Chapter 1 Product Overview
Field-Replaceable Units
Flash Disks
The flash disk is the default memory device that ships with your Cisco uBR7100 series router.
Cisco uBR7100 series routers support two installed PCMCIA flash disks that contain the default
Cisco IOS software image. Flash disks can be installed in slot 0 and slot 1 of the PCMCIA card slots
located at the back of the router. Slot 0 is the top slot and slot 1 is the bottom slot.
To ensure proper electromagnetic compatibility (EMC), the PCMCIA card slot has a cover that is
secured with a captive screw.
Tip The flash disk slots are physically identified as slot 0 and slot 1, but they are addressed as disk0 and
disk1, respectively, when accessing the flash disks with Cisco IOS commands.
For procedures that explain the installation and use of the flash disk, see the “Flash Memory Card Usage”
section on page 6-5. Also see the Using the Flash Disk document that accompanies every flash disk
shipped from the factory.
Table 1-2 lists the flash disk memory options and their product numbers.
