I’ve Been Here Before
Here’s the scenario: You’ve ordered a new Ethernet-delivered circuit from your ISP to connect to equipment in your cabinet at a colo facility. The carrier has dropped the circuit, the colo staff has done the cross-connect and left you a fiber pigtail in your cabinet. You’ve configured your port, inserted your SFP optical module, and plugged in the fiber. You “no shut” your port and….. nothing. Nada. Zilch. Not even a link light.
