SUBMISSIONS

Airflow path design: – REQUIRED FOR ALL SUBMISSIONS

Are equipment air flow path(s) only front (intake) to rear (exhaust) (FX – RX) ? Yes _____

No _______

If No:

• Specify Path(s) ________________ _________________ ________________

• Attach a diagram depicting each of the path(s) & Specify direction of each of the flow(s)

Notes:

1) At no time shall Maximum Heat Dissipation be larger than List 1 Power Drain

2) Where possible, heat dissipation measurements should be measured rather than calculated.

• If the heat dissipation measurement is measured, follow the entry with a hyphen and the letter “M” for

measured

• If the heat dissipation measurement is calculated, follow the entry with a hyphen and the letter “C” for

calculated

• Examples: Measured = 4,000 – M or Calculated = 3,500 – C

• The “M” or “C” shall be included for each heat dissipation measurement entry

3) A: Maximum possible is the total number of units that may be deployed in a system by engineering design

4) B: AT&T design is the total number of units that AT&T will typically deploys in a system.

• If the typical AT&T units deployed are unavailable, indicate the maximum number followed by a hyphen

and the letter “U” for unknown. (e.g. 4-U)
