5.4 Power Supply

Power is supplied to the ASM-20/R card from the ASM-MN-214 power supply via the chassis. Each ASM-20/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.

The AC power supply of the ASM-MN-214 is 100, 115 or 230 VAC, ±10%, 47 to 63 Hz.

The DC power supply is -36 to -72 VDC. It uses a DC/DC converter module to provide the power required for the cards.
