switches contain two rows of LEDS that provide information about connection
speed, data activity, and duplex operation mode.
Power (POWER) LED
• Green — The switch is powered on.
• Off — The switch is not powered on.
10/100Base-T Ports Link/Activity (SPD/LNK/ACT) LED
• Steady green — A 100-Mbps link has been established, but no data is being transmitted or
received.
• Blinking green — A 100-Mbps link has been established and data is being transmitted or
received.
• Steady amber — A 10-Mbps link has been established, but no data is being transmitted or
received.
• Blinking amber — A 10-Mbps link has been established and data is being transmitted or
received.
• Off — No link established.

1000Base-T Ports Link/Activity (SPD/LNK/ACT) LED (2324 only)
• Steady green — A 1000-Mbps link has been established, but no data is being transmitted or
received.
• Blinking green — A 1000-Mbps link has been established and data is being transmitted or
received.
• Off — No link established.
Duplex Mode/Collisions (FDX/HDX) LED
• Steady green — The port is operating in full-duplex mode.
• Blinking green — Collisions are occurring on the port.
• Off — The port is operating in half-duplex mode.

Introduction 9
Connecting Devices
RJ-45 Switch Ports
RJ-45 connectors are located on the front panel of the switch.
NOTE: Ensure that Category 5E (CAT 5E) cabling is used for connecting devices at 1000-Mbps Gigabit
Ethernet speed.
All ports can negotiate full- and half-duplex modes automatically. The 10/100base-T ports negotiate
full/half duplex and the 1000base-T ports operates in full-duplex mode only. These switching ports
allow users to connect the switches to 10Base-T and 100Base-T devices on ports 1-16 (2216), ports
1-24 (2224, 2324) and 1000Base-T devices on uplink ports 25 and 26 on the 2324.
Connecting Switches to Each Other
Each port supports Auto MDI and MDIX functionality. When cascading with other switches or
hubs, each port can connect directly to a switch or hub with straight-through twisted-pair cable
(see Figure 1-4).
NOTE: Do not connect two switches together with more than one cable. Using multiple cables to
connect switches can create a loop and cause loss of network connectivity.
Figure 1-4. Cascading Switches
Connecting Switches to Other Devices
By connecting a switch to other devices, you can form a small network. All the RJ-45 ports support
Auto MDI/MDIX and therefore automatically detect the type of cable used to connect the network
device. Crossover or straight-through networking cables can be used to connect PCs as well as other
networking devices like hubs or routers to the switch. All ports on the switch automatically
negotiate speed and whether to operate in full duplex or half duplex.

Class-of-Service
The switch supports tag-based prioritization following the IEEE 802.1p standard. The eight levels
of IEEE 802.1p priority are mapped to the two priority queues of each port. For each port, the two
priority queues are scheduled following a Weighted Round Robin scheme.
