Overview
Phihong’s midspans are Power over Ethernet (PoE) injectors with output options ranging from
15.4W to 95W per port. Available with 1, 2, 4, 8, 16 or 24 ports, Phihong’s midspans put out full
power every port with no need to manage power across ports.
By using the SNMPv2C (Simple Networking Management Protocol version 2C) protocol, users can
monitor and control the port status over their internet browser. Linking an Ethernet cable between
their midspan and management computer, locally or otherwise through a network switch, users
may manage certain functions including remote reset of powered devices. Users may connect to
their midspan using the DHCP client on the midspan which will create a dynamic hostname and IP
address unique to the network. Otherwise a Static IP address may be created by the user.
Internet browsers that users may choose from to access their Phihong midspans including:
Internet Explorers 7 and 8 found on Windows XP, Windows Vista and Windows 7. Mozilla Firefox,
Google Chrome, Opera and Safari may also be used. To update the firmware on your midspan,
only Microsoft XP or Vista may be used at this time. Please check www.phihong.com or www.
midspans.com for support updates or contact us at poe@phihongusa.com for additional questions
regarding compatibility. For SNMO interface, users may refer to the SNMP console manual for PC
requirements.
A default username and password come preset on your Phihong midspan. Entering “admin” in
both fields will allow users to gain access to customize their security settings. The default read-
only community string is “Phihong_read_only” and users may enter “Phihong” for the read-write
community field. Select tools that users may access through Phihong’s management interface is
port control (i.e. turn on/off), change access strings (hostname, username, password etc.), and set
IP Address to dynamic DHCP to allow it to be set automatically or Static as customized by the user.
Additionally, users may configure and send SNMPv2C TRAPs which are triggered on changes to
port status.
Phihong may release new firmware and updates at any time, so it is advised to check our websites
regularly for any updates that may affect your midspan. For the models listed on the cover page, two
firmware files are used. The first is POEA-x.x.x.bin which is uploaded to an internal microprocessor
under Windows TFTP command. The second is POEB-x.x.x.bin which is uploaded directly into an
internal EEPROM by entering http://hostmane/upload into your internet browser or by using web
<system tools>.
