Before proceeding, ensure that you have the proper tools and ESD-prevention
equipment available. To upgrade SDRAM, you will install DIMMs in one or two
banks (U15 and U18). Table 15 and Table 16 list the various available
configurations of SDRAM DIMMs, the number of DIMMs for each
configuration, and the SDRAM banks they occupy. Note which banks you should
use, given the combinations of available DIMM sizes and the maximum SDRAM
you require.
Note Depending on the configuration of your router and the protocols and features your
system is running, you might require more than the default SDRAM provided.
Upgrade SDRAM based on your requirements and the information in Table 15
and Table 16.
