10/100/1000 Ports

The 10/100/1000 ports use RJ-45 connectors with Ethernet pinouts. The maximum cable length is 328 feet
(100 meters). The 100BASE-TX and 1000BASE-T traffic requires twisted pair (UTP) cable of Category 5
or higher. The 10BASE-T traffic can use Category 3 cable or higher.

PoE, PoE+, Cisco UPOE and Cisco UPOE+ Ports

The PoE+ and Cisco Universal Power Over Ethernet (Cisco UPOE and Cisco UPOE+) ports use the same
connectors as described in
• PoE+ ports: Support for IEEE 802.3af-compliant powered devices (up to 15.4 W PoE per port) and
• Cisco UPOE ports: Support for Type 1 (IEEE 802.3af), Type 2 (IEEE 802.3at), Type 3 (IEEE 802.3bt),
• Cisco UPOE+ ports: Support for Type 1 (IEEE 802.3af), Type 2 (IEEE 802.3at), Type 3 (IEEE 802.3bt),
• Support for pre-standard Cisco powered devices.
• Configuration for StackPower. When the switch internal power supply module(s) cannot support the

and Cisco UPOE/UPOE+ power per port. The output of the PoE+ or Cisco UPOE/UPOE+ circuit has been
evaluated as a Limited Power Source (LPS) per IEC 60950-1.

Multigigabit Ethernet Ports

The Multigigabit (mGig) Ethernet ports can be configured to auto-negotiate multiple speeds on switch ports.
The ports support 100 Mbps, 1 Gbps, 2.5 Gbps, and 5 Gbps speeds on Category 5e (Cat5e) cables, and up to
10 Gbps over Category 6 (Cat6) and Category 6A (Cat6A) cables up to a maximum of 100 m. 10Gbps over
Cat6 cable is limited for distances up to 55 m. For 10GBASE-T, Cat6a can support up to 100 m when
transmitting 10Gbps. Due to the extra bandwidth requirements from the cable, additional limitations exist for
best performance. These limitations include, but are not limited to cable reach, cable bundling parameters
(tightness, frequency, number of cables, speed with respect to each cable) and cable termination quality.
The 802.3 channel requirements for interoperability typically limit the cable reach to 100 m, but other factors
can shorten this reach. In addition, for both Cisco UPOE and Cisco UPOE+ and data integrity, the 100 m total
should not include more than 10 m total stranded or patch cable. Therefore, it is assumed that a 100 m link
