Rack Installation
Guidelines for Mounting Equipment in a Rack
When installing equipment in a rack, give careful consideration to the following factors:
• The operating ambient temperature of rack-mounted equipment must not exceed the
maximum rated ambient temperature, which is indicated in this installation guide. (See
“Operating Conditions” on page 41 .)
• The air flow clearances specified in this installation guide must be maintained within the rack.
(See
“Operating Conditions” on page 41 .)
• The AC supply circuit for rack-mounted equipment must be capable of supplying the total
current specified on all the labels of the rack-mounted equipment.
• All AC power supply connections must be properly earthed. To ensure the integrity of the
earth connection, special attention must be given to connections that are not directly
connected to the branch circuit (for example, power strips).
• The rack-mounting hardware has been carefully selected to properly support the equipment.
Any alternate rack-mounting hardware must provide equal or superior support.
• Plan the device installation starting from the bottom of the rack cabinet. Install the heaviest
device in the bottom of the rack cabinet.
For information on environmental requirements, see “Operating Conditions” on page 41 .
Switch LEDs
The switch incorporates three sets of Light-Emitting Diodes (LEDs) to indicate Ethernet, switch, and
port status:
1. Ethernet LEDs – two separate LEDs indicating the network connection status.
2. System LEDs – three separate LEDs indicating the switch’s status.
3. Port LED – one multi-colored LED per port indicating the port’s status.
