Smart 16e Shelf User Manual
•
Two fuses provided for separate circuits. Test before touching.
•
For continued protection against the risk of fire, replace only with the same type of
rating of fuse.
In accordance with UL 60950, the following safety guidelines must be met for installation of the
Smart 16/16e DC power supply (P/N 1200048L4 or 1202048L1):
•
The branch circuit over-current protection shall be a fuse or circuit breaker rated minimum 48 V,
maximum 15 A.
•
To be installed in a Restricted Access Location.
•
For use only with the Smart 16/16e family of products (P/N 4100023L3, 4200023L5, 4202023L1,
4202023L2, 4202023L5, and 4202023L6).
•
Two fuses provided for separate circuits. Test before touching.
•
For continued protection against the risk of fire, replace only with the same type of
rating of fuse.
The power supply can be installed in either of the two slots at the top of the Smart 16e Shelf. If only one
power supply is used, the blank power supply faceplate furnished with the rack should be installed over the
unused slot.
Only individuals familiar with installation and maintenance of the Smart 16e Shelf
should install or replace the power supplies. A shock hazard could be present if an
empty power supply slot is left uncovered.
The Smart 16e Shelf is fully operational with one power supply; however, a second supply can be added to
provide backup for the power supply subsystem. With the two-supply configuration, one of the supplies
will operate in a hot-standby mode (the corresponding output on the standby supply will automatically
provide the power required if any of the four outputs from a supply fails or begins to operate out of
specifications).
The power supplies can be "hot swapped."
Slide the power supply along the card guides of one of the top slots until it is fully seated in the connector
and the faceplate is flush with the chassis. Tighten the screws on the front of the power supply panel.
Ensure screws on faceplate are tightened securely with a screwdriver.
Each power supply has a
(+5V, -5V, +12V, and -12V) are within compliance; the
of tolerance. When operation of any one of the four voltages drops out of specification, an SNMP trap will
be sent from the controller. Failing power supplies are not user serviceable and require replacement.
