modems. The default communications settings are:
• 9600 bps
• 8 data bits
•1 stop bit

Random Access Memory (RAM)
The AR450S has 64MB of SDRAM provided on a single DIMM. 128MB and
256MB ECC SDRAM are also supported. See your authorised Allied Telesyn
distributor or reseller for upgrade options. Other supplier’s DIMMs are not
approved, and therefore not supported, but may function correctly.
The amount of DRAM present in a router can be checked using the command:
show system
The DRAM and FLASH fields show the amounts of DRAM and flash memory,
respectively.

• SHA-1 and MD-5 hashing support
• RSA and DH public key support.
