SDRAM Memory

Warning Only trained and qualified personnel should be allowed to install, replace, or service this equipment.

Statement 1030

SDRAM memory consists of three DIMMs (on the network processor card) that contain the packet and system memory. By default, each chassis comes with 64 MB of fixed packet memory and 128 MB of upgradable system memory. SDRAM system memory is upgradable to 256 MB; packet memory is fixed at 64 MB.

For more information on the network processor, see the “Network Processor Card” section on page 1-15. For information about replacing the SDRAM, see the “Upgrading the SDRAM Memory Modules” section on page 6-11.

Note For information on how to replace the SDRAM memory, refer to the following URL:

Table 1-3lists the SDRAM product numbers for both packet memory and system memory. Where applicable, product numbers are for spares (to replace existing memory configurations) and for upgrades (to upgrade the existing memory configuration to a larger value).

		1 64 MB DIMM in slot DIMM 2	original configuration)
			MEM-7120/40-64S= (to upgrade the default
			configuration)
256	MB	2 128 MB DIMMs; 1 in each slot	MEM-7120/40-256S (when ordering the

			configuration)

1.Packet memory is fixed at 64 MB on the Cisco uBR7100 series routers.

2.This is the default memory configuration for all Cisco uBR7100 series routers.

Note The amount of memory installed in slot DIMM 1 must be greater than or equal to the amount of memory installed in slot DIMM 2. If desired, slot DIMM 2 can be zero.

Slot DIMM 0 is used exclusively for packet memory and is fixed at 64 MB in the factory.
