Rapier 48w Switch
Switches Covered By This Guide
This document includes information on the following switches:
■ Rapier 48w (DC model)
■ Rapier 48w-B (AC and DC models)
The Rapier 48w and 48w-B switches have the same features, however the
physical connection between the switch and NSMs is different. The compatible
NSMs for each model are:
■ Rapier 48w: AT-AR040, AT-AR048
■ Rapier 48w-B: AT-AR040-B, AT-AR048-B
In this guide, the product name Rapier 48w refers to both the Rapier 48w and
the Rapier 48w-B models, except where an explicit reference is made.
You can download updates to this document from
www.alliedtelesis.com/support/software.
NEBS Compliance
The Rapier 48w DC models meet Network Equipment Building System (NEBS)
compliance under the following conditions:
■ The switch is located in a network telecommunications facility.
■ When rack-mounted, all bare conductors are coated with an appropriate
antioxidant compound before making crimp connections.
■ The supplied air filters are installed in both fan units.
For information about NEBS requirements when connecting cables to the
switch, see
“Connecting Data Cables to the Switch” on page 14.
The Rapier 48w AC model has not been tested for NEBS requirements.

Rapier 48w Switch
Selecting a Site
Before you install the switch, review the following considerations about its
location.
■ The Rapier 48w switch requires an ambient temperature from 0º C to 50ºC
(32º F to 122º F).
■ 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.
■ The switch ports are suitable for connection to intra-building or non-
exposed cabling only (NEBS requirement)
■ 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.
■ Rapier 48w DC models are NEBS compatible only when the switch is
located in a network telecommunications facility.

Installation and Safety Guide
Installing the Switch
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.
The ports on the switch must not be metallically connected to interfaces that
connect to Outside Plant or its wiring (NEBS requirement).
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 5. If any items are damaged or missing,
contact your authorised distributor or reseller.
■ Gather necessary tools and equipment.
For a Rapier 48w AC switch, you will need:
• a Phillips #2 screwdriver for fitting the rack-mount brackets
• four rack-mount screws and cage nuts (if required)
For a Rapier 48w DC switch, you will need:
• 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 6 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.

Installation and Safety Guide
Install the air filters (NEBS installation only)
Rapier 48w DC switches are shipped with air filters that you must install in each
of the fan units for Network Equipment Building System (NEBS) compliance.
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.
Warning All versions of this equipment must be earthed.
Rapier 48w AC switch
Follow these instructions when powering the AC switch variant.
1. Plug the provided AC power cord into the power inlet.
2. Connect the power cord to the main power source.
3. Check that the PSU LED on the front panel of the switch is lit green. If the
LED does not light, refer to the Hardware Reference for troubleshooting
information.

Rapier 48w DC switch
Follow these instructions when connecting the DC switch variant. Read “Safety”
on page 23 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.
NEBS preparation when rack-mounted
To ensure rack-mounted installations are earthed for compatibility with NEBS,
all bare conductors must be coated with an appropriate antioxidant compound
before making crimp connections.
DC supply cable and power supply
Supply cable specifications:
■ two-core cable is required
■ minimum core size: 2.1mm
■ 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 15 Amp 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 10 AWG (5mm2 cross sectional area) grounding cable (green with
2. Strip an 18 mm (0.75 inch) length of insulation from the grounding cable and
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
V DC (40 to 60 VDC) 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 2.5
