Connect Management Cable
The Cisco 675 comes with a special serial cable to connect the serial port of a computer to the Cisco 675 management port for out-of-band management. The cable is gray with a DB9 connector on one end an an RJ type modular connector on the other end. This is the only way to issue commands to the Cisco 675 while in bridging mode. If you have previously used your modem in routing mode, you should be able to telnet to the modem as you have in the past. The provided management cable should work with an Intel-based PC or similar system which has a DB9 male COM port. Connect the DB9 end to the PC COM port and the other end to the Cisco 675 management port. Use Hyperterm (hypertrm.exe) or a similar program to connect "direct to COM1" or the appropriate port at 38400bps (or 9600), 8 bits, 1 stop, no parity, no flow control. On a Macintosh, an adapter cable is required. If the connection doesn't work using the Mac serial port, try the parallel port. The difference between those two ports is cross-over of RD and TD (DCE vs. DTE). Consult your modem manual for further information.
Configure DSL Modem
You must be running CBOS version 2.2.0 or higher. Use the CBOS "show version" command to see your CBOS version. If you need to upgrade, consult your documentation or call NeTrack. In the configuration example below, use the following substitutions:
ip_address is the single IP address you were given or the first usable IP address in your assigned block. For example, if you are assigned the block 192.168.15.40 through 192.168.15.47, the ip_address you would use here is 192.168.15.41.
DSL_phone is the telephone number for your DSL service with area code and without punctuation, e.g. 3039380188.
net_mask is the IP block network mask.
cr is a carriage return.Do all of the following steps that apply. You can do both step 2 and step 3.
1) In all cases, do initial configuration:
cbos>enable Password:cr cbos#set nvram erase Erasing Running Configuration. You must use "write" for changes to be permanent. cbos#write NVRAM written. cbos#reboot Hello! Expanding CBOS image... CBOS v2.2.0.000 cr User Access Verification Password:crcbos>enable Password: cbos#set ppp wan0-0 ipcp ip_address PPP wan0-0 IPCP Address set to ip_address cbos#set ppp wan0-0 dns 0.0.0.0 PPP wan0-0 DNS Server Addresses set to 0.0.0.02) If you were assigned an IP block and want to use static IPs internally:
cbos#set int vip0 ip ip_address Virtual IP Address now changed cbos#set int vip0 mask net_mask Virtual Netmask now changed3) If you want to use NAT/DHCP internally:
cbos#set nat enabled NAT is now enabled You must use "write" then reboot for changes to take effect. cbos#set dhcp server enabled DHCP Server enabled4) And for all cases, save the config and reboot:
cbos#write NVRAM written. cbos#rebootConnect WAN
Simply connect the Cisco 675 WAN port to the wall telephone outlet with the normal RJ45 cable provided with the modem. The WAN link light should light solid green. A flashing WAN link light indicates either a problem with your cable, wall outlet, home/office wiring to the wall outlet, or the DSL service.
If your WAN link light will not stop flashing and stay on solid, check to make sure the Cisco 675 is plugged directly into your telephone line as the first thing. Plug telephones and modems into the Cisco 675. Never plug the Cisco 675 into the telephone port on a standard modem or behind a telephone switching device. If your WAN link light still flashes, call U S WEST at 888-333-0131.
Connect workstation or LAN
The Cisco 675 comes with a cross-over 10baseT Ethernet cable (YELLOW). It is designed to connect directly between the Cisco 675 Ethernet port and the Ethernet interface on a single computer workstation. To connect the Cisco 675 to a 10baseT LAN hub/concentrator, the Cisco 675 must either be connected to a non-cross-over uplink port on the hub using the cross-over cable provided or connected to a regular node port on the hub using a regular non-cross-over 10baseT cable (not provided).
Configuration workstations
Configure all workstations to get their IP address dynamically unless there is a specific requirement for a static IP address. If you have requested and been assigned a block of static IP addresses, you may use any IP address in the block except that which are already in use by the DSL modem when you configured it above, in use by another workstation you already configured, or the very first and last IP in the block. Please refer to the Mac and Windows specific configuration notes.
