Introducing the Switch
The dual-personality ports support either auto-sensing 10/100/1000Base-T
RJ-45 connectors, or SFP (mini-GBIC) transceivers. The SFP ports do not
support PoE/PoE+. If any of the SFP ports are used, the corresponding RJ-45
port will not be supplied with PoE/PoE+ power and will be disabled. For more
information regarding the PoE/PoE+ capabilities of the 3500yl, 3500 PoE or
3500yl-PoE+ switches, see the HP ProCurve Power over Ethernet (PoE/PoE+)
Planning and Implementation Guide which is on the HP ProCurve Web site,
www.hp.com/go/procurve/manuals.
The 3500 and 3500yl switches can be connected to an HP ProCurve 620
Redundant and External Power Supply (RPS/EPS) and receive redundant
power from that unit. If the internal power supply in the switch fails, the RPS/
EPS unit will immediately provide all the power necessary to keep the switch
running. This includes power to run the switch and PoE power. If maximum
PoE power is being used on all 48 ports, a 620 RPS/EPS is necessary to provide
full power to the second 24 ports, and in this case, there is no redundancy.
The 6200yl switch can be connected to the HP ProCurve 620 Redundant and
External Power Supply (RPS/EPS) and receive redundant power from that
unit. If the internal power supply in the switch fails, the RPS/EPS unit will
immediately provide the power necessary to keep the switch running. The
6200yl does not support PoE power.
The 3500yl-PoE+ switches can be connected to an HP ProCurve 630
Redundant and/or External Power Supply (RPS/EPS) and receive redundant
power from that unit. If the internal power supply in the switch fails, the RPS/
EPS unit will immediately provide all the power necessary to keep the switch
running. This includes power to run the switch and PoE+ power. If maximum
PoE+ power is being used on 24 ports, a 630 RPS/EPS is necessary to provide
power to the second 12 ports, and in this case, there is no redundancy.
The 6200yl, 3500yl and 3500 switches are designed to be used primarily as a
high-density wiring closet or desktop switch. These switches can directly
connect computers, printers and servers to provide dedicated bandwidth to
those devices. By connecting the switch to hubs, other switches or routers,
they can be used to build a switched network infrastructure. In addition, the
3500yl switches offer full network management capabilities.
