8900TX Convection System
8900TX Convection System
The convection system consists of the following:
• 8900TX-V/TX-A, convection frame, and one power supply
• 8900PSX, redundant power supply (optional)
The convection frame has a vented front cover and filter for convective air
flow. This frame is used primarily for analog and a limited quantity of
digital modules with a total power requirement less than 30 watts. Refer to
Frame Cooling on page 21.
The convection frame is illustrated in Figure 1.

Note A convection frame can be upgraded to a forced-air or a networked frame.
This requires the use of model 8900FAN retrofit kit which provides fans and
the Fault indication window in the cover (see Figure 2 on page 14) and the
8900NET for networking capability.
