Application Equipment Module Installation guide
1
Overview
Application Module hardware is based on Meridian 1 modular packaging.
The basic unit of the modular package is the Universal Equipment Module
(UEM), which is a modular, self-contained hardware cabinet that houses a
card cage with a power supply, backplane, circuit cards, and other basic
equipment. When the UEM is equipped, it generally supports a system
function and becomes a specific type of module, such as a CPU Module or
Intelligent Peripheral Equipment (IPE) Module.
The term “Meridian 1” is used throughout this document, and refers to
Meridian 1 and “Meridian 1-ready” systems (such as Meridian SL-1 style
cabinets that have been upgraded). See Applications Module overview
guide (553-3201-110) for further information on Application Module
requirements.
In addition, the UEM houses the card cage that supports the Application
Equipment Module (AEM). When this card cage is installed, the UEM
functionally becomes an AEM. There are two versions of the AEM:
•NT7D18AA for ac-powered systems
•NT7D18AB for dc-powered systems
Application Modules, such as the Meridian Link Module, are housed in the
AEM. Each AEM can accommodate up to two Application Modules. (If
only one Application Module is installed, a blank panel covers the rest of
the AEM to channel air flow for cooling.)
An AEM with a standard Meridian 1 pedestal and top cap can be
configured as a stand-alone column. In this configuration, the AEM can
interface with:
•Meridian 1 system options 11, 21, 51, 61 or 71.

An individual AEM can be placed in a column with other Meridian 1
modules in system options 21, 51, 61 or 71. This document explains how to
install a stand-alone AEM and add an AEM to a Meridian 1 column.
AEM components
The AEM is equipped with a Module Power Distribution Unit (MPDU) on
the left (looking at the front of the AEM).
The MPDU provides two circuit breakers (see Figure 1). The top breaker
controls power to the left Application Module (the one closer to the
MPDU). The bottom breaker controls power to the second Application
Module (on the right of the AEM).

Application Equipment Module Installation guide
Stand-alone components
A stand-alone configuration consists of a pedestal, an AEM, and a top cap.
Pedestal
The pedestal houses a blower unit, an air filter, and the Power Distribution
Unit (PDU). The PDU, which distributes power to the entire column,
contains the field wiring terminal block, the main circuit breaker (or
breakers) for the column, and a slot that houses the system monitor.
The pedestal weighs 13.6 kg (30 lbs) when empty, and the dimensions are:
•812 mm (32 in.) wide
•660 mm (26 in.) deep
•254 mm (10 in.) high
There are two versions of the pedestal:
•NT8D27 for ac-powered systems
•NT7D09 for dc-powered systems
Top cap
The top cap provides airflow exits, input/output (I/O) cable entry and exit,
and overhead cable-rack mounting. Thermal sensor assemblies for the
column are attached to a perforated panel on top of the highest module in
the column, under the top cap.
The top cap weighs 3.6 kg (8 lbs) and the dimensions are:
•812 mm (32 in.) wide
•558 mm (22 in.) deep
•101 mm (4 in.) high
There are two versions of the top cap:
NT7D00AA for ac-powered systems
NT7D00BA for dc-powered systems

The recommended ambient temperature differs depending in which tier that
the AEM is placed. The following is the maximum ambient temperature for
each operating tier:
•1st tier: 35 degrees C (95 degrees F)
•2nd tier: 30 degrees C (86 degrees F)
•3rd tier: 25 degrees C (77 degrees F)

The maximum allowable ambient temperature is:
•45 degrees C (113 degrees F)
CAUTION
Equipment failure
If room temperature remains outside the

