Chapter 3 Site Preparation

Site Preparation

Temperature and humidity range: 0° to 40° C (32° to 104° F) for normal operation, 50° C for up to 72 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.

Vibration

Operating: 5 Hz to 2 kHz at .75 g peak, limited to 0.25-inch double amplitude, sine wave,

1octave/minute, two sweeps.

Non-operating: 5 Hz to 500 Hz at 1.0 g peak, limited to 0.50-inch double amplitude, sine wave,

1octave/minute, two sweeps.

Power

For AC power use, an AC power source must be available within 6 feet (1.8 m) of the MGX 8230. For systems using a DC source, Cisco does not supply the DC power cord, so the user or installer determines the wire length and the distance to the DC source. The wire should be 10 AWG (4 square millimeters).

Heat Dissipation

A fully loaded, AC-powered MGX 8230 dissipates up to 4,800 BTUs (1.4 KW hour). A DC-powered MGX 8230 dissipates up to 4,100 BTUs.

Weight

A fully loaded, DC-powered MGX 8230 can weigh up to 120 lbs (54.3 Kgs). A fully loaded AC-powered MGX 8230 can weigh up to 150 lbs (68.03 Kgs).

Caution If you move a Cisco-supplied cabinet, do not push it at its sides. Push at the front or back.

Flooring

Raised flooring with sufficient under-floor space for external cabling is best.

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 cables 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 documents for specific details.

In addition, the MGX 8230 comes with a wrist strap that you can 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.
