Installing the Switch
Sample Network Topologies
2-24
In the illustration above, 2530-24G-PoE+ Switches with PCs, printers, and
local servers attached, are both connected to a non-PoE switch. The devices
attached to the two 2530-24G-PoE+ Switches can now communicate with each
other through the non-PoE switch. They can also all communicate with the
server that is connected to a 1000BASE-T port on the 2530-24G Switch.
As shown in the illustration above, the IP telephones have been inserted in
between the 2530-24G-PoE+ Switch and the PCs, and wireless access points
(WAPs) have been connected to the 2530-24G-PoE+ Switches. Both the
telephones and WAPs will receive PoE+ power from each of the switches.
Only devices directly connected to PoE switches can receive PoE power.
Devices connected to the non-PoE switch cannot receive PoE power.
Because the HP 2530 Switches have the Auto-MDIX feature, the connections
between the switches and end nodes or servers can be through category 5
straight-through or crossover twisted-pair cable. Category 3 or 4 cable can
also be used if the connection is 10 Mbps only. In all cases, the device ports
must be configured to auto negotiate the link characteristics for this feature
to work.
The connections between the switches are through fiber-optic cabling
connected to Gigabit transceivers. All the devices on these network segments
can access other network resources that are connected elsewhere on the
network. Always remember when connecting fiber-optics that all components
match in specification.
