Selecting a Site
Before you install the switch, review the following considerations about its
location.
■For compatibility with Network Equipment Building System (NEBS), the
switch must be located in a network telecommunications facility.
■The Rapier 48w switch requires an ambient temperature from 0ºC to 50ºC
(32ºF to 122ºF).
■There should be adequate front-to-back airflow around the switch and its
vents.
■The site should be dust-free and without moisture.
■Humidity can be from 5% to 80% non-condensing.
■You need a reliable and earthed (grounded) power supply source, preferably
dedicated and filtered.
■Switch ports suitable for connection to intra-building or non-exposed
cabling are required.
■Cabling must not be exposed to sources of electrical noise, such as radio
transmitters, broadband amplifiers, power lines, electric motors, and
fluorescent fixtures.
■Related network devices can be connected to the switch but cannot exceed
maximum cable lengths specified in the Hardware Reference.
■Ensure easy access to the switch’s power and cable connections.
■You may need to remove cabinet doors to accommodate cords and cables.
■When rack mounted, the switch must be located evenly to prevent uneven
mechanical loading of the rack.

Installing the Switch
Ports on the switch are suitable only for connections within buildings (intra-
building) and with cables unexposed to the outside.
You can install the switch on a level surface, such as a desktop or bench, in a
standard 19-inch rack, or in a 23-inch rack.
Before you begin
■Read the safety information.
For your well-being and that of the equipment, read the safety information in
this document. You can also download this document from
www.alliedtelesis.com/support/software.
■Verify the package contents if you have not already done so.
See “Package Contents” on page 4. If any items are damaged or missing,
contact your authorised distributor or reseller.
■Gather necessary tools and equipment:
• a Phillips #2 screwdriver for fitting the rack-mount brackets
• four rack-mount screws and cage nuts (if required)
• a flat screwdriver for the captive screws on the fan units and the DC
power connection
• a suitable spanner for tightening the nuts on the chassis grounding stud
• an appropriate DC power source, DC supply cable, ring connectors,
wire strippers, and a PANDUIT Uni-Die® dieless crimping toolset
■Prepare the cabinet in a suitable location
Follow guidelines described in “Selecting a Site” on page 5 to choose an
appropriate location and modify the rack as necessary.
You can install the switch in a 19-inch rack, a 23-inch rack, or on a flat bench.
■If you have an optional Network Service Module (NSM), or Port Interface
Cards (PICs), install them in the switch first.
For details, refer to the Network Service Module Installation and Safety Guide and
the Port Interface Card Installation and Safety Guide. These guides are shipped
with each NSM or PIC. You can also download them from
www.alliedtelesis.com/support/software.

Preparation for NEBS
To ensure rack-mounted installations are earthed for compatibility with
Network Equipment Building System (NEBS), all bare conductors must be
coated with an appropriate antioxidant compound before making crimp
connections.
Warning All versions of this equipment must be earthed.
Rack-mount the switch
1. Ensure the rack has sufficient space for the switch and its cables. For the
switch’s requirements, see “Selecting a Site” on page 5.
2. Install cage nuts, if required, so they are ready for the rack-mount screws in
the following steps. The Rapier 48w can be front, center, or rear mounted.
3. Unpack the switch.
4. Screw one bracket to each side of the switch using the M4 screws provided.
5. Mount the switch into the rack, and tighten the 4 rack-mount screws.

Install the air filters
For compatibility with Network Equipment Building System (NEBS), this switch
requires a filtered air supply. The switch is shipped with air filters which must be
installed in each of the fan units.
To install an air filter:
1. Using a flat screwdriver, undo the captive screws on the front of the fan
unit.
2. Slide the fan unit out of its cage. The internal power connection is quite
solid, so pull firmly on the captive screws.
3. Insert the air filter into the narrow slot between the front grill of the fan
unit and the fan. Position the air filter with the plastic frame towards the fan
and the pull tab to the top. The air filter should fit snugly.
4. Slide the fan unit back into its cage, making sure that the air filter and the
pull tab are clear of any contact points.
5. Press the fan unit firmly into place and tighten the captive screws on the
front of the fan unit.

Applying Power to the Switch
The specific power supply requirements for the Rapier 48w are clearly displayed
on the rear of the switch. If the supply is outside the accepted range for the
switch, the switch may not operate or damage to the switch may result.
Read “Safety” on page 20 of this document before connecting a DC power
supply.
Warning Only trained and qualified personnel should connect a DC power
supply.
For centralised DC power connection, the switch should be installed in
restricted access areas only (such as dedicated equipment rooms or
equipment closets) in accordance with Articles 110-16, 110-17, and 110-18 of
the National Electrical Code, ANSI/NFPA 70.
Damage to equipment may result if power is connected improperly.
Before working on equipment that is connected to power, remove jewellery
including rings, necklaces, and watches. Metal objects will heat up when
connected between power and ground, and can cause serious burns or weld the
metal object to the terminals.
DC supply cable and power supply
Supply cable specifications:
■two-core cable is required
■minimum core size: 2.1mm2(14 AWG)
■minimum cable rating: 600 V, 90 degrees C
Power supply specifications:
■48 VDC (40 to 60 VDC is acceptable)
■supports either positive grounded or negative grounded operation
■a 15Amp certified/listed circuit breaker is required for circuit protection

Connect the switch to ground
The protective earth connection should be connected before proceeding with
the following power connections. The primary ground for the equipment is a
two stud grounding block (bearing the grounding symbol) located on the left
rear of the chassis, adjacent to the DC power connector.
To connect the switch to ground:
1. Using a 10AWG (5mm2cross sectional area) grounding cable (green with
yellow stripe), connect the chassis grounding stud to the office primary
ground using the two nuts with integral lock washers supplied. Tighten the
nuts with an appropriate spanner.
2. Strip an 18mm (0.75 inch) length of insulation from the grounding cable and
connect this to the grounding stud crimp terminal, using PANDUIT Uni-
Die® dieless crimping toolset. Ensure that no stranded wires protrude
from the terminal. The torque value for the chassis grounding studs is 2.57
Nm (22.8 lbf in).
Connect the DC supplies
To provide power supply resiliency, the Rapier 48w switch can receive its DC
power from either of two separate sources. Each power source should supply
48V DC (40 to 60VDC) to the switch. When the switch is powered by
centralized DC power, use UL Listed Type TC tray cables to connect the
equipment to the power sources. Each tray cable should have two conductors in
the range #14 to #12 AWG (2.0 to 2.5mm2cross sectional area), such as Belden
No. 3081A.
Each DC branch circuit should connect to the Rapier switch via a 15A
(maximum) circuit breaker or fuse that meets the requirements for branch
circuit protection. The DC supply should be fed via a circuit breaker or switch
capable of disconnecting power during servicing. The tray cable should be a UL
Listed Type TC tray cable with two conductors in the range #14 to #12 AWG
(2.0 to 2.5mm2cross sectional area), such as Belden No. 3081A.
To connect the DC supply:
1. Ensure that the DC power source is powered off during installation.
2. Strip 12mm (0.5inches) of jacket material off the tray cable and strip 7mm
(0.27inches) of insulation off each individual wire.
