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.

3.13.1 Configuring Network Attributes Using Mellanox Onyx (MLNX-OS)

The procedures described in this chapter assume that you have already installed and powered on the system according to the instructions in this document. The system comes with a pre-configured DHCP. If you wish to disable it, refer to Disable Dynamic

Host Configuration Protocol (DHCP). In case a manual configuration is required, please refer to the instructions in Manual Host Configuration.

3.13.1.1 Manual Host Configuration

To perform initial configuration of the system:

Step 1. Connect a host PC to the Console RJ45 ( ) port of the system, using the supplied harness cable (DB9 to RJ45). Make

sure to connect to the Console RJ45 port and not to the (Ethernet) MGT ( ) port.

Step 2. Configure a serial terminal program (for example, HyperTerminal, minicom, or Tera Term) on your host PC with the settings described in the table below. Once you perform that, you should get the CLI prompt of the system.

8.2 Thermal Threshold Definitions

Three thermal threshold definitions are measured by the Spectrum ASICs, and impact the overall switch system operation state as follows:

•

Warning – 105°C: On managed systems only: When the ASIC device crosses the 100°C threshold, a Warning Threshold message will be issued by the management software, indicating to system administration that the ASIC has crossed the Warning threshold. Note that this temperature threshold does not require nor lead to any action by hardware (such as switch shutdown).

•

Critical – 120°C: When the ASIC device crosses this temperature, the switch firmware will automatically shut down the device.

•

Emergency – 130°C: In case the firmware fails to shut down the ASIC device upon crossing its Critical threshold, the device will auto-shutdown upon crossing the Emergency (130°C) threshold.

For thermal threshold definitions in Cumulus Linux, see Configuring Net-SNMP Event Notification Traps in the Cumulus Networks

Notes:

TFAULT is an open collector/drain output, which should be pulled up with a 4.7k-10k Ohms resistor on the host board if intended for use. Pull up voltage should be between 2.0V to Vcc + 0.3V. A high output indicates a transmitter fault caused by either the TX bias current or the TX output power exceeding the preset alarm thresholds. A low output indicates normal operation. In the low state, the output is pulled to <0.8V.

Laser output disabled on TDIS >2.0V or open, enabled on TDIS <0.8V

Should be pulled up with 4.7kΩ-10kΩ on host board to a voltage between 2.0V and 3.6V. MOD_ABS pulls line low to

indicate module is plugged in.

LOS is open collector output. Should be pulled up with 4.7kΩ-10kΩ on host board to a voltage between 2.0V and 3.6V.

Logic 0 indicates normal operation; logic 1 indicates loss of signal.

8.3.3 RJ45 to DB9 Harness Pinout
