Combo Ports (RJ45 + Small form-
factor pluggable [SFP]) | 2 x Gigabit Ethernet combo |
| Packet Buffer | 1.5 MB |
| Unit dimensions (W x D x H) | 268 x 185 x 44 mm (10.56 x 7.28 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 |
| Buttons | Reset button |
| Cabling type | Unshielded Twisted Pair (UTP) Category 5e or better for 1000BASE-T |
| LEDs | System, Link/Act, PoE, Speed |
| Flash | 256 MB |
| CPU | 800 MHz ARM |
| DRAM | 512 MB |
| Environmental |
| Storage temperature | -13° to 158°F (-25° to 70°C) |
| Operating humidity | 10% to 90%, relative, noncondensing |
| Storage humidity | 10% to 90%, relative, noncondensing |
| Warranty | Limited lifetime with next business day advance replacement (where available) |
