About this guide 3

NEBS compliance
For your system to be network equipment building system (NEBS) compliant, you must
follow the instructions detailed in this chapter.
To be NEBs compliant, orient your system in the rack so that the air inlet is from the front
aisle and the air exhaust is from the rear aisle.
Important information
WARNING: The quad form-factor pluggable (QSFP), BaseT, console, Ethernet
management, and universal serial bus (USB) ports are suitable for connection to
intra-building or unexposed wiring or cabling only. You MUST NOT metallically
connect the ports to interfaces that connect to the out side plant (OSP) or its
wiring. Use these interfaces as intra-building interfaces only—Type 2 or Type 4 ports
as described in GR-1089-CORE, Issue 6. Also, they require isolation from the
exposed OSP cabling. Adding primary protectors is not sucient protection to
connect these interfaces metallically to OSP wiring.
WARNING: If you install and connect the S4048T-ON to a commercial AC power
source, you must connect the system to an external special protection device
(SPD).
WARNING: Use shielded intra-building cabling that is grounded at both ends for the
1/10GbE BaseT intra-building ports.
To be NEBS compliant, follow these regulations:
• Locate your system in a restricted-access area were only trained personnel are allowed
access.
• Install and connect your system to the common bonding network (CBN).
• You can also install and connect your system to the central oce.
• Connect the battery returns of your system as DC-I.
2
4 NEBS compliance

• Ground your system using a copper ground conductor.
• Clean and coat all bare grounding connection points on your system with an anti-oxidant
solution before making connections.
• Bring all unplated surfaces on your system to a bright nish and treat them with an anti-
oxidant solution before making connections.
• Remove any non-conductive surfaces on your system from the threads and connection
points to ensure electrical continuity.
• Use the two-hole, Listed, compression-type lug with an AWG 14 gauge wire that uses 4-
in/lb to secure your system to the frame.
NOTE: The S4048T-ON can operate at -40.5 to -60 VDC at a maximum current level
of 24A or at 100–240 VAC at a maximum current level of 7.1A.
NOTE: The S4048T-ON is Earthquake Z4-compliant when you attach the
ReadyRails to the frame using threaded hardware. Do not use the tool-less or two-
post installation methods.

Hardware installation
This information describes installation of the S4048T-ON system. Dell recommends
completing the installation procedures in the order presented here.
Topics:
• Operation and safety considerations
• Ground and bracket installation
• ReadyRails installation
• System installation
• Ground wire installation
• AC or DC power supply installation
• Installing a Fan Module
• Installing the SFP+ and QSFP+ Optics
• Supply Power and Power Up the System
• After Installing the S4048T-ON
Operation and safety considerations
Before installing the switch, review these operation and safety guidelines.
Review these guidelines for switch installation:
• You have enough clearance to the front of the switch so you can read the light emitting
diodes (LEDs).
• The AC power cord reaches from the power outlet to the power supply unit (PSU) side
connector.
• The switch is rack-mounted before you power it up.
• Cabling is away from sources of electrical noise, such as radios, power lines, and
uorescent lighting. Ensure that the cabling is safely away from other devices that might
damage the cables. If needed, allow one rack unit (RU) space between devices to
provide room for cabling.

6 Hardware installation

•Airow around the switch and through the vents is unrestricted.
• Temperature around the unit does not exceed 113°F (45°C). If the switch is in a closed
or multi-rack assembly, the temperature might be higher than normal room temperature.
• Humidity around the switch does not exceed 95 percent.
• Altitude at the installation site is below 10,000 feet.
• The switch is installed in an environment as free as possible from dust and foreign
conductive material; for example, metal akes from construction activities. Cooling
mechanisms, such as fans and blowers in the switch, can draw dust and other particles
causing contaminant buildup inside the chassis, which can result in system malfunction.
Review these guidelines for rack mounting:
• Rack mounting—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 loading—Overloading or uneven loading of racks may result in shelf or rack failure
that can cause damage to the equipment and possible 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 load rating.
• Power considerations—Connect only to the power source specied 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 re and shock hazards.
• Elevated ambient temperature—If you install the equipment in a closed rack assembly,
the operating temperature of the rack environment may be greater than the room
ambient temperature. The acceptable ambient temperature ranges are listed in Technical
Specications under Environmental Parameters.
• Reduced air ow—Install the equipment in the rack so that you do not compromise the
amount of airow required for safe operation of the switch. For proper ventilation,
position the chassis in an equipment rack or cabinet with a minimum of 5 inches (12.7
cm) of clearance around exhaust vents.
• Reverse air ow—To ensure cool air intake and to avoid hot air blow out from the I/O
side, ensure that you have the necessary clearance.
• 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 PSU side facing in a downward position.
NOTE: Always handle the system and its components with care. Avoid dropping the
chassis or their eld replaceable units.
Hardware installation 7

CAUTION: Always wear an electrostatic discharge (ESD)-preventive wrist or heel
ground strap when handling a system and its components. As with all electrical
devices of this type, take all necessary safety precautions to prevent injury when
installing this system. ESD damage can occur if components are mishandled.
CAUTION: Only trained and qualied personnel should install this equipment. Read
this guide before installing and powering up the system.
WARNING: This section is a condensed reference. Read the safety instructions in
your Safety, Environmental, and Regulatory information booklet before you begin.

AC or DC power supply installation
The S4048T-ON supports two hot-swappable power supplies with integrated fans that
provide cooling for the chassis. The system supports AC power supplies with two air-ow
directions—I/O to Utility and Utility to I/O.
1 Remove the PSU from the electrostatic bag.
2 Remove the PSU slot cover from the switch.
3 Use the grab handle to slide the PSU into the switch PSU slot.
The PSU slot is keyed such that the PSU can only be fully inserted in one orientation.
The PSU slides into the slot smoothly. Do not force the PSU into a slot as this action
may damage the PSU or the chassis.
Figure 11. AC or DC PSU installation
4 Repeat steps 1 through 3 for the second PSU.
WARNING: The PSU side includes two slots, PSU1 and PSU2. Although the switch
can run on one PSU, Dell highly recommends using two PSUs for full redundancy
and more cooling. To avoid overheating when the switch is running with only a single
PSU, use PSU1, on the left when facing the PSU side. Cover the second PSU,
PSU2, with a blank plate.
