Safety messages
Safety messages are an important part of the technical documentation. The messages alert you to
hazards to personnel and equipment and provide guidance for the safe operation of your equipment.
Failure to comply with the safety messages could result in equipment damage and personal injury.
Following are the most common types of safety messages.
Warning:
Installation must be performed by qualified service personnel only. Read and follow all warning
notices and instructions marked on the product or included in the documentation.
Voltage:
This equipment relies on the building's installation for overcurrent protection. Ensure that a fuse
or circuit breaker no larger than 120 VAC/20 A or 240 VAC/16 A is used on the phase
conductors.
Caution:
This device is a Class A product. In a domestic environment, this device can cause radio
interference, in which case the user may be required to take appropriate measures.
Caution:
When mounting this device in a rack, do not stack units directly on top of one another in the
rack. Each unit must be secured to the rack with appropriate mounting brackets. Mounting
brackets are not designed to support multiple units.
Voltage:
Use only power cords that have a grounding path. Without a proper ground, a person who
touches the switch is in danger of receiving an electrical shock. Lack of a grounding path to the
switch can result in excessive emissions.

Warning:
Disconnecting the power cord is the only way to turn off power to this device. Always connect
the power cord in a location that can be reached quickly and safely in case of an emergency.
Warning:
Fiber optic equipment can emit laser or infrared light that can injure your eyes. Never look into
an optical fiber or connector port. Always assume that fiber optic cables are connected to a light
source.
Caution:
Risk of explosion if battery is replaced by an incorrect type. Dispose of used batteries according
to the instructions.
Technical specifications
The following table provides the technical specifications for the switches in this series. Ensure that
the area where you install the switch and where it operates meets these requirements.
Warning:
To avoid bodily injury from hazardous electrical shock and current, never remove the top of the
device. No user-serviceable components are inside.

Installing the switch in an equipment rack
Note:
The instructions in this section apply to all switches in Avaya Ethernet Routing Switch 4900
Series.
About this task
Install the switch in an equipment rack.
Before you begin
Tool requirements
• Phillips screwdriver to attach brackets to the switch and the switch to the rack.
Rack requirements
• Space of 2.8 inches (7.1 cm) for each switch is available in an E1A or 1EC standard 19 inch
(48.2 cm) equipment rack and T1A 23 inch (58.5 cm) equipment rack.
• Appropriate rack space is available to accommodate 1U switch height (44 mm).
• Rack is bolted to the floor and braced if necessary.

ver 02.01) 7
• Rack is grounded to the same grounding electrode used by the power service in the area. The
ground path must be permanent and must not exceed 1 Ohm of resistance from the rack to the
grounding electrode.
Note:
Avaya does not supply the bolts used to secure the switch to the rack. Ensure you obtain the
appropriate bolts to secure the switch to your specific rack before you begin.
Procedure
1. Ensure power is disconnected from the switch.
2. Attach a bracket to each side of the switch with the included screws.
You have different options for front and rear mounting positions. Attach the brackets in the
best position for your specific equipment rack.
