Interface Card Installation
8 INTERFACE CARD INSTALLATION
This chapter describes how to install interface cards on a SmartNode 2000 series device.
8.1 Safety
Recommendation
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.
Warning Mains Voltage:
Do not open the case when the power cord is connected. Hazardous
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.
Warning:
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.
Caution Electrostatic Discharge:
Always follow electrostatic discharge (ESD) prevention procedures
when removing and replacing interface cards. Ensure that the SmartNode chassis is electrically
connected 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 interface card down on your bench, lay it on its shielded plastic bag.
8.2
Installing Interface Cards
To install interface cards follow the steps described in below. Figure 8-1 depicts an example of a card
installation in SLOT 2 of a SmartNode SN2x00.
Step
Description
Step 1
Remove all cables, including mains power cord, Ethernet and telephone network
interface cables.
Step 2
Put on an ESD wrist wrap to prevent electrostatic discharge.
Step 3
Use a Phillips screwdriver to remove the cover of the SmartNode. There are a total of
nine screws on an SN2300: three on each side, two on the top at the rear (connector-side)
and one underneath at the front (LED) side. SN2400 has only six screws, two on each
side, one on the top at the rear (connector-side) and one underneath at the front (LED)
side.
Step 4
Use a Phillips screwdriver to remove the blank filler panel from the expansion slot in
which the interface card is to be installed. There are screws on the bottom of the
SmartNode; see Figure 2. Save the blank panel for future use.
