The new Catalyst 4000 family 48-port Inline Power 10/100BaseT Ethernet switching module delivers new Fast Ethernet enhancements that will carry customers forward into the new era of multiservice networking. The Inline Power 10/100BaseT Ethernet switching module supports up to 48 ports per module. Along with phone discovery, these modules support autosensing/autonegotiation to determine the speed and duplex mode of the attached device.
Inline power is 48-volt DC power provided over standard category 5 UTP cable up to 100 meters. Instead of requiring wall power, terminal devices such as IP telephones can utilize power provided from the Catalyst 4000 switch. This capability gives the network administrator centralized power control, which translates into greater network availability.
The Inline Power 10/100BaseT Ethernet switching module supports up to 48 ports per module (RJ-45 interfaces). Along with phone discovery, these modules support autosensing/autonegotiation to determine the speed and duplex mode of the attached device. The Catalyst 4003 uses the Catalyst Inline Power Patch Panel to provide inline power. The Catalyst 4006, with support for up to 240 multiservice ports, directly provides inline power. To support the new demand for phone power on the Catalyst 4006, Cisco has developed a new optional auxiliary DC power shelf that supplies the Catalyst 4006 with the 48 volts needed for inline power.
The Catalyst 4000 Inline Power 10/100BaseT Ethernet switching module features: 48 ports 10/100BaseTX per module (RJ-45): Up to 240 10/100 Fast Ethernet ports per Catalyst 4006 family switch Inline Power: 48-volt DC power provided over standard category 5 UTP cable up to 100 meters Phone Discovery: Catalyst 4000 switch automatically detects the presence of an IP phone and supplies inline power Auxiliary VLAN via 802.1Q: Catalyst 4000 switch automatically segments phones and data endpoints into separate logical networks Support for IEEE 802.3u autonegotiation process that allows the switch to negotiate speed (10 or 100 Mbps) or duplex mode (half or full duplex) with an attached device Capacity of up to five modules per platform: Modules require one slot, can be "mixed and matched" with other switching modules, and can be hot-swapped or added as needed without interrupting the Catalyst 4000 switch Superior traffic management with large per-interface buffers and multiple priority queues Support for multiple active MAC addresses (up to 16,000) on a switching port and can be dynamically allocated to any port Spanning-tree algorithm on logical VLANs for fault-tolerant connectivity: Modules capable of supporting up to 1000 VLANs Extensive management tools using Simple Network Management Protocol (SNMP) network management platforms such as CiscoWorks for Switched Internetworks Four RMON groups: Statistics, history, alarms, and events supported in hardware
