hours. Recommend range of 20° to 30°C. Up to 85% relative humidity, non-condensing .
•Shock
–
Operating: 10 g shock, three pulses in the positive and negative directions, all axes, 1/2 sine
wave, 11 ms duration.
–
Non-operating: 20 g shock, three pulses in the positive and negative directions, all axes,
1/2 sine wave, 11 ms duration.
•Vibra tion
–
Operating: 5 Hz to 2 kHz at .75 g peak, limited to 0.25-inch double amplitude, sine wave,
1 octave/minute, two sweeps.
–
Non-operating: 5 Hz to 500 Hz at 1.0 g peak, limited to 0.50-inch double amplitude, s ine wave,
1 octave/minute, two sweeps.
•Power
For AC power use, an AC power source must be availabl e w i th in 6 f eet ( 1. 8 m) of t he M G X 8 23 0.
For systems using a DC source, Cisco does not supply the DC power cord, so the user or installer
determines the wire length and t he di sta nce to the DC sour ce . T he wir e sh oul d be 1 0 AWG (4 square
millimeters).
•Heat Dissipation
A fully loaded, AC-powe red MGX 8230 diss ipates up to 4,800 BT Us (1.4 KW ho ur). ADC-powered
MGX 8230 dissipates up to 4,100 BTUs.
•Weight
A fully loaded, DC-powered MGX 8 230 ca n weigh up to 120 lbs (54.3 K g s ) . A f u lly l oa ded
AC-powered MGX 8230 can weigh up to 150 lbs (68.03 Kgs).

•Flooring
Raised flooring with sufficie nt u nd er- f lo or s p ac e for external cabling is b est .
•Mounting
The location of the IGX or BPX switch, which has a co-located MGX 8230 IP + ATM Edge
Concentrator, should accommodate the routing of the data cab les and the termination of the
telephone company’s or common carrier’s circuits.
•Electrostatic Discharge
The building should provide adequate grounding to prevent damage from electrostatic discharge.
See the sections “Bonding and Grounding” in the IGX or BPX installation d ocuments for specific
details.
In addition, the MGX 8230 comes wi th a w ris t str ap th at yo u c an connect to the rear of the chassis
near the ground lug or to a convenient point on the front of the chassis. You should put on a wrist
strap before handling any cards.
