5.3 Power Supply
Power is supplied to the ASMi-31/R card from the ASM-MN-214 power
supply via the chassis. Each ASMi-31/R card has two fuses, which protect the
entire system against power failure resulting from a short circuit in one card.
The ASM-MN-214 card cage can accept both AC or DC power supplies.
LED indicators located on the ASM-MN-214 front panel (see Figure 5-3)
show activity when the power supply is connected to the mains plug. The
power supply supports the full card cage with any combination of cards.
AC Supply (100,
115 or 230 VAC) The AC power supply of the ASM-MN-214 is 100, 115 or 230 VAC, ±10%,
47 to 63 Hz.
DC Supply
(-48 VDC) The DC power supply is - 48 VDC (-36 to -72 VDC). It uses a DC/DC
converter module to provide the power required for the cards.
Power Supply
with Redundancy This special ordering option is equipped with two separate power supplies,
operating together and sharing the load of the whole card cage. If either of
the power supplies fails, the other one will continue to supply power to the
full card cage.
Two LED indicators show activity of each power supply. They should both
light when mains power is provided.
Note
It is possible to combine AC and DC power supplies in the same cage.
