3. Preparing for Installation

Before installing the STS16-20RM or the STS16-20FRM Token Ring switch, read
this chapter carefully.

Safety Recommendations

Follow these guidelines to ensure general safety during and after the installation:
•
Keep the chassis area clear and dust-free during and after installation.
•
Keep tools away from walk areas where you and others could trip over them.
•
Do not perform any action that creates a potential hazard to people or makes
the equipment unsafe.

Safety with Electricity

Follow these guidelines when working on equipment powered by electricity.
Danger: Do not open the switch. Dangerous voltage inside.
Danger: To avoid shock hazard, the power cord must be connected to a properly
wired and earthed receptacle. Any equipment to which the switch will be attached
must also be connected to properly wired and earthed receptacles.
Warning: Before working on equipment that is connected to power lines, remove
jewelry (including rings, necklaces, bracelets and watches). Metal objects will heat
up when connected to power and ground and can cause serious burns or weld the
metal object to the terminals.
Warning: Do not work on the system or connect or disconnect cables during
periods of lightning activity. Read the installation instructions before you connect
the system to its power source.
To turn off the switch, you must disconnect the power cord; there is no
ON/OFF switch. Note that if the switch is connected to an external Redundant
Power Supply Unit (RPSU), the power cord must be removed from both units.
•
Locate the emergency power-off switch for the room in which you are
working. Then, if an electrical accident occurs, you can act quickly to turn off
the power.
