    (called XBOOT) has been added to the ROM on the RFF models. The boot-helper image is a small subset of Cisco IOS software that supports only a subset of the interfaces and the WAN protocols. RFF ROM supports the following WAN interfaces. (These are all onboard interfaces, not WAN-interface-card interfaces.)

  • Page 12

    Router Memory Run-From-RAM Architecture With RFR, the Cisco IOS image is stored in Flash memory (usually in compressed form), but is loaded into RAM before being used to operate the router. The running software image then resides in RAM, so a new software image can be downloaded and copied over the software image stored in Flash memory.

    Wall-Mounting the Router Wall-Mounting the Router Cisco 1600 series routers can be wall-mounted by using two number-six, 3/4-inch screws (not included) and the molded mounting brackets on the bottom of the router (see Figure 3-7). Caution If you install the screws in drywall, use hollow wall-anchors (1/8 inch by 5/16 inch) to secure the screws.

  • Page 47

    Wall-Mounting the Router Hang the router on the screws by the mounting brackets so that the following Step 2 conditions are met: • The front panel LEDs face upward and are easily visible. You will use these LEDs to verify that the router is operating properly. Mounting the router in this position also reduces strain on the network cable connections.
