5.2 Power Supply
Power is supplied to the RIC-E1/R card from the ASM-MN-214 power supply via
the chassis. Each RIC-E1/R card has two fuses (F5 and F6), which protect the entire
system against power failure resulting from a short circuit in one card. The rating of
the fuses is 500 mA, 250V, slowblow (see
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
) 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
The AC power supply of the ASM-MN-214 is 100, 115, or 230 VAC, ±10%,
47 to 63 Hz.
DC Supply
The DC power supply is -48 VDC (-36 to -72 VDC) or 24 VDC (18 to 32 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.
It is possible to combine AC and DC power supplies in the same cage.
