Inspecting Your Shipment When you receive the equipment, inspect it for signs of damage. If the equipment has been damaged in transit, immediately report the extent of damage to the transportation company and to PairGain. Your shipment should consist of: •... - Page 11 Section 150-219-100-02 You must observe these constraints for reliable service under worst- case conditions. Consult PairGain when using the enclosures in environments that are more hostile than those allowed by the constraints or when using unlisted enclosures. Deployment rules for determining the the best location for the enclosures are provided in "Locating Doubler Unit Enclosures"...
- Page 12 Section 150-219-100-02 December 22, 1997 For example, if the solar load is removed from the SPC 7430-8 T1 slot enclosure, whose capacity is two doubler units with solar load, capacity is increased to three doubler units. But this would necessitate placing two doublers side by side, with no empty slot between them.

December 22, 1997 Section 150-219-100-02 Figure 4. HCT-239 Insertion Tool Locating Doubler Unit Enclosures The physical location of the doubler units is determined by the following three deployment rules: Place the enclosures at the electrical limits, 35 dB, of each span. This would place the first doubler at the 35 dB location and the second at 70 dB. -
