The EMS100G32-R2 switch is suitable for installation as part of a common bond network (CBN).
You can install the switch in:
Network telecommunication facilities
Data centers
Other locations where the National Electric Code (NEC) applies
NOTE:
Install the switch into a rack or cabinet before installing any additional components such as cables or optics.
SITE SELECTION
Install the switch equipment in restricted access areas.
A restricted access area is one in which service personnel can only gain access using a special tool, lock, key or other
means of security. The authority responsible for the location controls access to the restricted area.
Ensure that the area where you install your switch meets the following safety requirements:
Install the switch near an adequate power source. Connect the switch to the appropriate branch circuit protection
according to your local e lectrical codes.
The switch’s environmental temperature range is from 32 to 113°F (0 to 45°C).
The relative humidity is from 5 to 90 percent noncondensing.
Install the switch in a dry, clean, well-ventilated, and temperature-controlled room, away from heat sources such as
hot air vents or direct sunlight.
Install the switch away from sources of severe electromagnetic noise.
Install the switch inside of the restricted access area, positioned in a rack or cabinet, or on a desktop with adequate
space in the front, back, and sides for proper ventilation and access.
Install the switch in Information Technology Rooms in accordance with Article 645 of the National Electrical Code
and NFPA 75.
For more information about switch storage and environmental temperatures, see “Specifications.”
CABINET PLACEMENT
Install the switch only in indoor cabinets designed for use in a controlled environment.
Do not install the switch in outside cabinets. For cabinet placement requirements, see “Site selection.”

SITE PREPARATIONS
RACK MOUNTING
When you prepare your equipment rack, ensure that the rack is grounded.
Ground the equipment rack to the same ground point the power service in your area uses. The ground path must be
permanent.
SWITCH GROUND
Black Box recommends that you ground your switch. Use the switch in a common bond network (CBN). Connect the
grounding cables as described in Switch installation.
NOTE:
For an AC-powered switch, although the third conductor of the AC power cable provides a ground path, Black Box
recommends grounding your switch with a dedicated ground wire. You can order an AC ground lug separately.
NOTE:
For a DC-powered switch, the only way to safely ground your switch is to attach a dedicated ground wire. The ground
lug kit ships in a plastic bag placed with the other accessories inside the shipping box. The ground lug bracket screws
ship attached to the switch. Before you install the DC switch in the dual-tray, attach the ground lug and bracket to
the switch using the included screws and then attach the DC ground wire to the ground lug. The DC-powered switch
ships with the DC ground lug, bracket, and screws.
FANS AND AIRFLOW
The switch fans support two airflow options: normal and reverse.
FAN COMBINATIONS
Fan installation is done as part of the factory install based on stock keeping unit (SKU) type. The switch has SKUs that
support the following configurations:
AC or DC PSU with fan airflow from the I/O to the PSU—the red indicator is the normal airflow direction
AC or DC PSU with fan airflow from the PSU to the I/O—the blue indicator is the reverse airflow direction
Order the fans suitable to support your site’s ventilation. Use a single type of airflow fan in your switch. Do not mix
reverse and normal airflows in a single switch.
For proper ventilation, position the switch in an equipment rack or cabinet with a minimum of 5 inches (12.7 cm) of
clearance around the exhaust vents. When you install two EMS100G32-R2 switches near each other, to permit proper
airflow, position the two switches at least 5 inches (12.7 cm) apart. The fan speed varies based on internal temperature
monitoring. The EMS100G32-R2 switch never intentionally turns off the fans.
For more information, see “Fans.”

