2.2 Standard Nomenclature
The standard nomenclature for AMETEK carrier protection equipment is as follows:
Cabinet – contains fixed-racks, swing-racks, or open racks
Rack – contains one or more chassis (e.g., the UPLC-II™)
Chassis – contains several printed circuit boards, called modules (e.g., Power Supply or Transceiver)
Module/Card/Board – contains a number of functional circuits (e.g., Oscillator or Microprocessor)
Circuit – a complete function on a printed circuit board
2.3 UPLC-II™ Chassis
The Front Panel requires a screwdriver to open. It is shown in Figure 2–1. See Figure 2–2 for the back-
plane. The UPLC-II™ chassis specifications (see Figure 2–3) include standard dimensions of:
Height – 5.25” (133.35 mm), requiring 3 rack units, each measuring 1.75” (44.45 mm)
Width – 19.00” (482.6 mm) Depth – 13.50” (342.9 mm)
The chassis includes a two-piece metal cover plate on back. The top half of the cover plate is easily remov-
able with 4 captivated screws fastening it. Loosen screws, pull bottom out then down to remove.
Each chassis is notched for mounting in a standard 19” rack and has adjustable mounting brackets on the
sides. It may be flush-mounted against another chassis on top & bottom.
2.4 UPLC-II™ Modules
The basic UPLC-II™ has 7 standard printed circuits boards in a 3RU 19 inch chassis. There are 4 addi-
tional boards that may be supplied, based upon the catalog number purchased. These modules are:
The block diagram, illustrating how these are all interconnected is on Page 2–22.
