1Installation
Installation and initialization of the chassis is a simple process requiring attention to the
normal mechanical, power, and thermal precautions for rack-mounted equipment. Your
chassis comes only with the power supplies and fans pre-installed. The rest of the open-
ings are populated with blanks. All of the leafs, spines, and management modules come
shipped in a separate package.
The chassis requires initial configuration to get the chassis and Fabric management up
and running through remote management. See the Installation Guide that is packed in the
box for the instructions to make the initial configuration.

Before you install your new SX6518 series 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 damage that may have occurred during shipping.
It is highly recommended that the installation sites be as isolated as possible from all
sources of radio transmissions and electrical interference.
It is highly recommended that the installation site building be equipped with a light-
ning rod.
It is highly recommended that the installation site be equipped with smoke detectors
and a fire alarm warning system.
The system requires a KVA rated UPS system. It is recommended that a UPS system
be installed to protect the equipment in the event of unexpected power failure.
Make sure that the outlets and circuits will not be overloaded. Spread out the load over
at least two or three circuits or use a 3 phase circuit.
If anything is damaged or missing, contact your customer representative immediately.

1.4 Leaf Package Contents
The leafs are ordered by the customer and are shipped 4 to a box. The customer will
receive as many boxes as needed to fill the order.
1.5 Spine Package Contents
The spines are shipped 3 to a box. The customer will receive as many boxes as needed to
fill the chassis with a full complement of spines.
1.6 Management Package Contents
The package includes:
• all of the management modules ordered by the customer
•1 RJ45 to DB9 harness for each management module received
1.7 Physical Installation
The switch platform uses 18U of rack space in a standard 19” rack, 16U for the chassis
and 2U for the shelf. The switch ships from the factory with mounting holes on the spine
side. There are upper brackets to connect the leaf side to the rack near the top of the chas-
sis, and there are two lock-down bars to secure the chassis to the shelf. The weight of the
switch is supported from underneath the unit by the shelf.
This chassis can be installed in standard 19” racks that have between 65cm and 80cm
between the vertical supports of the rack. Make sure that a fully populated rack including
cables will have sufficient air flow for cooling.
The rack mounting holes conform to the EIA-310 standard for 19-inch racks. Guaran-
tee 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 crucial 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.
Insert the bottom spine board first.
Warning: This equipment is very heavy. Safety is the first concern. Make sure that
adequate manpower and proper equipment is used for transporting and moving the
chassis.
The fully loaded chassis weighs:
212.36 kg (468 LBS) full configuration
90 kg (199 LBS) empty configuration
112 kg (247 LBS) shipped configuration
Choose a rack which is able to support the mechanical and environmental characteris-
tics of a fully populated switch chassis.

1.7.1 Starting with the Rack
Rack Recommendation
1.7.1.1 Preparing the Rack
The rack may need to be modified to accommodate the SX6518 chassis. The distance
between the vertical supports must be between 65 and 80cm.
Figure 1: Distance Between the Vertical Supports
1.7.2 ESD Connection
Before starting any procedure on the SX6518 switch system:
1. Put an ESD prevention wrist strap on your wrist, and make sure there is good contact
between your body and the strap.
2. Plug the other end of the wrist strap to a valid ground. Make sure that this is a tight
fit.
Due to the space required by up to 324 connector cables Mellanox recommends a rack
that is 100 cm long and 80cm wide. This will allow for proper cable management and
enough ventilation to properly cool the chassis.
This edge of the shelf must be as
close as possible to the inside of
the door when closed.
Vertical Supports
Between 65 and 80 cm.

1.7.3 Installation Procedure
1.7.3.1 Requirements
You will need:
1.7.3.2 Installation and Cable Management Kit Parts
• Parts included in the installation kit:
Installing the chassis will be a lot easier if you can remove the sides of the rack.
You will need a fork lift, to move and insert the chassis into the rack.
• #2 phillips screwdriver • #3 phillips screwdriver
• a fork lift • a grounding lug
• measuring tape • ground wire of sufficient length and gauge to properly ground the
chassis
The installation will be much easier with a power screwdriver.
It is recommended to use AWG6 or 4mm diameter wire for grounding purposes.
It is recommended to have at least two people for the duration of the installation proce-
dure. Use a mechanical lift to raise this chassis. If not, use enough manpower to ensure
the safety and wellbeing of all of the people involved in the installation.
