Operations

Real operational tasks that data center engineers handle daily. Pull event logs after crashes, reconfigure BMC networking, set up serial-over-LAN for remote troubleshooting, configure hardware watchdogs, and perform security audits.

Labs in this module

Event Log - Something happened at 3 a.m. Read the server's black box: decode SEL severities with interactive diagrams, pull the 03:47 crash timeline fro
Network Config - Audit a BMC's own network identity: its address, MAC, VLAN, and how the management plane is actually wired. Read it from inside and outside
Serial Over LAN - No SSH, no monitor, no crash cart: reach a dead machine's serial console over the management network with Serial-over-LAN, then capture the
Watchdog Timer - The BMC's dead-man switch: learn how a hardware watchdog reboots a hung server all on its own, then inspect, configure, arm, evidence, and s
Security Hardening - BMCs are the most attacked door in the rack. Audit a flagged Dell BMC's users, cipher suites, LAN auth, and channel access with interactive
Memory Fault Diagnosis - A healthy-looking system rollup can still hide one failed DIMM. Diagnose a memory fault across both planes: read current component health ov
Live Fault Triage - This node reads healthy, but a job keeps dying. Watch a DIMM fail in real time across both planes: baseline DIMM.B2 as OK over Redfish, catc
