Before you install your new MTS3610 Chassis, unpack the system and check to make sure that all the parts

have been sent, check this against the parts list. Check the parts for visible damages that may have occurred

during shipping.

Note: If anything is damaged or missing, contact your customer representative immediately.

Physical Installation

Warning: This equipment is very heavy. Safety is the first concern. The fully

loaded chassis weighs ~350 lbs (155 kg). Make sure that proper manpower and

equipment are used for transporting and moving the chassis.

Note: You will need a mechanical lift, to move and insert the chassis into the rack.

This chassis can be installed in 19” racks with a maximum depth of 81cm.

The switch platform uses 20U of rack space in a standard 19” rack. The switch ships from the factory with

mounting racks on the front side. There are four threaded connectors on the top of the chassis for connecting

eye bolts. The four eye bolts are included in the installation kit. The chassis can be lifted using these four eye

bolts and a mechanical lift. The switch is supported from underneath the unit by a shelf.

Choose a rack which is able to support the mechanical and environmental characteristics of a fully populated

switch chassis as listed in the user manual.

Mellanox Technologies

Rev 1.2.2 2

Note: A 20U mounting space is required for proper installation of the switch platform.

The rack mounting holes conform to the IEA-310 standard for 19-inch racks.

Guarantee proper ventilation, by leaving 8cm (3”) of space to the front and rear

of the switch. This will ensure proper air flow through the chassis. This is cru-

cial for maintaining good airflow at ambient temperature. In particular, route

cables such that they do not impede the air into or out of the chassis.

ESD Connection

Before starting any procedure on the MTS3610 Switch system:

Step 1. Put an ESD prevention wrist strap on your wrist, and make sure there is good contact between

your body and the strap.

Step 2. Plug the other end of the wrist strap to the MTS3610 chassis ESD connector on the

front of the switch system or connect it to a valid ground. Make sure that this is a tight

fit.

Installing the Bottom Shelf

Step 1. Select the location in the rack. Try to keep the chassis as low as possible to keep the center of

gravity low.

Choose which way you want the chassis to face in the rack. Keep in mind that one side of the chassis can

have up to 324 cables connected. The other side of the chassis will have power cables. The distance between

the rack and the door will be small on one side of the rack as opposed to the other side of the rack.

Ground Connections

Make sure to connect the ground post to a valid electrical ground. Use a grounding lug and a ground wire of

sufficient capacity to safely convey a potential discharge. The chassis is concurrently grounded through each

of the PSUs. Only connect the PSU cords to properly grounded outlets. Do not rely on the PSU grounds. It is

absolutely necessary to connect the grounding post. Make sure the connections are solid and permanent.

Step 3. Screw the cable holder onto the rack using the screws provided.

Step 4. Repeat steps 1 to 3 for the second cable holder.

Powering Up the Switch Platform

Note: Make sure that the power cords are compatible with your outlets. Power cords for different countries

can be ordered from Mellanox.

Step 1. Plug in the power cords to the PSUs.

Step 2. Clamp each power cord to the chassis.

Each PSU has a clamp next to it, for supporting the power cord. Use this clamp to remove possible strain on

the PSU. The length of power cord between the clamp and the PSU must be less than 6” (15cm). See

Figure 11,“Electrical Cable Clamp”.

Step 3. Plug the other end of the power cord into a grounded outlet.

Note: It is recommended that the power to all of the power supplies be turned on at the same time.

Step 4. Repeat steps 1 to 3 for each of the remaining power supply units.

Note: A fully loaded MTS3610 switch system can draw 5.2 kW of power. Make sure that the outlets and

circuits will not be overloaded. Spread out the load over at least two or three circuits.

Figure 11: Electrical Cable Clamp

The switch system requires at least six PSUs to operate a fully populated platform. The seventh and eighth

PSUs provide a fail over protection mechanism such that the system will continue operating if one or more

of the PSUs fail. Connecting the PSUs to different AC lines provides AC fail over protection.

The system should continue to run and allow a hotswap of a defective PSU even if it has only six PSUs.

Step 5. As soon as a switch is plugged in, make sure that the green power LEDs on the PSUs

are on.

Step 6. Check the Status LEDs on all of the management modules and confirm that all of the

LEDs show status lights consistent with normal operation.

Warning: Any yellow status LEDs on any of the management modules is cause

for concern and must be dealt with immediately.
