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 Figure 5-6).

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 5-5)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.

Note It is possible to combine AC and DC power supplies in the same cage.
