Hot Swappable IP I/O Boards and SFPs
Hot Swappable IP I/O Boards and SFPs
IP I/O boards are hot swappable. SFPs are also hot swappable on each board, provided the
SFP modules are all of the same (supported) type. Swapping an SFP module on a board
requires that the new module be identical to the one being replaced.
Troubleshooting
When the Frame IP Address is entered into a browser, the IP SFP Statistics web page
provides useful data for determining if the bandwidth for an SFP has been exceeded in
relation to the image format speed (Gb/s), Board SFP Speed (Gb/s), and Streams/SFPs mode
selected (e.g. 4 inputs/2 outputs, 8 inputs, 2 outputs).
Additionally, it can be determined if an SFP is passing video; if an SFP is configured and the
Gb/s throughput column displays a number lower than the configured SFP speed, there
may be an issue with the SFP module or the bandwidth has been exceeded.
Open the GV K-Frame Web Access pages by entering the Frame IP Address into a browser
on the system network and selecting IP SFP Statistics on the left.
Note: The Phy Link/Lock Status column (far right) in the SFP Statistics
Web Access page, provides Ethernet link status. If the status is “Up”, the
Ethernet link is up and locked, the speed is matched between the
switcher and the external device, and it is working properly. If the status
is “Down”, there is either an issue with the link connection or a mis-match
of Ethernet link speed.
In the example following, the SFP Stream mode type is 8 inputs/4 outputs and the Rx
Throughput is over 10Gb/s, requiring a 25Gb/s SFP IP board configuration. The image
format speed coupled with the 8/4 mode selection requires 25Gb/s of bandwidth. The Link
Speed (Gb/s) column (second from the right) shows that the IP board SFPs are configured as
25Gb/s.
CAUTION: Exceeding the SFP bandwidth will result in a signal loss for
the associated SFP ports.
