CHAPTER 3: PRODUCT INSTALLATION short term, but is to be avoided if possible. Each TranScend chassis unit will draw anywhere from 0.5 Amps to 2.0 Amps (maximum) at -48 Volts, depending on the number of modules plugged, the ambient temperature, the airflow configuration etc. Please ensure that the fuse panel is rated at 3A absolute minimum for safe operation of the units.
OPERATION OF THE TRANSCEND CHASSIS Operation of the TranScend Chassis A detailed procedure for operating the TranScend chassis and various plug-in modules is described in this section. The menu operation of the plug-in modules is also described in this section. These modules include:...

. 5.1.2 Combination Button Operations The combination button operations are unique to TranScend chassis. Each combination operation is defi ned strictly for their specifi c usage as the following defi nition. Up+Down: When pressing and holding the Up+Down button simultaneously when traversing the slot menu, the front panel displays current slot number.
Menu Tree Structure The TranScend chassis LCD menu is structured into bi-level trees. The top level is system related information and the second level is plug-in related information. The top level contains the menu for second level, but each has its own menu structure.
6.2.1 Overview The High Sensitivity Quad Receiver is a TranScend plug-in meant to receive return path signals in the 5-85 MHz frequency range in RFoG networks. In these networks, the return path signal from the home ONU (Optical Network Unit) traverses an optical splitter (typically a 1x32 or a cascade of 1x4 and 1x8 splitters) in the reverse direction.

6.3.1 Overview The Return Stacker module is a TranScend plug-in meant to transmit up to four return path signals in the 5-42 MHz frequency range on one ITU wavelength. There is a node plug-in version also available for this unit, and that can be used to segment a node four ways to quadruple the upstream bandwidth from every node.
6.4.1 Overview The Return Destacker module is a TranScend plug-in that works in conjunction with the Return Stacker module (see above). It is meant to receive an optical signal and convert up to four return path signals in the 5-42 MHz frequency range and delivers them on four RF ports.
