2.3 The Chassis
The Media Gateway 3500 chassis complies with NEBS Level 3 requirements, and
conforms to CompactPCI PICMG 2.0 standards. It contains 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 an wrong location.
The chassis also houses a fan tray unit to the left of the card cage and three Power Supply
modules to the right of the card cage and an extractable air filter to the left of the card
cage.

2.3.1 Earthing Requirements
Grounding and Bonding
Connect the equipment enclosure via the provided stud to Protective earth
using No. 6 AWG copper grounding conductor from an approved grounding
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 Media Gateway 3500 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.
2.3.2 Power Requirements
The Media Gateway 3500 chassis can be powered from either AC or DC sources.
