| RJ-45 Ports | 48 x Gigabit Ethernet |
Combo Ports (RJ45 + Small form-factor
pluggable [SFP]) | 4 x SFP |
| Packet Buffer | 3 MB |
| Unit dimensions (W x D x H) | 445 x 350 x 44 mm (17.5 x 13.78 x 1.73 in) |
| Layer 3 |
| IPv4 routing | Wirespeed routing of IPv4 packets
Up to 990 static routes and up to 128 IP interfaces |
| IPv6 routing | Wirespeed routing of IPv6 packets |
| Layer 3 Interface | Configuration of Layer 3 interface on physical port, Link Aggregation (LAG),
VLAN interface, or loopback interface |
| Classless Interdomain Routing (CIDR) | Support for classless interdomain routing |
| RIP v2 | Support for Routing Information Protocol version 2 for dynamic routing |
| Policy-Based Routing (PBR) | Flexible routing control to direct packets to different next hop based on
IPv4 or IPv6 Access Control List (ACL) |
| DHCP Server | Switch functions as an IPv4 DHCP server serving IP addresses for
multiple DHCP pools/scopes
Support for DHCP options |
| DHCP relay at Layer 3 | Relay of DHCP traffic across IP domains |
| User Datagram Protocol (UDP) relay | Relay of broadcast information across Layer 3 domains for application
discovery or relaying of Bootstrap Protocol (BOOTP)/DHCP packets |
| Quality of Service |
| Priority levels | 8 hardware queues |
| Scheduling | Strict priority and Weighted Round-Robin (WRR) |
| Rate limiting | Ingress policer; egress shaping and rate control; per VLAN, per port,
and flow based; 2R3C policing |
| Congestion avoidance | A TCP congestion avoidance algorithm is required to minimize and
prevent global TCP loss synchronization |
| iSCSI traffic optimization | A mechanism for giving priority to iSCSI traffic over other types of traffic |
| Green (power efficiency) |
| Energy Detect | Automatically turns power off on RJ-45 port when detecting link down.
Active mode is resumed without loss of any packets when the switch
detects the link up |
| Cable length detection | Adjusts the signal strength based on the cable length. Reduces the power
consumption for shorter cables. |
| EEE Compliant (802.3az) | Supports IEEE 802.3az on all copper Gigabit Ethernet ports |
| Disable port LEDs | LEDs can be manually turned off to save on energy |
| Time-based port operation | Link up or down based on user-defined schedule
(when the port is administratively up) |
| Time-based PoE | PoE power can be on or off based on user-defined schedule
to save energy |
| General |
| Jumbo frames | Frame sizes up to 9K bytes. The default MTU is 2K bytes |
| MAC table | 16K addresses |
| Hardware |
| USB slot | USB Type-A slot on the front panel of the switch for easy file and
image management |

1000BASE-T |
| LEDs | System, Link/Act, PoE, Speed |
| Flash | 256 MB |
