Review Safety
Guidelines
Before you perform any procedure in this document, review the safety guidelines in this section to avoid injuring yourself
or damaging the equipment. The following guidelines are for your safety and to protect equipment. Because the guidelines do
not include all hazards, be constantly alert.
Keep the work area clear, smoke and dust-free during and after installation. Do not allow dirt or debris to enter into any
laser-based components.
Do not wear loose clothing, jewelry, or other items that could get caught in the router or other associated components.
Cisco equipment operates safely when used in accordance with its specifications and product-usage instructions.
Be sure to power down a fixed configuration PDU or modular configuration power shelf before removing it from the chassis.
If potentially hazardous conditions exist, do not work alone.
Take care when connecting multiple units to the supply circuit so that wiring is not overloaded.
This equipment must be grounded. Never defeat the ground conductor or operate the equipment in the absence of a suitably installed
ground conductor. Contact the appropriate electrical inspection authority or an electrician if you are uncertain about whether
suitable grounding is available.
To prevent personal injury or damage to the chassis, never attempt to lift or tilt the chassis using the handles on modules
(such as power supplies, fans, or cards); these types of handles are not designed to support the weight of the unit.
Hazardous voltage or energy is present on the backplane when the system is operating. Use caution when servicing.
When installing or replacing the unit, the ground connection must always be made first and disconnected last.
The rack stabilizing mechanism must be in place, or the rack must be bolted to the floor before you slide the unit out for
servicing. Failure to stabilize the rack may cause the rack to tip over.
Warning
Invisible laser radiation may be emitted from disconnected fibers or connectors. Do not stare into beams or view directly
with optical instruments. Statement 1051
Cautions and Regulatory Compliance Statements for NEBS
The following are NEBS GR-1089-CORE cautions, regulatory compliance statements, and requirements:
The intra-building port(s) of the equipment or subassembly must use shielded intra-building cabling/wiring that is grounded
at both ends.
Caution
The intra-building port(s) of the equipment or subassembly is suitable for connection to intra-building or unexposed wiring
or cabling only. The intra-building port(s) of the equipment or subassembly must not be metallically connected to interfaces
which connect to the OSP or its wiring. These interfaces are designed for use as intra-building interfaces only (Type 2 or
Type 4 ports as described in GR-1089-CORE) and require isolation from the exposed OSP cabling. The addition of primary protectors
is not sufficient protection in order to connect these interfaces metallically to OSP wiring.

Review Installation
Guidelines
Before installing the
chassis, verify that these guidelines are met:
Site is properly prepared so that there is sufficient room for installation and maintenance. For specifications on the clearances
required for chassis installation, see Clearance Requirements in a Solid Door Cabinet.
Chassis is mounted
at the bottom of the rack if it is the only unit in the rack.
When mounting the
chassis in a partially filled rack, load the rack from the bottom to the top
with the heaviest component at the bottom of the rack.
If the rack is
provided with stabilizing devices, install the stabilizers before mounting or
servicing the chassis in the rack.
Airflow around the
chassis and through the vents is unrestricted.
Cabling is away
from sources of electrical noise, such as radios, power lines, and fluorescent
lighting fixtures. Make sure that the cabling is safely away from other devices
that might damage the cables.
For cable requirements for optical module connections, see the Transceivers, Connectors, and Cables section. Each port must match the wave-length specifications on the other end of the cable, and the cable must not exceed
the maximum cable length.
Clearance Requirements in a Solid Door Cabinet
The fixed-port chassis requires front-to-back airflow. Leave at least 6.0 in. (15.24 cm) front and rear clearance for air
intake/exhaust at room temperature up to 55C, and leave at least 4.0 in. (10.16 cm) front and rear clearance for air intake/exhaust
at room temperature up to 40C. Leave an additional 6.0 in. (15.24 cm)/4.0 in. (10.16 cm) rear clearance for removal and installation
of power supplies and fan modules.

Prepare Your
Location
This section illustrates how the building that houses the chassis must be properly grounded to the earth ground.
Prepare Yourself
This section
illustrates how to prepare yourself before removing the chassis from the sealed
antistatic bag. The figures show how to cuff the ESD strap around the wrist and
the ground cord that connects the cuff to the ground. ESD wrist straps are the
primary means of controlling static charge on personnel.
Prepare Rack for
Chassis Installation
Install the NCS 5500 Series chassis into a standard 19-inch, four-post Electronic Industries Alliance (EIA) cabinet or rack
with mounting rails that conform to English universal hole spacing per section 1 of the ANSI/EIA-310-D-1992 standard.
The spacing between the posts of the rack must be wide enough to accommodate the width of the chassis.

Before you move the chassis or mount the chassis into the rack, we recommend that you do the following:
Procedure
Step 1
Place the rack where you plan to install the chassis. Ensure that the rack that the chassis is being installed is grounded
to earth ground as instructed in Prepare Your Location.
Step 2
Secure the rack
to the floor.
To bolt the rack
to the floor, a floor bolt kit (also called an anchor embedment kit) is
required. For information on bolting the rack to the floor, consult a company
that specializes in floor mounting kits (such as Hilti; see Hilti.com for
details). Make sure that floor mounting bolts are accessible, especially if
annual retorquing of bolts is required.
