Switch Memory
The available memory for the FC 6164 is as follows:
• Main memory: 16 MB per switch
• Flash memory: 4 MB per bank, with 2 banks in the 2250 switch
(mirrored for redundancy)
Power Supply
The 2250 switch is powered on when the power cable is connected to the
switch and to a power source. The switch automatically performs a power
on self test (POST), which is a diagnostic test that takes approximately 2
minutes.
The 2250 switch has a universal power supply capable of functioning
worldwide without voltage jumpers or switches. The power supply module
is autoranging in terms of accommodating input voltages and line
frequencies.
Environmental Specifications for each Switch
The acceptable environmental ranges for the 2250 switch are the same as
for the entire FC 6164, and are listed under “Thermal Characteristics” on
page 16.
