Feature Description
Forwarding Modes
Store and Forward.
Duplex Modes
Half and full duplex on all front panel ports.
Auto MDI/MDIX
Supported on all ports. If fiber SFP transceivers are used, Auto
MDIX is not supported.
Flow Control
In full duplex operation all ports are supported.
Traffic Prioritization
Four traffic queues per port.
Ethernet Ports
10/100 Mbps ports.
Each port automatically determines the speed and duplex mode of
the connected equipment and provides a suitable switched
connection. The 10/100 Mbps ports can operate in either
half-duplex or full-duplex mode.
Gigabit Combo Ports
The 2 Gigabit combo ports support fiber Gigabit Ethernet
short-wave (SX) and long-wave (LX) SFP transceivers in any
combination. This offers you the flexibility of using SFP transceivers
to provide connectivity between the Switch and a 1000 Mbps core
network.
When an SFP port is in operation, the corresponding 1000BASE-T
port is disabled. The 1000 Mbps connections can only operate in
full duplex mode.
Mounting
19-inch rack or standalone mounting.
Fanless design (supported by HP
V1905-24 Switch JD990A and HP
V1905-48 Switch JD994A)
Silent operation whether used in a rack or desktop situation.
PoE (Only supported by HP
V1905-24-PoE Switch JD992A)
Each RJ-45 port supports the IEEE 802.3af PoE standard. Any
802.3af compliant device attached to a port can directly draw
power from the switch over the Ethernet cable without requiring its
own separate power source. This capability gives network
administrators centralized power control for devices such as IP
phones and wireless access points, which translates into greater
network availability.
