the LAN cables.
E1
Warning: Do not work on equipment or cables during periods of
lightning activity. E2
Warning: Class I Equipment. This equipment must be earthed.
The power plug must be connected to a properly wired earth
ground socket outlet. An improperly wired socket outlet could
place hazardous voltages on accessible metal parts.
E4
Caution: Air vents must not be blocked and must have free
access to the room ambient air for cooling. E6
Warning: Operating Temperature. This product is designed for a
maximum ambient temperature of 40° degrees C. E7
Circuit Overloading: Consideration should be given to the
connection of the equipment to the supply circuit and the effect
that overloading of circuits might have on overcurrent protection
and supply wiring. Appropriate consideration of equipment
nameplate ratings should be used when addressing this
concern.
E21
Warning: Mounting of the equipment in the rack should be such
that a hazardous condition is not created due to uneven
mechanical loading.
E25
If installed in a closed or multi-unit rack assembly, the operating
ambient temperature of the rack environment may be greater
than the room ambient temperature. Therefore, consideration
should be given to installing the equipment in an environment
compatible with the manufacturer’s maximum rated ambient
temperature (Tmra).
E35
Caution: Installation of the equipment in a rack should be such
that the amount of air flow required for safe operation of the
equipment is not compromised.
