Internally Managed vs. Externally Managed
The following table shows which switches come with a management CPU and which do not.
Managed switches can be upgraded from simple chassis management to full fabric management
by purchasing an additional license. For more information on buying a license see the user’s
manual.
Unmanaged switches are plug and play out of the box. All switches come with the latest firm-
ware burned on the Flash. Update the firmware on unmanaged switches in-band only. When new
firmware is available you will receive an email with the link to the Mellanox firmware download
site. The download site has the Mellanox firmware tool package and full instructions for updating
firmware.
All managed switches have internal chassis management and can manage up to 108 nodes.
FabricIT can support IB fabrics of up to 648 nodes. Managed switches need an initial configura-
tion before they will start working. See Table 3 for details.
Should your unmanaged switch have CONSOLE, Ethernet, and USB connectors, they will not
work. Only the I2C connector will work on unmanaged switches.
Table 3 - Switch Management by OPN
Family Managed /
Unmanaged Management Connections
IS5025 Unman-
aged No Management
Plug and play 
All firmware updates should be done in-band using Mellanox Firm-
ware Management Tools. 12C port access using MTUSB-1 device is
required for firmware updates if in-band burning is not possible.
IS5030 Managed RS232 cable DB9 to RJ45 included in the box to connect to host PC
for initial configuration of the switch. After initial configuration the
switch can be managed through the Ethernet using a remote connec-
tion.
This switch is capable of Fabric management for an unlimited num-
ber of nodes, with the purchase of Mellanox UFM.

tion.

Installing the Switch in the Rack
The procedure for installing the switch in a full rack while bringing the power cord across along
side of the switch can be found in the switch user manual.
The switch platform can be rack mounted and is designed for installation in a standard 19” rack.
The power side of the switch includes a hot-swap power supply module, a blank cover for an
optional second PSU for redundancy, and a hot-swap fan tray. There are two possible air flow
directions. Be sure that the switch air flow direction is compatible with your system, rack, and
PSUs. The connector side of the switch has the QSFP ports, system LEDs, and management con-
nection ports.
The switch platform contains auto-sensing 100 - 240 VAC connections for all possible PSUs.
The installer should use a rack capable of supporting the mechanical and environmental charac-
teristics of a fully populated platform.
Minimum and Maximum Rack Depth for this Switch
This switch can be installed in any standard 19”racks with depths of 380mm to 800mm.
The short switch with the MIS000079 Rail kit can only go into a 19” rack whose vertical sup-
ports are between 380mm and 500mm apart.
The standard depth switch uses the MIS000085 rail kit for installation in a 19” rack whose verti-
cal supports are between 500mm and 800mm apart.
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 air-
flow at ambient temperature. Cable routing in particular should not impede the
air exhaust from the chassis.
To use the IS50XX in a rack deeper than 500mm, order the IS50XX with the
standard depth, or order the MIS000083 rail kit. The both of these solutions will
allow you to install the switch in a 19” rack whose vertical supports are between
500mm and 800mm apart.

Installing the Switch in the Rack
Tools and Customer Supplied Parts
Figure 1: Rack Rail Kit Parts MIS00083/85
Make sure that the Rail kit is compatible with your rack.
For short depth switches, rail kit # MIS00083 is to be used for racks from 50cm to 80cm deep,
and rail kit # MIS00079 is to be used for racks from 38cm to 50cm deep including the iDataPlex
rack.
For standard depth switches rail kit # MIS00085 is to be used for racks from 60cm to 80cm deep.
Parts included in the rail kit:
• Phillips Screwdrivers #1 and #2 • Grounding screw
• ESD strap • Grounding wire sufficient to reach a valid ground.
•ESDmat
• 2 rails • 18 recessed flat head screws
• 2 rail slides • 8 caged nuts
• 2 brackets • 8 pan head screws M6

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 side of the switch you want even with the rack vertical support. Either the side
with the power supply units or the side with the IB connectors can be even with one of the
vertical rack supports. Short switches have the OPN character -B and are 1.716” (1U) H x
17.17” W x16.84” D 43.6mm X 436.2mm X 427.7mm. Standard switches have the OPN
character -S and are 1.716” (1U) H x 17.17” W x24.71” D 43.6mm X 436.2mm X 627.7 mm.
Things to consider before choosing where to mount the rails and rail slides.
•Airflow
• Configuration of already installed equipment
• Cable bending radius
The distance between the rack and the door can 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 con-
nected to the switch.
• Do you want the connector side recessed in the rack to allow for a larger cable bending
radius?
• Will the connector side be recessed past other equipment in the rack and will this be prob-
lematic?

Figure 7: Screwing on the Bracket
If you need to bring the Power cord from the other side of the rack, recess the
switch and run the Power cord through the bracket, also using the slot in the
rail slide. Go to “Passing the Power Cord From the Connector Side to the
Power Side” on page 61 for detailed instructions on routing the power cord
from the power side to the connector side.

4. Screw the rails onto the switch. Use 5 flat head screws to connect each rail to the switch.
Figure 8: Screwing on the Rail
5. Clip the 4 caged nuts into the holes in the rack you will be using to connect the rail slides.
Check that both sides of the switch, left and right, are the same level in the rack.
Figure 9: Inserting the Caged Nuts
6. Clip 4 more caged nuts into the holes in the rack you will be using to connect the brackets.
Check that both sides of the switch, power side and connector side, are at the same level in the
rack.
7. Using two of the bolts for each rail slide, install the rail slides.
8. Tighten the bolts to 9.2 Nm or 81.5 pound inches. If the power cable is on this side of the
switch, feed the power cable into the slot in the rail slide before screwing it to the vertical sup-
port.
The side of the switch with these brackets will be the side that is even with or very
close to the vertical rack support.

14.Plug in the power cables.
15.Check the Status LEDs and confirm that all of the LEDs show status lights consistent with
normal operation.
16.You can start connecting all of the cables to the switch.
Warning: Any yellow status LEDs is cause for concern and must be dealt with imme-
diately.
It can take up to 5 minutes to boot up, during which time the status LED may indicate
red.

Grounding the Switch
Check to determine if your local or national electrical codes require an external ground to all IT
components. If so, connect a ground wire to one of the casing screws and connect the other end to
a valid ground. If you choose to not use the ground screw, make sure that the rack is properly
grounded and that there is a valid ground connection between the chassis of the switch and the
rack. Test the ground using an Ohm meter.
Some national and/or local codes may require IT components to be bonded and exter-
nally grounded (not including the power cord ground). You must follow all national and
local codes when installing this equipment.

Configuring the Switch for the First Time
Externally Managed (Unmanaged) Switches
Unmanaged (Externally managed) switches, that is the IS5025 switches, do not get configured.
On unmanaged switches, the CONSOLE, Ethernet, and USB connectors are not found and if
existing do not work.
Figure 11: Externally Managed Management Interface
The unmanaged switches are Plug and Play and all firmware updates should be done in-band.
The I2C connection should only be used if the firmware image was corrupted to the point that the
regular firmware tools cannot successfully reburn the correct image.
When you install the switch, it comes with the latest firmware burned on the board. You will not
need to burn firmware unless you get notification from Mellanox that a newer version of firm-
ware for your switch has been released.
