Memory Recommendations and Requirements (continued)
Memory
Recommendation/
With software releases 7.5(1) and later, 64-MB DRAM may not provide
adequate free memory for all configurations. With large, existing configurations
using many features, or when enabling new features available in release 7.5 and
later, 64-MB DRAM might not be enough memory. We recommend upgrading to
128-MB DRAM to ensure that adequate free memory is available to the system at
all times.
Software release 7.6(4) and later 7.6(x) releases are too large to fit in the 64-MB
DRAM that originally shipped on some Supervisor Engine 1A modules. You
must upgrade to 128-MB DRAM.
With Catalyst software releases 8.1(1) and later, your Supervisor Engine 1A
configuration requires 128-MB DRAM.