POWER
To connect the switch to the applicable power source, use the appropriate power cord. An AC power cord is included
with each PSU.
When installing AC or DC switches, follow the requirements of the National Electrical Code, ANSI/NFPA 70, where
applicable.
The switch is powered-up when you connect the power cord between the switch and the power source. For more
information, see Power supplies.
CAUTION:
FAlways disconnect the power cable before you service the power supply slots. The switch has multiple power cords.
Before servicing, ensure all power cords are disconnected.
CAUTION:
On an AC switch, use the power supply cord as the main disconnect device. Ensure that the socketoutlet is located
and installed near the equipment and is easily accessible.
NOTE:
Module power is software controlled. You do not see module LEDs when the switch powers up in ONIE.
STORING COMPONENTS
If you do not install your EMS100G32-R2 switch and components immediately, properly store the switch and all
components using these guidelines:
Storage location temperature must remain constant. The storage range is from -40 to +158°F (-40 to +70°C).
Store on a dry surface or floor, away from direct sunlight, heat, and air conditioning ducts.
Store in a dust-free environment.

recommends grounding your switch with a dedicated ground wire. You can order an AC ground lug separately.
NOTE:
For a DC-powered switch, the only way to safely ground your switch is to attach a dedicated ground wire. The ground
lug kit ships in a plastic bag placed with the other accessories inside the shipping box. The ground lug bracket screws
ship attached to the switch. Before you install the DC switch in the dual-tray, attach the ground lug and bracket to
the switch using the included screws and then attach the DC ground wire to the ground lug.
The ground cable is not included. The grounding lugs must be a UL-recognized, crimp-type lug.
CAUTION : Grounding conductors must be made of copper. Do not use aluminum conductors.
NOTE:
Coat the one-hole lug with an anti-oxidant compound before crimping. Also, bring any unplated mating surfaces
to a shiny finish and coat with an anti-oxidant before mating. Plated mating surfaces must be clean and free from
contamination.

NOTE:
The rack installation ears are not suitable for grounding.
To connect the ground cable to the switch:
Cut your user-supplied ground cable to the desired length.
The cable length must facilitate proper operation of the fault interrupt circuits. Use the shortest cable route
allowable.
Crimp the ground cable inside the pre-installed ground lug.
Attach the other end of the ground cable to a suitable ground point such as the rack or cabinet.
The rack installation ears are not a suitable grounding point.
RACK OR CABINET HARDWARE INSTALLATION
You may either place the switch on a rack shelf or mount the switch directly into a 19” wide, EIA-310- E-compliant
rack. Rack mounting for the EMS100G32-R2 switch includes four-post, two-post, round threaded holes, or square
holes. The ReadyRails system is provided for 1U front-rack and two-post installations.
The ReadyRails system includes separately packaged rail assemblies.
WARNING : This document is a condensed reference. Read the safety instructions in your Safety, Environmental,
and Regulatory information booklet before you begin.
NOTE:
The illustrations in this document are not intended to represent a specific switch.
NOTE:
Do not the use the mounted ReadyRails as a shelf or a workplace.
RACK MOUNT SAFETY CONSIDERATIONS
Rack loading—Overloading or uneven loading of racks may result in shelf or rack failure, possibly damaging the
equipment and causing personal injury. Stabilize racks in a permanent location before loading begins. Mount the
components starting at the bottom of the rack, then work to the top. Do not exceed your rack’s load rating.
Power considerations—Connect only to the power source specified on the unit. When you install multiple
electrical components in a rack, ensure that the total component power ratings do not exceed the circuit
capabilities. Overloaded power sources and extension cords present fire and shock hazards.
Elevated ambient temperature—If installed in a closed rack assembly, the operating temperature of the rack
environment may be greater than the room ambient temperature. Use care not to exceed the 113°F (45°C)
maximum ambient temperature of the switch.
Reduced air flow—Install the equipment in the rack so that the amount of airflow required for safe operation of the
equipment is not compromised.
Reliable earthing—Maintain reliable earthing of rack-mounted equipment. Pay particular attention to the supply
connections other than the direct connections to the branch circuit, for example, use of power strips.
Do not mount the equipment with the back panel facing downward.

ONE U READYRAILS INSTALLATION
You can install the ReadyRails system using the 1U tool-less square-hole method or one of three possible 1U threaded
round-hole methods. The tooled installation methods include two-post flush mount, two-post center mount, or four-
post threaded mount.
To begin installation, separate each rail assembly by sliding the inside rail out of the outside rail.
