Faq (C881-K9)

Are there any hardware upgrade options for C881-K9?

No. The Cisco 880 Series routers are fixed-configuration integrated services routers that do not have hardware upgrade options (except for memory). You must decide the hardware configuration of the router by selecting the desirable product number when you order.

Is the router memory upgradable?

An appropriate amount of router flash memory has been integrated for the different Cisco 880 Series hardware models, and it is not upgradable. DRAM is upgradable on the Cisco 880 Series only. Refer to the Cisco 880 Series data sheets for default memory configurations and upgrade options.

Which Cisco IOS Software releases does the C881-K9 support?

The Cisco 880 Series routers support Cisco IOS Software Release 12.4(20)T and later.

What is the Cisco IOS Software Activation feature?

Software activation authorizes and enables use of a Cisco software feature or feature sets. A special file contained in the device, called a license file, is examined by Cisco software when the device is powered on. Based on the license file installed, Cisco software enables the appropriate feature sets.

Does Cisco Security Manager support the C881-K9?

Cisco Security Manager Version 3.2.1 supports the Cisco 881 and 888 platforms.

Is hardware-based encryption available on the C881-K9?

Yes. Hardware-assisted IP Security (IPsec) Triple Data Encryption Standard (3DES) and Advanced Encryption Standard (AES) encryption is available on the Cisco 880 Series; 128-, 192-, and 256-bit keys are supported for AES.

What kind of 3G modem is integrated with the Cisco 880 Series routers?

When ordered with the 3G part number, the Cisco 880 Series is bundled with a modem branded by Cisco and supplied by Sierra Wireless: AC597E 3G modem for the Code Division Multiple Access (CDMA) network or AC880E 3G modem for the Global System for Mobile Communications (GSM) network.

What is the purpose of the Reset button?

The Reset button is used to restore the router to the default factory settings if pressed within 5 seconds of router power up. Here is how it works: - The router will not react to the Reset button if it is pressed 5 seconds or more after power up. - When the Reset button is pressed within 5 seconds of bootup and there is no valid xxx.cfg file in the flash memory, the router boots up with the factory defaults stored in nonvolatile RAM (NVRAM). - When the Reset button is pressed within 5 seconds of boot up and there is a valid xxx.cfg file in the flash memory, the router boots up with the xxx.cfg file and avoids the startup-config file in NVRAM. The xxx.cfg default configuration file in flash memory also replaces the startup-config file in NVRAM.

What is the function of the virtual auxiliary port?

On the Cisco 880 Series, the console port supports modem control signals. When an external modem is connected to this port, you can use this interface for out-of-band remote management of the router or as a backup WAN interface. An optional RJ-45 to DB-25 male straight-through cable is available to connect modems to this port. A limited set of modems and terminal adapters has been tested, but you can use any Hayes-compatible modem or terminal adapter to connect to this port. The console port behaves like a standard Cisco auxiliary (AUX) port if configured as such and can provide bit rates up to 115.2 kbps.

Can I boot a Cisco IOS Software image and Cisco IOS Software configuration file from the USB flash memory installed on the C881-K9?

During the router reload process, the Cisco 880 Series automatically searches for a bootable Cisco IOS Software image on the USB flash memory if no bootable image is available on the onboard flash memory. A Cisco IOS Software configuration file can be booted from the USB flash memory only if the Cisco IOS Software command boot config usbflash0: is part of the router startup configuration stored in NVRAM.

Old router

Although this one is an updated version of the previous Cisco 881 router, it is too old to meet our new needs.
