POE DELAY CONFIG
The PoE delay function allows an administrator to program a startup sequence for your PoE-compliant
devices and eliminate potential problems caused by the increased power draw at startup. The sequential
power-up guarantees a smooth startup procedure for all connected networking devices (i.e., your PoE-
enabled network cameras). The restart time allows to cut power to the PSE ports of the Intellinet Network
Solutions switch in order to restart a connected powered device. This can be used in order to preventively
reboot powered devices to keep them from failing.
Item Description
Restart Weeks
Selection
Despite the name of this item, you do not dene the weeks, but the weekday on which you
wish power to be cut to the connected device.
Restart Time Dene the time of day when you want power to be cut to the connected powered device.
The time is entered in 24 hour time format, for example 15:00:00 represents 3 pm.
Port Delay
Time
Dene how long the switch will have to wait before it activates the port(s) after a system
restart. Enter the delay value in seconds.
STP
The Spanning Tree Protocol (STP) can be used to detect and disable network loops and to provide backup
links between switches, bridges or routers. This allows the switch to interact with other bridging devices in
your network to ensure that only one route exists between any two stations on the network. It also provides
backup links, which automatically take over when a primary link goes down. The spanning tree algorithms
supported by this switch include these versions:
• STP – Spanning Tree Protocol (IEEE 802.1D)
• RSTP – Rapid Spanning Tree Protocol (IEEE 802.1w)
• MSTP – Multiple Spanning Tree Protocol (IEEE 802.1s)
The IEEE 802.1D Spanning Tree Protocol and IEEE 802.1w Rapid Spanning Tree Protocol allow for the blocking
of links between switches that form loops within the network. When multiple links between switches are
detected, a primary link is established. Duplicated links are blocked from use and become standby links.
The protocol allows for the duplicate links to be used in the event of a failure of the primary link. Once the
Spanning Tree Protocol is congured and enabled, primary links are established and duplicated links are
blocked automatically. The reactivation of the blocked links (at the time of a primary link failure) is also
accomplished automatically without operator intervention. This automatic network reconguration provides
maximum uptime to network users. However, the concepts of the Spanning Tree Algorithm and protocol
