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>.
