APX 1000™ Getting Started Guide
Installing an APX 1000 Chassis
Handling APX 1000 components
installed in a closed or multirack assembly, because the operating ambient temperature of
the rack environment might be greater than room ambient temperatures.
•
In enclosed racks, make sure that openings exist in the floor underneath each cabinet to
allow cool air into the cabinet.
•
Exhaust fans at the top of the cabinet are recommended but not required. At a minimum,
ensure that the cabinets are ventilated at the top.
•
The unit’s fans draw air in from the front and exhausts it in the rear to sufficiently cool
each unit. Consequently, air gaps at the top, bottom, or sides of APX 1000 units are not
required.
Handling APX 1000 components
To prevent damage to components from electrostatic discharge, always follow the proper
guidelines for equipment handling and storage. Modules, slot cards, and semiconductor
devices in general can be easily and permanently damaged due to electrostatic discharge
during installation or removal. A person walking across a floor can generate electrostatic
voltages in excess of 5000V.
Although you might not notice a discharge of less than 3500V, discharges below 100V can
damage semiconductor components. Because these discharges have very little current, they are
harmless to people.
Use a wrist strap
To reduce the static potential on your body by proper grounding, wear an approved antistatic
wrist strap (Figure 3-1) when installing, removing, or handling modules, or while handling any
Lucent device containing semiconductor components.
!
Caution:
Correct use of an approved antistatic wrist strap is the only reliable way to prevent
damage to components by electrostatic discharge from your body
