HP ProCurve Switch xl Modules
Installing the Modules
Verifying the Network Connections Are Working
Check the port LEDs for the newly-installed module to ensure the port(s)
connected in the preceding step are operating correctly. Each port on the
switch modules has Link and Mode LEDs near it as shown in the next
illustration.
Example Link and Mode LEDs
■
If you have installed and connected an PoE xl module (J8161A), ensure
the module is receiving power from the HP 600 RPS/EPS and the PDs are
receiving PoE power from the module.
■
The Link LED will be lit for each port that is connected properly to an
active network device.
If the Link LED does not go on when an active network cable is connected
to the port, there may be something wrong with the cable, the cable
connectors, or the device at the other end of the cable. See the trouble-
shooting information on
page 26 .
■
If the switch Mode is set to display activity (the mode indicator LED
is lit), then the Mode LED for each port that is transmitting and/or
receiving packets will flicker when traffic is detected on the port.
■
If the Mode is set to display full duplex (the mode indicator LED is
lit), then the Mode LED will be lit for each port that is operating in full
duplex.
■
If the Mode is set to display maximum link speed operation (the mode
indicator LED is lit), then the Mode LED will be lit for each port that is
operating at its maximum possible link speed.
For gigabit-capable ports,
that speed would be 1000 Mbps (Gigabit); for 10/100 ports, that speed
would be 100 Mbps.
■
If the Mode is set to display packet errors on the port (the mode
indicator LED is lit), then the Mode LED will flash briefly for each packet
that has any of six errors, including CRC errors and late collisions.
