SmartNode 1000 and 2000 Series Getting Started Guide
9 • Interface card installation
Introduction
This chapter describes how to install interface cards in a SmartNode 2000 Series device.
Safety recommendations
Follow these guidelines to ensure general safety:
•
Keep the chassis area clear and dust-free during and after installation
•
Put the removed chassis cover in a safe place
•
Keep tools away from walk areas where you or others could fall over them
•
Do not wear loose clothing that could get caught in the electronic device or chassis
•
Do not perform any action that creates a potential hazard to people or that makes equipment unsafe
•
Before opening the chassis, disconnect all cables to avoid contact with hazardous voltages
Mains Voltage: Do not open the case when the power cord is connected. Haz-
ardous voltages exist in mains-connected cables. Do not touch power supply
when the power cord is connected. Line voltages are present within the
power supply when the power cord is connected.
Hazardous network voltages are present in WAN and telephone networks
ports regardless of whether power to the device is OFF or ON. Use caution
when working near these ports to avoid electric shock. When detaching
cables, detach the end away from the SmartNode first.
Disconnect all power before servicing the SmartNode.
Electrostatic Discharge: Always follow electrostatic discharge
(ESD) prevention procedures when removing and replacing inter-
face cards. Ensure that the SmartNode chassis is electrically con-
nected to earth ground. Wear an ESD-preventive wrist strap,
ensuring that it makes good skin contact. Connect the clip to
earth ground to channel unwanted ESD voltages to ground
safely. If no ESD wrist strap is available, ground yourself by
touching the metal part of the chassis.
If you place an electronic component down on your bench, lay it
on its shielded plastic bag.
