One day, one of the DES-3200-28 B1 switches began to write the following in the logs:Continue reading “DDM Port X optic module RX power exceeded the low warning/alarm threshold”
I noticed once on the switch HP A5800 Series Switch JC103A, when inserting the module Foxgate SFP-1SM-1550nm-10SC (10km), the following error:
%Apr 26 12:18:56:384 2000 HP OPTMOD/4/MODULE_IN: GigabitEthernet1/0/24: The transceiver is UNKNOWN_SFP_PLUS. %Apr 26 12:18:56:524 2000 HP OPTMOD/5/CHKSUM_ERR: GigabitEthernet1/0/24: The checksum of transceiver information is bad! %Apr 26 12:18:56:674 2000 HP OPTMOD/3/TYPE_ERR: GigabitEthernet1/0/24: The transceiver type is not supported by port hardware!
Alternatively, you can try running the command:
But in my case this command did not help.
Also noticed that the error did not occur when inserting a similar module is not at 10km, but at 3km – Foxgate SFP-1SM-1550nm-3SC 3km.
The problem was solved by updating the firmware of the switch, as I did in the article – HP A5800 Firmware Upgrade
I updated the firmware from “A5800_5820X-CMW520-R1809P11” to “A5800_5820X-CMW520-R1810P13”.
After the upgrade, both modules were working and there were no errors in the console.
It took a couple of days ago to the Cisco Catalyst 6509-E in which there were modules only with SFP ports to connect a few links with RJ45.
Since RJ45 links are small, it was more economical to use SFP-RJ45 modules, so they were ordered.
I connected them to the ports WS-X6724-SFP, but nothing was displayed in the logs.
Let’s write commands so that Cisco does not disable ports when inserting unsupported modules:
service unsupported-transceiver no errdisable detect cause sfp-config-mismatch no errdisable detect cause gbic-invalid
I note that the ports WS-X6724-SFP in my case work only at 1Gb speed, so the link will not naturally rise to 100Mb or 10MB, although the Foxgate SFP-RJ45 modules that we had and support 10/100/1000.
In confirmation of this I checked the commands:
configure t interface gigabitEthernet 1/1 speed ?
What was the opportunity to specify the speed of the port only in 1000.
Configure Cisco Catalyst 6509-E
