VoIP
Voice over IP (VoIP) is the convergence of traditional telephony networks with data networks, utilizing
the existing data network infrastructure as the transport system for both services. Traditionally, voice is
transported on a network that uses circuit-switching technology, whereas data networks are built on
packet-switching technology. To achieve this convergence, technology has been developed to take a
voice signal, which originates as an analog signal, and transport it within a digital medium. This is
done by devices, such as VoIP telephones, which receive the originating tones and place them in UDP
packets, the size and frequency of which is dependant on the coding / decoding (CODEC) technology
that has been implemented in the VoIP telephone or device. The VoIP control packets use the TCP/IP
format.
IP surveillance cameras
IP surveillance technology provides digital streaming of video over Ethernet, providing real-time,
remote access to video feeds from cameras.
The main benefit of using IP surveillance cameras on the network is that you can view surveillance
images from any computer on the network. If you have access to the Internet, you can securely
connect from anywhere in the world to view a chosen facility or even a single camera from your
surveillance system. By using a Virtual Private Network (VPN) or the company intranet, you can
manage password-protected access to images from the surveillance system. Similar to secure
payment over the Internet, images and information are kept secure and can be viewed only by
approved personnel.
Installing PoE firmware
NOTE
The PoE firmware upgrade feature is not supported in FIPS mode on Brocade devices.
PoE firmware is stored in the PoE controller of the FastIron switch. You can install PoE firmware from
the TFTP server on a FastIron switch with the CLI command. To do so, you should have a valid
firmware image on the TFTP server.
NOTE
You can install PoE firmware only on one switch at a time. Therefore, to install PoE firmware on a
stacking unit, you need to install it individually on every switch of the stack.
NOTE
The CLI syntax to install PoE firmware is different on FSX and FCX platforms.
FSX platform
To install PoE firmware on a FSX platform, enter a command such as the following.
device#inline power install-firmware module 1 tftp 10.120.54.161 fsx_poe_07400.fw
Syntax: inline power install-firmware module slot tftp ip-address filename
Slot refers to the slot of the PoE module.
ip-address refers to the IP address of the TFTP server.
