Chapter 6 Maintenance
Upgrading the SDRAM Memory Modules
Step 4 Use the following command to copy the file new.image in slot 1 to the flash memory card in slot 0, only
if there is enough memory space for the two images to coexist. If there is not enough memory space,
proceed to Step 5.
Router# copy disk1:new.image disk0:new.image
Note You can also enter the preceding command as copy disk1:new.image disk0:.
Step 5 Use the following series of commands to designate the file new.image (which is on the flash memory
card in slot 0) as the default boot image:
Router# configure terminal
Router(config)# no boot system
Router(config)# boot system flash disk0:new.image
Router(config)# ^z
Router# copy running-config startup-config
Router# reload
When the system reloads, it boots the file new.image from the flash memory card in slot 0.
Upgrading the SDRAM Memory Modules
The Cisco uBR7100 series router has upgradable memory modules on the network processing card
located inside the router. To access these modules, you must remove the top cover of the chassis. Review
the safety information before starting this procedure.
Note SDRAM system memory defaults to 128 MB and can be upgraded to either 192 MB or 256 MB.
(SDRAM packet memory is fixed at 64 MB.)
Warning
Before performing any of the following procedures, ensure that power is removed from the DC circuit.
Statement 1003
Warning
Hazardous voltage or energy is present on the backplane when the system is operating. Use caution
when servicing.
Statement 1034
Warning
Do not touch the power supply when the power cord is connected. For systems with a power switch,
line voltages are present within the power supply even when the power switch is off and the power
cord is connected. For systems without a power switch, line voltages are present within the power
supply when the power cord is connected.
Statement 4
Warning
Hazardous network voltages are present in WAN ports regardless of whether power to the unit is OFF
or ON. To avoid electric shock, use caution when working near WAN ports. When detaching cables,
detach the end away from the unit first.
