Power over Ethernet (POE) applications
B08S and B16S devices with Power over Ethernet (POE) are compliant with the
standards described in the IEEE 802.3af specification for delivering in-line power.
The 802.3af specification defines the standard for delivering power over existing
network cabling infrastructure, enabling multicast-enabled full streaming audio and
video applications for the following converged services:
v Voice over IP (VoIP)
v
WLAN access points
v IP surveillance cameras
v IP technology devices
POE technology eliminates the need for an electrical outlet and dedicated UPS near
IP powered devices. With POE power sourcing devices, power is consolidated and
centralized in the wiring closets, improving the reliability and resiliency of the
network. Because POE can provide power over Ethernet cable, power is
continuous, even in the event of a power failure.
For POE port density, see “POE port density” on page 4.
For more information about POE and how to configure it, see the Configuration
Guide .
Support for IPv6 modules
The B08S and B16S support IPv6 management and interface modules starting with
software release 04.0.00.
For details about IPv6 modules, see the following sections in this chapter:
v
“IPv6 hardware support guidelines”
v “Hardware features”
v
“Interface modules” on page 13
IPv6 hardware support guidelines
Note the following guidelines and restrictions with IPv6 Management and Interface
modules:
v IPv4 interface modules must only be matched with IPv4 management modules
and IPv4 interface modules within the same chassis.
v
If you install dual IPv6 management modules, the modules must be identical. For
example, you cannot install one 2-port management module and one 8-port
management module together in the same chassis. The modules must be of
like-kind.
Hardware features
The s-series switches include the following major hardware components:
v Chassis
v Management module with optional support for dual management modules that
provide 100% redundancy
v Separate switch fabric modules
v
Interface modules
