Power over Ethernet (PoE) technology provides power and data connectivity to devices such
as Internet telephones, wireless access points, network cameras, security and lighting devices,
and access control devices. According to IDC’s Worldwide Power over Ethernet 2004-2008
Forecast and Analysis report, the Power over Ethernet market revenue is expected to grow at
an 8.9 percent CAGR (compound annual growth rate) over the next five years.

Available in two models (Figure 1)—BayStack 5520-48T-PWR Switch with 48 10/100/
1000BASE-T RJ-45 ports, and BayStack 5520-24T-PWR Switch with 24 10/100/1000
BASE-T RJ-45 ports—they feature four built-in SFP GBIC ports for uplink. Both models
may be stacked with each other or themselves, in stacks of eight units, to achieve a maximum
of 384 10/100/1000 ports for high-density desktop switching. These models will also be able
to stack with the BayStack 5510 Switches and future BayStack 5000 models.

Highest-density Gigabit desktop switching
The BayStack 5520-48T-PWR PoE Switch features 48 10/100/1000
BASE-T RJ-45 ports for desktop switching and four built-in SFP (Small
Form Factor Pluggable) GBIC ports for uplink. Ports 45, 46, 47, and 48
offer configuration flexibility by allowing the network administrator to
configure each port as either 10/100/1000 or make use of the built-in SFP
GBIC. However, power will still be provided from ports 45-48 and can
be used to troubleshoot or power any 802.3af compliant device that only
requires power and not a data connection. As many as eight BayStack
5520-48T-PWR Switches can be stacked to achieve up to 384
10/100/1000 ports for highest-density desktop switching.

The BayStack 5520-24T-PWR PoE Switch offers 24 10/100/1000BASE-T
RJ-45 ports for desktop switching and four built-in GBIC ports for uplink.
Ports 21, 22, 23, and 24 offer configuration flexibility as either a 10/100/

Both BayStack 5520-24T-PWR and BayStack 5520-48T-PWR Switches
may be combined in a single stack for maximum flexibility.

IEEE 802.3af compliant
The BayStack 5520 Switches are IEEE 802.3af compliant. They can
provide Power over Ethernet to any IEEE 802.3af compliant device such as
IP phones, wireless access points, network cameras, security and lighting
devices, and access control devices. The benefit of being interoperable with
standards-based equipment means that customers are not forced to tie
themselves to any one vendor, as the switches have the flexibility to power
multiple vendors’ devices. The BayStack 5520-48T-PWR Switch can
supply power up to 15.4 W per port (with the addition of the BayStack 15
PSU and RPSU module). Without BayStack 15 Power Supply Unit
(PSU), the BayStack 5520-48T Switch would supply an average of 6.5 W
per port (ports can exceed 6.5 W per port as long as the total of all ports
requiring power does not exceed 320 W). The BayStack 5520-24T-PWR
Switch can supply up to 15.4 W per port as well (with the addition of the
BayStack 15 PSU). Without BayStack 15 PSU, the BayStack 5520-24T-
PWR Switch would supply an average of 13 W per port (ports can exceed
13 W per port as long as the total of all ports requiring power does not
exceed 320 W).
