Figure3.1-1 Assembly Diagram of Portable Frame
Insertion of M5 Nut Cramp 
In order to fix the master unit cabinet, master unit cabinet supports and
tail fiber tray, M5 nut cramps should be pre-inserted onto the two columns of
portable frame. Figure 3.1- 2 shows the inserting points-small black square
holes, symmetrical on each column. At the back of the columns (i.e. the side
with ground copper slip or many round holes), 2 nut cramps should also be
inserted into hole 15 and 16 separately since master unit cabinet support should
be fixed at both sides of columns. No nut cramps need to be inserted into other
holes at the rear sides of the columns. Nut cramps are inserted from inside to
outside as shown in figure 3.1- 3. After nut cramps are inserted, fix the two
master unit supports onto the two columns with M5 nuts at hole 15 and 16. Nuts
should be tightened at both sides of the columns.
