Installation
Preinstallation Considerations
Consider the following before performing installation of the Hotwire 8620
GranDSLAM chassis:
n Installation Site
Your installation site should be well ventilated, clean, and free of
environmental extremes. If you are installing the Hotwire 8620 GranDSLAM
chassis in a central office (CO) rack, make sure there is a clearance of 2 to 3
feet at the front of the rack to allow access for the installation of the chassis,
circuit cards, and cables. If you intend to use the rear cable connectors, allow
for sufficient clearance at the rear of the chassis for cabling.
n Power
The AC power version requires a power source of 100–240 VAC (nominal) at
50–60 Hz; maximum current draw is 4 A at 120 VAC.
The DC power version requires a 48 VDC power source (48 VDC, nominal;
maximum current draw is 5 A). The size of power source wires must be
between 14 AWG and 18 AWG, and can be either solid or stranded. However,
14 AWG stranded wire is recommended.
n Grounding
A ground lug is located at the lower center of the cover at the rear. It accepts
14 AWG wire.
A noninsulated banana jack is located on the left front of the unit to provide a
ground for an ESD wrist strap.
