to place the system, consider the two installation options shown in the figure below, and review the following
points:
Make sure the system air flow is compatible with your installation selection. It is important to keep the airflow within the rack
in the same direction.
Note that the part of the system to which you choose to attach the rails (the front panel direction, as demonstrated in Option 1
or the FRUs direction, as demonstrated in Option 2) will determine the system’s adjustable side. The system’s part to which
the brackets are attached will be adjacent to the cabinet.
The FRU side is extractable. Mounting the rack brackets inverted to the FRU side (Option 2) will allow you to slide the FRUs,
in and out.

To mount the system into the rack:
Attach the left and right rack mount rails (A) to the switch, by gently pushing the switch chassis’ pins through the slider key
holes, until locking occurs.
Secure the chassis in the rails by screwing 2 flat head Phillips screws (E) in the designated points with a torque of 1.5±0.2
Nm.
At least two people are required to safely mount the system in the rack.

Attaching the Rails to the Chassis
Attach the left and right rack mount brackets (B) to the switch, by gently pushing the switch chassis’ pins through the slider
key holes, until locking occurs. Secure the system in the brackets by screwing the remaining 2 flat head Phillips screws (E) in
the designated points with a torque of 1.5±0.2 Nm.
Attaching the Brackets to the Chassis
Install 8 cage nuts in the desired slots of the rack: 4 cage nuts in the non-extractable side (in the top and bottom holes only)
and 4 cage nuts in the extractable side.
Installing the Cage Nuts
While your installation partner is supporting the system’s weight, perform the following steps:
Mount the system into the rack enclosure, and attach the brackets installed on the system to the rack’s posts. Secure the
brackets to the rack’s posts by inserting four M6 screws in the designated cage nuts, as described in the figure below. Do not
tighten the screws yet.
While each rack U (unit) consists of three holes, the cage nut should be installed vertically with its ears engaging the
top and bottom holes only.
