2.3 The Chassis
The Avaya G860 Media Gateway configuration complies with NEBS Level 3
requirements (Avaya G860 Media Gateway chassis – designed to meet - approval
pending), and conforms to CompactPCI PICMG 2.0 standards. They each contain a
10-slot card cage. All component boards have a sturdy, hot-swap cPCI 6U form factor.
Boards are inserted from the front and the back and engage the midplane on either
side inside the card cage. Slots for the boards are numbered from one to ten on the
left of the card cage in the front, for identifying board placement. The midplane
contains slot keys to match the appropriate board. This prevents insertion of a board
in a wrong location.
The Avaya G860 Media Gateway chassis configuration also houses two fan tray
units, facing the front of the chassis, one is to the left of the card cage and another is
in the upper right-hand corner of the chassis.The fan tray unit to the left of the card
cage also houses an air filter. The chassis also holds three Power Supply modules to
the right of the card cage (under the second fan tray unit).

2.3.1 Earthing Requirements
Earthing and Bonding
Connect the equipment enclosure via the provided stud to Protective earth
using No. 6 AWG copper grounding conductor from an approved earthing
electrode.
Metallic parts of network equipment installed in the outside plant shall be
grounded in accordance with Rule 99 of the most recent edition of the
National Electrical Safety Code (NESC), ANSI/IEEE C2.[36]
Safety Earth
Intrinsically, the Avaya G860 Media Gateway chassis must be safety-earthed using an
equipment-earthing conductor. Do not depend on locknut-bushings and double-
locknuts for bonding purposes. Use the earthing hardware provided with the chassis.
Earthing Electrode
The gateway must be earthed to a stable local earth earth reference. The gateway's
earth terminal should be connected thought a separate earth wire (6 recommended) to
the rack's earthing. The earth connection’s resistance must not be greater than 0.1
ohm. Verify that the rack’s earthing is properly performed.

2.3.2 Power Requirements
The Avaya G860 Media Gateway is powered from DC sources.
Table 4: Avaya G860 Media Gateway Power Requirements
Type Power Requirements Connection Provisions
DC -40.5 to -60 V DC PEMs (Power Entry Modules) with Input
terminals
2.3.2.1 Power Consumption
DC Input Power
For the Avaya G860 Media Gateway, the average power consumption for a full
complement of boards is approximately 696 watts (14.5 A at 48 VDC).
Two Power Entry Modules (PEM) are provided for DC connections on the rear of the
chassis. Power is required to be between -40.5 and -60 VDC. Each PEM unit contains
one input terminal. Each of the DC input terminals is reverse current protected. The
input terminals on each of the PEM units provide redundancy protection for the power
entry circuitry.
Recommendations for DC Power input:
When using DC power as the primary input, ensure that the power supply complies
with the safety requirements of Call Agent CAN/CSA-C22.2 No. 60950-00 and UL
60950, and EN 60950.
For High Availability, connect two separate DC power sources to avoid total power
failure if one of the DC power sources fails.
WARNING
For AC, only one PEM is to be installed in the system.
Recommendations for AC Power input:
It is recommended to connect the AC power source to a UPS to avoid total power
failure if the AC power source fails. This is mandatory for high availability (i.e., on
redundant system configurations).
Connect AC-powered systems only to earthed power outlets.
Connect the chassis to the facility’s earth, using the earthing terminal(s) provided.
2.3.2.2 Electro Magnetic Compatibility (EMC) Features
The chassis is designed to comply with known EMC/RFI standards, including FCC
Part 15, Class B; ICES-003, Class A; EN 55022, Class B; EN 300 386.
Compliance measures include:

2. Hardware Overview
Venting holes - for air intake and exhaust, sized to provide for blockage of frequencies
within the specified range
Blank panels with contact fingers - used for covering empty slots when a configuration
requires such
RFI filters - built-in to the DC power inputs, assuring that conductive interference does
not reach the Power Supply Modules, or that switching signals generated by the
Power Supply Modules do not propagate over the main feed
Air filters - integrates a honeycomb EMI shield in its assembly. The honeycomb
structure consists of "cells" that are engineered to trap and absorb EMI noise while
maintaining 95% to 99% aperture for minimal airflow impedance. A gasket installed
around the frame makes sure there is conductivity of the frame to the enclosure.
2.3.3 Midplane Keying
Each slot is equipped with a key on the midplane to match the appropriate board type
in order to prevent inserting a wrong board type into the slot.
Note: While the slot keys on the midplane are designed to prevent the insertion of
a board in an incorrect location, be sure NOT to force a board into a slot to
avoid damaging either the board or the midplane.
2.4 Cooling System
The Avaya G860 Media Gateway components are cooled by a fan tray unit (FM),
located at the left of the card cage. The fan tray unit draws cool air in through a
perforated grill on the left side of the chassis. The incoming air passes through a
removable filter (located within the fan assembly, immediately inside the perforated
grill), whose honeycombed design prevents RF interference. The air flows over the
boards, cooling them and sends the warmed air out the perforated grill on the right
side of the chassis.

20 Installation & Operation Manual
Avaya G860 Media Gateway
Refer to the figure below and for additional information, refer to 'Alarm Indicators' on
page 21.
Figure 5: FM - Fan Tray Unit
The clean air is drawn by the fans and passes through the entire set of plug-in front
and rear boards residing in the slots, cooling each one. The air exits the Avaya G860
Media Gateway via perforated vents in the chassis.
Blank panels are used to cover all unoccupied slots (as per the customer’s
configuration) on both sides of the chassis. The front blank baffled panels are
especially constructed to allow optimal air flow within the chassis.
The FM Fan Tray Module is easily removed and is hot-swappable.
The FM contains 5 fans, providing required airflow for each board in the card cage,
even if one of the fans stops working.
2.4.1 FPM - Advanced Fan Power Module
In the TPM system configuration, the Advanced Fan Power Module (FPM ) is the
power supply for the fan tray unit. It is provided in DC version according to the main
power configuration. Two FPM units are provided for redundant protection. The FPM
are not hot-swappable.
WARNING
The FPM is NOT hot-swappable, and should NEVER be removed while the
system is under power.
