18 Gecko Frames Instruction Manual
Section 1 — Gecko 8900 Series Frames
8900TF Forced-air System
The forced-air system (Figure 2) consists of the following:
• 8900TF-V/TF-A, forced-air frame, Frame Monitor module, and one
power supply
• 8900PSX, 100 W redundant power supply (optional)
The forced-air system has a front cover that is equipped with three fans for
air circulation. The fan speed varies with the ambient frame temperature to
extend fan life and reduce noise when the frame is used in cooler configu-
rations and environments. The fan speed control voltage is generated on
the Frame Monitor module and can be disabled so that the fan runs at
maximum speed only. This frame is recommended for power requirements
greater than 30 watts or when Frame alarm reporting (via the Frame
Monitor module) is required. Refer to Frame Cooling on page 21.
Note A forced-air TF-V or TF-A frame can be converted to a networked TFN-V or
TFN-A frame with the 8900NET option.

8900TFN Networked System
The networked system consists of the following:
• 8900TFN-V/TFN-A, forced-air frame, 8900NET Network Interface
Module, and one power supply
• 8900PSX, 100 W redundant power supply (optional)
The networked system has the same features as the forced-air system
including the fan cover (Figure 2) and fault and power indicators. Also
included is the 8900NET Network Interface module allowing the frame to
communicate over an Ethernet LAN to the web browser GUI interface for
remote control of 8900 modules.
