1. SMC8511 Outdoor Cable Modem
Figure 1-1 SMC8511 Outdoor Cable Modem
The SMC8511 Outdoor Cable Modem allows CATV operators to offer commercial broadband IP
data services to customers requiring a hardened DOCSIS 2.0 cable modem suitable for outdoor
environments. Applications include traffic light controllers, security and traffic cameras and other
outdoor devices requiring IP backhaul. The SMC8511 is pictured in Figure 1-1 mounted on a
CATV strand. A flexible pipe mounting system is available as well. See Section 2 of this Manual
Mechanical Installation for details of the mounting assemblies.
Power may be provided to the SMC8511 Outdoor Cable Modem by one of two methods:
•CATV 60-90 VAC (nominal) along with the RF through the F-Connector,
•Power over Ethernet (PoE)1through the water resistant RJ45 Ethernet connector.
In addition, when the SMC8511 Outdoor Cable Modem is powered from the CATV system
through its F-connector interface, it can optionally
provide 24 VDC at 0.5 amps from the Ethernet
port to power the external Ethernet device.

When the SMC8511 is to be CATV line powered the tap must be power passing and the
attenuator value chosen to present the system standard levels to the internal cable modem. A
surge protector (furnished) provides protection from system power events. The laptop computer
utilized for configuration plugs into the Ethernet port.

Above configuration (Fig 3-2) is particularly useful in a lab/shop environment where DOCSIS is
available but without power. A power injector2fed with 24 VDC with at least 1 amp capacity
powers the SMC8511 through the Ethernet port.
Note: Do not exceed 28VDC into the power
injector (no 48 VDC injectors), and do not use a power injector which places DC voltage on the
data leads.
See Section 3.4 for connections.
3.3 Power Output to PoE
When the SMC8511 Outdoor Cable Modem is powered from the CATV system through its F-
connector interface, it can optionally
provide 24 VDC at 0.5 amps from the Ethernet port to
power the external Ethernet device. The wiring /pin connections are given in Figure 3-3, below.
3.4 PoE Wiring
When the SMC8511 Outdoor Cable Modem is powered by means of PoE the connections are
given in Figure 3-3, below.
When the SMC8511 Outdoor Cable Modem is powered by 60-90 VAC CATV system power it can
optionally provide 24 VDC output to an attached Ethernet device. The connections for this
application are also as given in Figure 3-3, below.

Note that this PoE implementation differs from both the IEEE 802.3-2005 and draft IEEE 802.3af
standards.
Do not exceed 28VDC into the power injector (no 48 VDC injectors), and do not
use a power injector which places DC voltage on the data leads.

4.1 SMC8511 Business Class Outdoor Cable Modem
The simplified block diagram of the SMC8511 Outdoor Cable Modem is as shown in Figure 4-1.
The SMC8511 includes a full-featured business class gateway DOCSIS modem.
In standard operation the internal DOCSIS 2.0 cable modem (CM) will obtain an IP
address from the head end DHCP server via the normal CM registration process as
required by the particular CATV system. Once the cable modem completes its
registration process with the DOCSIS head end, the DHCP client function in the
external Ethernet connected device will also obtain its IP address from the DOCSIS
head end DHCP.

5.3 Defaults
The SMC8511 Outdoor Cable Modem (OCM) defaults to the following:
•Bridge Mode
•CPE / remote management interface – disabled
•Web server (GUI)
oRF interface – enabled on port 80 (HTTP) and 81 (HTTPS)
oCPE / remote management interface enabled on port 8080 (HTTP) and 8181
(HTTPS)
•Telnet
oRF interface enabled on port 23
oCPE / remote management interface enabled on port 2323
•LAN IP
oIn Bridge Mode – 192.168.100.1
oIn Router Mode – 20.20.20.1
•DHCP server – Enabled
- 11 -

5.4 Principal Operating Modes
5.4.1 Bridge Mode
When in Bridge Mode:
•The Outdoor Cable Modem (OCM) only requests an RF interface IP address.
•Logon to 192.168.100.1 (Ethernet interface) or RF interface IP to put OCM into Router Mode.
•CPE (Ethernet) interface, Static IP and RIP are disabled.
5.4.2 Router Mode
When in Router Mode:
•Default configuration – OCM requests both an RF interface IP (usually non-routable) and a
CPE / Remote Management interface IP (globally routable).
•By default, the CPE (Ethernet) interface is the RIP source IP.
•The Remote Management page defines ports on which the OCM listens for incoming
management requests to the CPE (Ethernet) interface.
•If ‘Use RF IP as the RIP source IP’ is selected, then the OCM will use RF IP as the RIP
source IP and will not pull a CPE (Ethernet) IP.
oLAN IP becomes CPE / Remote Management IP.
•If a static CPE (Ethernet) IP is configured, DNS values must be assigned. In this
configuration there are three IP addresses assigned to the OCM:
oRF
oCPE / Remote Management
oLAN
