Pantel, Cisco, or Linksys PoE endpoints all work on the Dell Powerconnect 3524P.
A user tried hard coding the switch speed/duplex and tried four different Dell Powerconnect 3524P switches.
--- Check to make sure the Dell Powerconnect 3524P has flow control enabled on the port for the Guardian
device to power up properly.
According to Dell:
Flow Control Support (IEEE 802.3X)
: Flow control enables lower speed devices to communicate with higher
speed devices by requesting that the higher speed device refrain from sending packets. Transmissions are
temporarily halted to prevent buffer overflows. For information on configuring Flow Control for ports or LAGs,
see "
Defining Port Configuration
" or "
Defining LAG Parameters
" in the
Dell™ PowerConnect™ 35xx
Systems User's Guide
.
15. I am unable to connect with the unit when it is plugged into a Cisco SLM 224P switch.
The cables or switch ports that you are connecting to are set in
switch
or
hub mode
instead of
endpoint
stations
. The
MDIX
setting needs to be changed to
MDI
since Guardian VoIP products are end stations.
From the Cisco SLM 224P User Guide:
Change to MDI:
MDI / MDIX
Displays the Media Dependent Interface (MDI) / Media Dependent Interface with Crossover
(MDIX) status on the port. Hubs and switches are deliberately wired the opposite of the way end stations are
wired, so that when a hub or switch is connected to an end station, a straight through Ethernet cable can be
used, and the pairs are matched up properly. When two hubs or switches are connected to each other, or two
end stations are connected to each other, a crossover cable is used to ensure that the correct pairs are
connected. The possible field values are: -
MDIX
Use for hubs and switches. -
MDI
Use for end stations.
16. I have a Cisco 6513 switch. When I plug in a Guardian VoIP device, the device constantly reboots and
will not register to the SIP server.
Adjust the switch power selection to
Power inline static
, as opposed to
Power inline dynamic
. This will
allow the device to continuously receive 15.4W of power.
17. We have registered the device on Cisco Call Manager but are unable to register the device's
Nightringer using the device's MAC address. How do I configure two extensions on Call Manager for
the device?
Create a second directory number and user for the Nightringer extension. You may need to fudge a digit of
the MAC Address so that Call Manager allows you to associate it to the new user. Be sure this MAC address
does not match any other Guardian devices on your network.
