Attention: It is important to wait a minimum of 10 seconds between the removal
and insertion of a line module. Re-insertion of a line module less than 10 seconds
after the removal of a line module may result in the line module not being properly
recognized.
See “Replacing an interface module” on page 97 for instructions.
24-port 10/100/1000 Mbps Ethernet RJ45 copper interface module
The 24-port 10/100/1000 Mbps Ethernet RJ45 copper interface module has
twenty-four 10/100/1000 ports with RJ-45 connectors for Cat5 cabling. The copper
ports support automatic MDI/MDIX detection, and use auto-sensing and
auto-negotiating to determine the speed (10, 100, or 1000 Mbps) and duplex mode
(full-duplex or half-duplex) of the port at the other end of the link, and adjust the
port accordingly. Ports operating at 1000 Mbps operate in the full-duplex mode only
and cannot be modified.
This interface module supports Power over Ethernet (POE). You can order an
upgrade kit for your 24-port 10/100/1000 Mbps Ethernet RJ45 copper interface
module that includes a POE daughter card that is installed onto the module. To run
POE on your system, at least one 48-volt POE power supply must also be installed
in the chassis. See “Installing or replacing a POE daughter card” on page 102.
Figure 8 shows the front panel of the IPv4 24-port Gigabit Ethernet copper module.
The IPv6 24-port Gigabit Ethernet copper looks identical except for the 624C label
on the left edge.
The front panel includes the following control features:
v
24 10/100/1000 copper ports
v 24 LEDs for port status
v
24 LEDs for Power over Ethernet (POE) status
Note: The POE LEDs work only when POE is enabled on your device.
LEDs for 24-port 10/100/1000 Mbps Ethernet RJ45 copper
interface module
The front panel of the 24-port Gigabit Ethernet copper module includes 24 LEDs
that indicate the status of each port, and 24 LEDs (on bottom) that indicate the
status of POE.
Note: The POE LEDs work only when POE is enabled on your device.
The copper ports also provide status information using the LEDs.
