Product Descriptions

DRAM

DRAM stores routing tables, protocols, and network accounting applications. The standard

RSP7000 conﬁguration is 16 megabytes (MB) of DRAM, with up to 128 MB available through

single in-line memory module (SIMM) upgrades.

Note

obtain the most current vendor information, obtain the list from Cisco Information Online (CIO) or

the Technical Assistance Center (TAC). (See the section "Software Prerequisites" on page 11.)

NVRAM

The system conﬁguration, software conﬁguration register settings, and environmental monitoring

logs are contained in the 128-kilobyte (KB), nonvolatile random-access memory (NVRAM), which

is backed up with built-in lithium batteries that retain the contents for a minimum of ﬁve years. When

replacing an RSP7000, be sure to back up your conﬁguration to a remote server so you can retrieve

it later.

Caution

Transfer Protocol (TFTP) ﬁle server so you can retrieve it later. If the conﬁguration is not saved, the

entire conﬁguration will be lost—inside the NVRAM on the removed RSP7000—and you will have

to reenter the entire conﬁguration manually. For instructions on how to save the conﬁguration ﬁle,

refer to the section "Saving and Retrieving the Conﬁguration File" on page 12. This procedure is not

necessary if you are temporarily removing an RSP7000 you will reinstall; lithium batteries retain the

conﬁguration in memory until you replace the RSP7000 in the system.

Flash Memory

The imbedded or PCMCIA card-based Flash memory allows you to remotely load and store multiple

Cisco IOS and microcode images. You can download a new image over the network or from a local

server and then add the new image to Flash or replace the existing ﬁles. You can then boot routers

either manually or automatically from any of the stored images. Flash memory also functions as a

TFTP server to allow other servers to boot remotely from stored images or to copy the stored image

into their own Flash memory.

Note

replacing an RP with an RSP7000, you must reformat the Flash memory card if you want to use it

with your new RSP7000. You must install the RSP7000 in the 7000 RSP slot, have an RSP7000

Chassis Interface (RSP7000CI) installed in the 7000 CI slot, and be running Cisco IOS Release

10.3(9), or later, Release 11.0(6), or later, or Release 11.1(1) or later, for the new RSP7000 to work

properly. Using the RSP7000, you cannot read data on the RP's Flash memory card, nor can you use

it as bootable media. You must reformat the RP's Flash card before you can use it with the RSP7000.

Flash memory cards formatted on the RP-based systems (7000 series routers) are formatted

differently from Flash memory cards formatted on RSP-based systems (7500 series routers).

Caution

loss of important data that might be stored on a Flash memory card, proceed carefully. If you want

to save the data on a Flash memory card, copy the data to a server before you format the card.
