1 Overview

Mellanox MTS3600 switch systems provide the highest performing fabric solution by delivering high band-

width and low latency to Enterprise Data Centers, High-Performance Computing and Embedded environ-

ments. Networks built with MTS3600 systems can carry converged traffic with the combination of assured

bandwidth and granular quality of service. Built with Mellanox’s 4th generation InfiniScale® IV InfiniBand

switch device, MTS3600 systems provide up to 40Gb/s full bidirectional bandwidth per port. With 36 ports,

these systems are among the densest switching systems available. These stand-alone switches are an ideal

choice for top of-rack leaf connectivity or for building small to medium size clusters.

The switch comes pre-installed with all necessary firmware and configured for standard operation within an

InfiniBand fabric, and requires an InfiniBand compliant Subnet Manager running from one of the hosts. All

that is required for normal operation is to follow the usual precautions for installation and to connect the

switch to the HCAs. Once connected, the Subnet Management software automatically configures and begins

utilizing the switch.

It is recommended that Mellanox OpenFabrics software package be installed on all nodes connected to the

MTS3600. The software package provides a subnet manager and network management tools as well as con-

nectivity software for servers and storage, and is available on the Mellanox web site. See Chapter 3 for more

information.

Basic installation, hot-swapping components and hardware maintenance is covered in “Installation and

Basic Operation” on page 2.

The installer should use a rack capable of supporting the mechanical and environmental characteristics of a

fully populated platform.

Note: The switch platform can be either front or rear mounted. The notion of “front” and “back” is arbi-

trary; however, “rear” is used consistently in this manual to refer to the side of the switch with the

InfiniBand and Ethernet connectors.

2.2.2.1 Installing the Switch in the Rack

Tools needed:

Phillips Screwdriver

ESD Strap

ESD mat

Parts included in the installation kit:

Figure 5: Rack Installation Kit Support Parts

Procedure

1. Place the ESD mat on the Floor where you will be working and put on the ESD strap. Make sure the

ESD strap is touching your skin and that the other end is connected to a verified ground.

2. Choose which way you want the switch to slide out of the rack. Either the side with the power

supply units can slide out or the side with the IB connectors can slide out.

The rack mounting holes conform to the EIA-310 standard for 19-inch racks. Take pre-

cautions to guarantee proper ventilation for air intake at the front of the chassis and

exhaust at the rear in order to maintain good airflow at ambient temperature. Cable

routing in particular should not impede the air exhaust from the chassis.

Figure 6: Which Side of the Rack Do You Want the Connectors?

Do you want the connector side recessed in the rack to allow for larger cable bending radius?

Will the connector side be recessed past other equipment in the rack and will this be problematic?

3. Take the 2 mounting plates and screw them to the switch with the notched side up.

Note: They are right hand and left hand. Place them with the notch at the top.

4. Place them on the end of the switch that you want to slide out. Use two of the flat head screws

for each mounting plate. There are three sets of holes in the mounting plate to choose from.

You can choose any of the pairs, make sure that you pick the same pair for both mounting

plates. This allows you to reduce or increase the distance the switch is recessed into the rack.

5. Clip the nuts into the holes in the rack you will be using to connect the mounting plates.Check

that both sides of the switch are in the same position number on the rack.

6. Take the 2 rail slides and screw them to the switch. Use two of the flat head screws for each

rail slide.

The distance between the rack and the door will be as little as 4 cm on one side of the

rack and as much as 18 cm on the other side of the rack. Keep in mind that there can be

as many as 36 cables connected to the switch.

3.2.1 Instructions for Reprogramming Over the InfiniBand Network

To update an MT48436 InfiniScale IVswitch device having a specific GUID (for example,

0x00000006660abcd0) or LID, the following are the recommended steps to update the device firmware.

1. Make sure all subnet ports are in the active state. One way to check this is to run opensm, the Subnet

Manager.

[root@mymach]> /etc/init.d/opensmd start

opensm start [ OK ]

2. Make sure the local ports are active by running ‘ibv_devinfo’.

3. Obtain the device LID. There are two ways to do that:

I. Using the “mst ib add” command:

The “mst ib add”runs the ibdiagnet tool to discover the InfiniBand fabric and then lists the discovered IB

nodes as an mst device under /dev/mst/ directory. These devices can be used for access by other MFT

tools.