Installing a stand-alone AEM
For proper installation, perform the steps in the following procedures in the
order given.
Unpack and level the AEM column
1Remove the AEM column from the shipping pallet; follow the unpacking
instructions that come with the packaging material.
2Remove the front and rear covers from the AEM:
a. Turn the two locking latches (see Figure 3) clockwise with a
standard screwdriver.
b. Push the latches toward the center of the cover and pull the cover
towards you while lifting it away from the module.
c. Set the covers aside until the installation is complete.
WARNING
Risk of equipment damage
Module covers are not hinged; do not let go of the
cover. Lift the cover away from the module and set
it out of your work area.
3Remove the front and rear grills from the pedestal (see Figure 4). Set
the grills aside until the installation is complete.
4Inspect all equipment for physical damage; report any to your supplier.
5Adjust the feet on the pedestal to level the column (turn the leveling foot
clockwise to raise it).
Note 1: You must leave at least 12.7 mm (1/2 in.) between the floor and
the bottom of the pedestal for air flow required by the cooling unit.

Installing a stand-alone AEM 9
Application Equipment Module Installation guide
Power connections (ac)
One IG-L6-30 or L6-30 receptacle must be within 2.4 m (8 ft) of the
pedestal. Instead of using the power plug provided, you can hard-wire the
PDU to the power source. In this case, you should use #10 AWG
conductors routed through 3/4-inch conduit. Connect the leads to the L1,
L2, and GND terminations on the field wiring terminal block on the PDU.
Use a separate safety ground. The safety ground must be #6 AWG or larger
and must connect the pedestal to the service panel ground bus. Depending
on the distances between columns and the service panel, you may run
safety ground wiring independently from the AEM column to the service
panel, or you may daisy-chain the safety ground wiring between the AEM
column and the Meridian 1.
DANGER
Risk of equipment damage
Failure to follow grounding procedures can result in
an unsafe or faulty system.
Procedure 1xxx
Power connections (ac)
1Make sure the power cord is disconnected from the power source.
2Measure the resistance between the ground pin on the power plug and
a ground lug on the rear of the pedestal.
See Figure 5. The resistance should be zero ohms. If the resistance is
greater than .5 ohms, check the power cord connections.

Application Equipment Module Installation guide
Power connections (ac)
One IG-L6-30 or L6-30 receptacle must be within 2.4 m (8 ft) of the
pedestal. Instead of using the power plug provided, you can hard-wire the
PDU to the power source. In this case, you should use #10 AWG
conductors routed through 3/4-inch conduit. Connect the leads to the L1,
L2, and GND terminations on the field wiring terminal block on the PDU.
Use a separate safety ground. The safety ground must be #6 AWG or larger
and must connect the pedestal to the service panel ground bus. Depending
on the distances between columns and the service panel, you may run
safety ground wiring independently from the AEM column to the service
panel, or you may daisy-chain the safety ground wiring between the AEM
column and the Meridian 1.
DANGER
Risk of equipment damage
Failure to follow grounding procedures can result in
an unsafe or faulty system.
Procedure 1xxx
Power connections (ac)
1Make sure the power cord is disconnected from the power source.
2Measure the resistance between the ground pin on the power plug and
a ground lug on the rear of the pedestal.
See Figure 5. The resistance should be zero ohms. If the resistance is
greater than .5 ohms, check the power cord connections.

Installing a stand-alone AEM 13
Application Equipment Module Installation guide
Power connections (dc)
A stand-alone AEM column can be connected to the dc power plant used
with the Meridian 1 system.
Depending on the distances between columns and the service panel, you
may run safety ground wiring independently from the AEM column to the
service panel, or you may daisy-chain the safety ground wiring between the
AEM column and the Meridian 1.
WARNING
Risk of equipment damage
Failure to follow grounding procedures can result in
an unsafe or faulty system.
You must run all wiring (except cables to the system monitor) from the
external power equipment to the pedestal through flexible metallic conduit.
You may route a 3/4-inch conduit through four holes in the top or bottom of
the pedestal. The 3/4-inch conduit can contain a maximum of nine #10
AWG wires or five #8 AWG.
A maximum loop drop of two volts is allowed between the pedestal, or a
junction box, and the external power equipment. See Table 1 for allowable
wire sizes. See Power engineering (553-3001-152) for detailed
information on calculating wire size.
