The Drop That Went Dark

Studio B at Riverbend Drafting Co. went silent after a desk shuffle this morning. The drafter there can reach nothing on the network. Work the problem from your bench station, restore the link, and verify it.

Link status board · rb-sw-core

Each row is a switchport on rb-sw-core. An unlit indicator points to a faulty port, a faulty cable, or an unplugged cable.

Diagnostics console · rb-tech (10.27.4.30)

Available: help, ping <host|ip>, ipconfig [host], clear. The console reports agent data from managed endpoints, so you can read another host's address without leaving your bench.

Physical layer · Studio B drop

Studio B floor box → patch panel port 14 → rb-sw-core Gi0/14
Installed: Cat6 patch — jacket split at the connector (pinched under the desk leg)
