Gigabit Ethernet PoE Switch (GSWU) (Figure 2-27
The GSWU blade is a managed 8-port gigabit ethernet PoE switch.
The GSWU blade provides:
●
8 Gigabit Ethernet (10/100/1000) Ports
●
Status LEDs Indicating Link, Speed and Activity
●
802.3af PoE on All Ports Providing up to 15.4W of Power
- Selectable level per port via web-based management interface
●
Auto-MDI/MDI-X Auto Crossover (when auto-negotiation is available)
●
Basis Layer 2 Switch Management
●
QoS
●
802.1Q VLANs
●
802.1p Priority Queuing
●
Port Mirroring
●
802.3x Flow Control
●
Independent VLAN Learning Support
●
TCP/IP Networking Stack
●
Multi-Unit Stacking (multiple blades in a system are managed from the same user interface)
●
Dynamic PoE Control (allows setting the proper PoE classifications for each port to stay within the
system power budget)
●
Switch Management Through Web-Based GUI
●
Software Upgrades Via TFTP
Ports 1 and 8 are the default "uplink" ports. All the user management and stacking is based on this setup.
Multiple-Unit Stacking allows the user the ability to manage multiple GSWU blades in a system as one switch,
instead of individual units and IP adresses. For example, a set of 3 blades would appear to the user interface
as a 24-port switch, instead of 3 8-port switches. Stacking works by assigning a Main Management Blade,
which will provide all the GUI information for all blades in the same stack. The CCPU assigns the Main blade
by issuing an IP address to the Main blade via PAW/PRW during initialization sequence. All other GSWU
blades detected in the system will not be assigned an IP address, thereby signifying them as "add-on" blades.
A single UX5000 system can have up to 12 GSWU blades per system. However, only 3 GSWU blades can be
grouped together to form a single 20-port switch. When more than 3 GSWU blades are present within a
system, the blades not grouped together will not have any of the software feature of the stacked blades. They
will behave as an unmanaged gigabit ethernet switch (only eight 10/100/1000 ethernet ports and PoE Class 3
[lowest power class]). The 2 GSWU blades can be categorized into one "Main" blade, with 2 additional "Add-
on" blades.
