All FGS and FGS-STK devices provide high port density and Gigabit Ethernet (GbE) uplinks within a
compact form factor. Standard FGS models ship from the factory with 128 MB of SDRAM. FGS-STK
models ship from the factory with 256 MB of SDRAM. Since all devices that will run the stacking
software must have 256 MB of memory, the stacking upgrade kit includes the stacking EEPROM
and 128 MB of additional memory to fulfill this requirement. For information about how to upgrade
your standard FGS model see Chapter 3, “EPREM Upgrade for FastIron GS Devices”
You can order FGS and FGS-STK devices with Power over Ethernet (PoE) factory installed, or you
can upgrade your device to include PoE at a later date. You can also upgrade your FGS devices to
support stacking by ordering the stacking upgrade kit. For more information refer to “Stacking
Upgrade for the FastIron GS” on page 47.
FGS-STK devices ship with full stacking support included. For information about how to connect
stackable devices into an IronStack, refer to “Installing FastIron GS-STK stackable devices” on
page 33.
FGS and FGS-STK POE devices provide electrical power over existing Ethernet cables, supporting
the need for integrated data, voice, and video applications.
POE applications
Brocade FGS POE devices provide Power over Ethernet (POE), compliant with the standards
described in the IEEE 802.3af specification for delivering in-line power. The 802.3af specification
defines the standard for delivering power over existing network cabling infrastructure, offering
multicast-enabled full streaming audio and video applications for converged services, such as
Voice over IP (VoIP), WLAN access points, IP surveillance cameras, and other IP technology devices.
POE technology eliminates the need for an electrical outlet and dedicated UPS near IP powered
devices. With power sourcing devices, such as Brocade FGS624P-POE and FGS648P-POE models,
power is consolidated and centralized in the wiring closets, improving the reliability and resiliency
of the network. Because POE can provide power over Ethernet cable, power is continuous, even in
the event of a power failure.
