ENVIRONMENTAL REQUIREMENTS

With Multicarrier Cabinet(s)

A fully-loaded multicarrier cabinet (five carriers) dissipates approximately 8000 BTUs per hour.

However, the typical average dissipation for a cabinet of three carriers is 5000 BTUs per hour.

With Single-Carrier Cabinet(s)

A stack of four single-carrier cabinets (fully loaded) dissipates approximately 6700 BTUs per

hour. However, the typical average dissipation for a one-carrier system is 1700 BTUs per hour.

Table AL shows the typical average and maximum system power consumption and also the sys-

tem heat dissipation for different size SCC and MCC systems.
