Environmental specifications
Table A-4 describes the environmental specifications for the AMS 2100/
2300.
Ethernet specifications
Table A-5 describes the Ethernet specifications for the AMS 2100/2300.
1.Power requirement in the case of the maximum configuration is shown. When planning
facilities such as the uninterrupted power supply (UPS), specify the power factor as 100% for
calculation. Value at 100 V/200 V is shown.
(Example: 300 W=300 VA)
The actual required power may exceed the value shown in the table when the tolerance is
included.
2. The power current of N x 2 described in this table is required for operation by a single power
supply unit.
3. When one of the two power supply units fails, the other power supply provides the total
power to the unit that the two supplies together did before the failure. The operating power
supply therefore draws the same current as the two supplies did before the failure. To make
sure that either power supply can operate in this manner, ensure that the PDUs in the rack can
supply twice the normal power of the units plugged into it.
