Q. How does the 1-port GE or 1-port SFP (combo-port) work?
A. A combo port means that it is one logical interface that can have one of two physical interfaces. You can use either the RJ-45 copper Ethernet port or the SFP port. Both of these physical ports are internally addressed as one interface (that is, GigabitEthernet8), and you have to configure the media type under the interface to select the one you want to use.
Q. What are the hardware options for the Cisco 890 Series?
A. The 4-port Power over Ethernet (PoE), 802.11n wireless access point, and memory are hardware options. You can select these options when ordering.
Q. Can the PoE be upgraded after ordering?
A. Yes, you can upgrade the PoE on all models except the C892FSP-K9, which does not support PoE at all. For all Cisco 890 Routers, the product ID (PID) for the PoE upgrade is 800-IL-PM-4=. This PID comes with two power supply options: 80 or 125 watts. The older CISCO890 requires the 80-watt option, whereas the newer C890 requires the 125-watt option.
Q. Why do some routers use 80 watts and others 125 watts for PoE?
A. The 80-watt power supply is used in addition to the standard 60-watt power supply, so you will have two power supplies connected to the router. For the newer routers we combined these two power supplies into the one 125-watt power supply (hence we have a 4-pin connector). Both models support the base router as well as 4 ports with standard PoE.
Q. Can I upgrade the wireless after ordering?
A. No, you cannot upgrade the wireless.
Q. Can I upgrade the memory after ordering?
A. Yes, we have memory upgrade kits for all Cisco 890 Routers. Please refer to Table 1 to see which memory upgrade kit is compatible with your model.
Q. Do Cisco 890 Series Routers support third-generation (3G) and voice ports?
A. No. Cisco 890 Series Routers do not support 3G and voice ports.
Q. Is it possible to add voice support to a Cisco 890 Series data model?
A. No. With the Cisco 890 Series, IP phones can be connected to the integrated switchports to register with a centrally located Cisco Unified Communications Manager.
Q. What is the Universal Serial Bus (USB) port being used for?
A. USB 2.0 ports are available on the Cisco 890 Series. These ports enable important security and provisioning capabilities, including secure device authentication, storage of removable credentials for establishing secure VPN connections, secure distribution of configuration files, bulk flash memory storage for files and configuration, and booting from the USB. The Cisco 890 Series supports two types of USB devices: USB flash and USB eToken. For a list of supported USB flash and eToken devices, refer to: http://www.cisco.com/en/US/prod/collateral/modules/ps6247/product_data_sheet0900aecd80232473.html.
Q. What is the purpose of the Reset button?
A. The Reset button is used to restore the router to the default factory settings if pressed within 5 seconds of router bootup. Here is how it works:
• The router will not react to the Reset button if the button is pressed after the 5 seconds of bootup.
• 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 bootup 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.
Q. What is the function of the auxiliary port?
A. On the Cisco 890 Series, an external modem can be connected to the auxiliary port for any asynchronous dialup connection. 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 as an orderable option 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.
Q. What Cisco IOS Software image and feature sets do you offer for the Cisco 890 Series?
A. The Cisco 890 Series supports universal images and one feature set. A universal image includes all features supported by a given platform. The active feature set is enabled using the Cisco software activation feature.
• The Advanced IP Services feature set is supported by the Cisco 890 Series using the Cisco software activation feature.
Q. What is the Cisco software activation feature?
A. Software activation authorizes and enables the 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 set(s).
Q. What features require a software license and activation on the Cisco 890 Series?
A. The default and only feature set for the Cisco 890 Series is Advanced IP Services. The appropriate license file is installed on the platform by Cisco manufacturing to support the default feature set. In addition, feature licenses exist for memory, Cisco Wide Area Application Services Express (WAASx), and Secure Sockets Layer (SSL). These feature licenses are listed at the bottom of the data sheet. http://www.cisco.com/en/US/prod/collateral/routers/ps380/data_sheet_c78-519930.html.
Q. Can I boot a Cisco IOS Software image and Cisco IOS Software configuration file from the USB flash memory installed on a Cisco 890 Series Router?
A. During the router reload process, the Cisco 890 Series Router 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. You can boot a Cisco IOS Software configuration file 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.
Q. How are factory default configurations restored on the Cisco 890 Series?
A. You can restore Cisco 890 Series factory default configurations by using the Cisco Configuration Professional application or by using the Reset button on the platform. Refer to the question "What is the purpose of the Reset button?" in the "Hardware Features" section to learn more about restoring factory default configurations using the Reset button.
Q. Does the Cisco 890 Series support any out-of-band management capabilities?
A. The Cisco 890 Series supports out-of-band management capabilities using the auxiliary port with an external modem connected to it or using the standard RJ-45 console port.
Q. Are the auxiliary port and the console port different ports?
A. On the older CISCO890 these two ports were separate RJ-45 ports, but on the newer C890 Routers these two ports are combined in one physical RJ-45 port.
Q. Can I use the ISDN or V.92 interfaces on the Cisco 890 Series as a primary interface?
Q. Is hardware-based encryption available on the Cisco 890 Series?
