5.2 Power Supply
The FOM-E1/T1/R card is powered from the ASM-MN-214 power supply through
the chassis. Each FOM-E1/T1/R card has two fuses that protect the entire system
against power failure due to a short circuit in one card (see
Figure 5-4 ). The
ratings of the fuses are 1A, 250V and 50 mA, 250V.
The ASM-MN-214 card cage can accept both AC and DC power supplies. LED
indicators located on the ASM-MN-214 front panel (see
Figure 5-2
) 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.
