1 Overview
The InfiniScale® III M2401G 20Gb/s InfiniBand blade switch I/O module for PowerEdge M-
Series provides a high bandwidth, low latency, low power fabric for Enterprise Data Center and
High-Performance Computing environments. Based on the third generation InfiniScale® III Infini-
Band switch device, the platform delivers an ideal balance between cost and performance. When
used in conjunction with ConnectX® InfiniBand dual port I/O cards clustered data bases, parallel-
ized applications and transactional services applications will achieve significant performance
improvements resulting in reduced completion time and lower cost per operation.
The switch platform comes pre-installed with all necessary firmware, and configured for standard
operation within an InfiniBand fabric, and requires an InfiniBand compliant Subnet Manager run-
ning from one of the hosts. All that is required for normal operation is to follow the usual precau-
tions for installation and connection from the switch to the HCAs or other switches. 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 con-
nected to the M2401G. The software package provides a subnet manager and network management
tools as well as connectivity software for servers and storage, and is available on the Mellanox web
site. See “Cluster Management and Firmware” on page 14. for more information.
Basic installation, hot-swapping components and hardware maintenance is covered in “Installa-
tion and Basic Operation” on page 9.
The M2401G switch has a Hot Swap controller and a PSOC Management IC.

1.1 InfiniBand Connectors
InfiniBand connectivity has 8 microGiGa connectors through the front panel. The remaining 16
interfaces are through the AirMax Midplane Connector out the back of the switch. Figure 1 shows
the front 8 ports.
Each of the InfiniBand ports has two LEDs located next to the connector. The green LED, when lit,
indicates that a valid physical connection to the other system (switch or HCA port) exists. The yel-
low LED when lit, indicates that the Subnet Manager is running and a valid data link exists. The
yellow LED illuminates when the InfiniBand network is discovered over the physical link. A valid
data activity link without data transfer is designated by a constant yellow LED indication. A valid
data activity link with data transfer is designated by a blinking yellow LED indication. If the LEDs
are not active, either the physical link or the logical link (or both) connections have not been estab-
lished.
Figure 2: Physical and Logical Link Indication LEDs
1.2 Switch Status Lights
The switch Status lights indicate whether the switch is receiving power from the chassis, and the
state of the switch.

2.2.3 Installing the Mellanox M2401G Switch Into the Dell Chassis
Note: Make sure the Chassis is stable on a solid floor and that the Chassis is filled from the bot-
tom up. This will keep the center of gravity as low as possible reducing risk of tipping.
Note: The M2401G IOMs are only to be installed in Fabric B or Fabric C slots, and at least one
blade must have a matching ConnectX I/O card installed to support data flow. Within each fabric
type, you must install a module in the fabric's channel 1 slot before installing a module in the
fabric's channel 2 slot. For example, you must install a module in slot C1 before installing a
module in slot C2. Modules may be installed in Fabric B and C independently (you do not need
to install modules in Fabric B before installing modules in Fabric C slots). Refer to the Dell
PowerEdge M1000e Hardware Owners Manual for more information.
1. Follow the instructions in Section 2.2.1 or Section 2.2.2 to remove an old switch or a Blank
cover plate.
2. On the new switch, push the red latch release button.
3. Pull the lever forward until the lever is perpendicular to the front panel.
4. Push the switch into the slot until the latching mechanism is against the bar.
5. Push the lever on the latching mechanism up, making sure that the latching mechanism catches
the locking bar. The lever should now be parallel to the front panel.
6. Check the indicator lights to make sure the switch has power.
The installer should use a rack cable to support the mechanical and environmental characteristics of
a fully populated switch platform Chassis.
The rack mounting is designed to fit the PowerEdge Chassis. Take precautions 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 partic-
ular should not impede the air exhaust from the chassis.
2.3 Power Connections and Initial Power On
Caution: The switch platform will automatically power up when AC power is applied. There is no
power switch. Immediately upon closing the latching mechanism check to make sure that the
green switch LED is lit.

2.4 InfiniBand Cable Installation
All cables can be inserted or removed with the unit power on. To insert a cable, press the connector
into the port receptacle until the connector is firmly seated. The green LED indicator below each
port will light when the physical connection is established (that is, when the unit is powered on and
a cable is plugged into the port with a functioning port plugged into the other end of the connector).
After plugging in a cable, lock the connector using the latching mechanism particular to the cable
vendor. The yellow LED will light if the subnet manager is running (non blinking indicating that no
data is being transferred yet). When a logical connection is made the yellow LED will blink signi-
fying data is being transferred.
To remove, disengage the locks and slowly pull the connector away from the port receptacle. Both
LED indicators will turn off when the cable is unseated.
Care should be taken not to impede the air exhaust flow through the chassis.
Note: Cable lengths should be used which allow for routing horizontally around to the side of the
chassis before bending upward or downward in the rack.

3Cluster Management and Firmware
3.1 Network Management and Clustering Software
Download and install, on all nodes, the Mellanox OpenFabric software package for Linux, Win-
dows, or other operating systems from the Mellanox software website:
http://www.mellanox.com > Downloads > InfiniBand SW/Drivers
This software package provides connectivity for server and storage systems utilizing High Perfor-
mance Computing (HPC) or enterprise data center (EDC) applications across an InfiniBand fabric.
It also provides a Subnet Manager for simple network configuration and network administration
and diagnostic tools for network management.
3.2 Updating Firmware
The switch is delivered with the latest Firmware available at the time of production. New firmware
versions will be posted on the Mellanox firmware download page. Firmware can be updated in-
band using the Mellanox Firmware Tools (MFT).
You will need the Mellanox Firmware Tools package available in MLNX_OFED to update firm-
ware for this switch. It also can be downloaded from:

3.2.1 Instructions for Reprogramming Over the InfiniBand Network
To update an MT47396 InfiniScale III switch devices having a specific GUID (for example,
0x00000006660abcd0) or LID, the following are the recommended steps to update the device firm-
ware.
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.
