Introducing the Switch
One slot is provided in the back of the device to support a four port (two fixed
CX4 ports and two X2 transceiver ports) 10 Gigabit per second Ethernet (10-
GbE) module to provide box connectivity to other switch boxes, to a 10
Gigabit per second concentrator or to any Ethernet compatible uplink.
The Series 3500yl Switches are also designed to support Power over Ethernet
(PoE) technology. The switches support 802.3af standard devices and some
pre-standard PoE devices. For a list of these devices, see the FAQs for your
switch model. This feature is the default and you must disable it if you do not
want to use it. (Refer to the Management and Configuration Guide which is
on the ProCurve Web site, www.procurve.com. (See
The dual-personality ports have either auto-sensing 10/100/1000Base-T RJ-45,
or mini-GBIC connectivity. The mini-GBIC ports do not support PoE. If any of
the mini-GBIC ports are used the corresponding RJ-45 port will not be supplied
with PoE power and will be disabled. For more information regarding the PoE
capabilities of the Series 3500yl Switches, see the ProCurve Power over
Ethernet (PoE) for zl and yl Products Planning and Implementation Guide.
The Series 3500yl Switches can be connected to a 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 just to provide full
power to the second 24 ports, and in this case, there is no redundancy.
The Series 6200yl Switch can be connected to the 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
only includes power to run the switch. The 6200yl does not support PoE power.
These 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, and
can build a switched network infrastructure by connecting the switch to hubs,
other switches, or routers. In addition, the Series 3500yl Switches offer full
network management capabilities.
