Tip: Read the Hardware Installation Manual if you install the switch for the first time.
Safety Notes
Do not install the switch in a wet place and keep it away from liquid.
Do not wear loose clothes during installation to avoid hooking components and causing damage.
Therefore, fasten clothes ribbons, scarves, and sleeves.
Place tools and components away from passageways to prevent collision.
Check for potential risks in the working area, for example, ungrounded power supplies, unreliable
grounding of power supplies, or wet floor.
Ambient Requirements
Temperature: 0C to 45C
Relative humidity: 10% to 90%
Cleanness: ≤ 1.4×105(particle diameter ≥ 5 μm)
Ventilation: at least 20 cm clearance around the chassis for efficient heat dissipation
Anti-interference: far away from high-power (radar or radio transmitting station), high-frequency, or
large-current devices

Confirming the Cabinet Specifications
The cabinet depth (distance between the front
and rear doors) must be large than 1200 mm.
There must be a distance of more than 180 mm
between the front mounting rails and front door of
the cabinet, and the thickness of the front door
must be smaller than 25 mm, so that more than
155 mm space is available. See Figure 1.
The load capacity of the cabinet must be large
than 400 kg.
If the N18000-X switch uses RG-PA2700I power
modules, check whether the cabinet is an IEC
cabinet, in which the PDU provides power outlets
as shown in Figure 2. In this case, use C19-C20
power cables as shown in Figure 3.

Unpacking:
An N18000-X series switch
is packed in carton, so it
can be unpacked more
quickly than an N18000
series switch.
You will find a wrench and a
screwdriver in the carton.
Use them to remove the four
L-shaped plates that fix the
chassis on the pallet. Remove
screws used to
fix the chassis

Moving the Chassis: Operation by Four
Persons Recommended
Precautions:
1. Do not hold the panels, power module
handles, or chassis handles when moving
the chassis. These parts are not
designed to bear the weight of the whole
chassis. Holding them to move the
chassis may cause damage to the parts
or even personal injury.
2. Before moving the chassis, remove the
Supervisor Engine modules, line cards,
and power modules to reduce weight of
the chassis.
Do not hold
fan handles
when moving
the chassis

Installing Shelf Brackets
An N18000-X chassis is delivered with a
pair of expandable shelf brackets.
Reserve 2 U height above the cabinet
bottom for shelf bracket installation. The
two shelf brackets are marked RIGHT
and LEFT to identify their installation
positions.
See the figure on the right for installation
positions of the shelf brackets.

There Is a Ground Bar in the Installation Environment
(Recommended)
①Remove the ground screw from the rear panel of the
chassis.
②Put the OT terminal of the ground cable delivered
with the switch on the ground screw of the chassis.
③Install the ground screw with the OT terminal to the
ground hole, fasten it with a screwdriver, and connect
the other end of the ground cable to the ground bar
of the equipment room. (Adjust the length of the
ground cable based on the distance with the ground
bar.)
There Is No Ground Bar in the Installation Environment
If the switch adoptsAC power supply, the PE cable of the
AC power supply needs to be grounded. Check whether
the PE cable of theAC power supply is properly grounded
in the power distribution room or on theAC transformer
side.

Installing Power Modules
All the chassis models have power module
slots at two sides of the chassis.
Precautions:
1. Ensure that there are no objects, such
as a PDU, near the rear mounting rails
within depth of the chassis in the cabinet
to hinder installation or removal of power
modules.
2. Each power module has a locking latch.
After connecting a power cable to a
power module, close the locking latch
to secure the power cable.
