First Power-On

Power-on sequence and initial system verification.

⏱️ Time Required: 10-15 minutes


Before Powering On

Verify pre-power checklist:

  • EDC positioned with adequate clearance (rear: 6+ inches, front: 24+ inches)
  • Support legs deployed and stable
  • Both lids removed (front and rear - required for operation)
  • Power cable ready (from accessory kit)
  • Power cable NOT YET connected to EDC or wall outlet
  • No shipping restraints remain installed
  • Environmental conditions acceptable (15-30°C / 59-86°F)

⚠️ Why both lids must be removed:

  • Rear lid: Required for power cable access to PDU
  • Front lid: Required for airflow to internal components (prevents overheating)
  • Never operate with lids closed - critical for cooling and access

Optional - Network uplink:

  • Uplink cable NOT connected for initial power-on (prevents DHCP conflicts)
  • Will connect uplink after initial verification

Note: We'll connect the power cable as part of the power-on sequence below.


Power-On Sequence

Step 1: Connect Power Cable

What will happen: When you plug in the power cable, the PDU will boot automatically and begin powering the system components.

  1. Locate the PDU on the rear panel

    • PDU is mounted on the bottom of the rear panel
    • Power inlet is on the left side of the PDU
  2. Plug the power cable into the PDU

    • Take the included power cable
    • Insert the IEC C13 connector into the PDU power inlet
    • Push firmly until fully seated
  3. Plug the other end into the wall outlet

    • Use a grounded 3-prong outlet
    • North America: 110-120V outlet
    • International: 220-240V outlet
  4. Verify PDU powers on

    • PDU LCD display should light up within 2-3 seconds
    • Display shows voltage and power consumption
    • Initial reading will be low (only PDU and switch powered initially)

Step 2: Verify Switch Power-On

The EnGenius switch should power on automatically when main power is enabled.

Verification:

  • Look for LED indicators on the switch
  • Power LED should be solid green
  • Port LEDs will illuminate as devices connect
  • May take 30-60 seconds for full boot

Normal behavior:

  • Switch boots and runs self-test
  • Some LEDs may flash during startup
  • Port LEDs light as internal devices connect

Step 3: Verify IoT Device Power-On

The IoT monitoring device is powered via PoE from the switch.

Verification:

  • IoT device should power on automatically
  • May take 1-2 minutes for full boot
  • Device-specific indicators (LEDs or display) should activate

Note: Specific IoT device details vary - refer to included documentation for your model


Step 4: Power On Compute Nodes

Compute nodes require manual power-on. The process differs by edition.


Edition-Specific Power-On Procedures

📦 NUC Edition

Node power-on:

  1. Open front panel to access compute drawer

    • NUC nodes are visible in the compute drawer
    • Each NUC has a power button on the front
  2. Power on nodes in sequence

    • Start with Node 1 (leftmost)
    • Press and release power button
    • Wait 10-15 seconds
    • Power on Node 2 (center)
    • Wait 10-15 seconds
    • Power on Node 3 (rightmost)

Boot indicators:

  • Intel logo/splash screen on connected display (if attached)
  • Power LED on each NUC (solid when running)
  • Fan noise from each node
  • Network activity LEDs on rear of NUCs

Boot time: 30-90 seconds to reach operating system

Expected behavior:

  • NUCs boot to installed HCI operating system
  • HCI software starts automatically
  • Nodes become accessible via network

🔶 HR01-2 Edition

Node power-on:

  1. Open front panel to access compute drawer

    • Two HR-01 server nodes visible
    • Power buttons on front of each node
  2. Power on nodes in sequence

    • Node 1 (left) first
    • Press and release power button
    • Wait 15-20 seconds
    • Node 2 (right)
    • Press and release power button

Boot indicators:

  • Power LED on front panel of each node
  • Fan speed increases during POST
  • Network link LEDs on rear network ports
  • Display output (if monitor attached)

Boot time: 60-120 seconds to reach operating system

Expected behavior:

  • Nodes complete POST (Power-On Self Test)
  • Boot to installed HCI operating system
  • Fan speeds may be higher initially, then stabilize
  • HCI software starts automatically

🔷 HR01-4 Edition

Status: Coming Soon

Placeholder for HR01-4 specific power-on procedures.


Initial Power-On Verification

PDU Display Check

Look at the PDU LCD display:

  • Voltage: Should show 100-120V (NA) or 200-240V (International)
  • Current: Will increase as nodes boot
  • Power: Total system power consumption

Typical readings after full power-on:

  • NUC Edition: 200-400W
  • HR01-2 Edition: 300-600W
  • HR01-4 Edition: 500-900W (estimated)

If voltage reading is incorrect:

  • Verify correct input voltage at outlet
  • Check power cable connections
  • See troubleshooting section below

Switch Status Check

Check the switch LED indicators:

  • Power LED: Solid green
  • Port LEDs:
    • Ports 1-6 (NUC) or 1-4 (HR01-2): Should show link activity
    • Port 7 (PDU): Solid or blinking (network activity)
    • Port 8 (IoT): Solid or blinking
    • Ports 9-10 (Uplink): Dark (no uplink connected yet)

Cooling System Check

Listen for fan operation:

  • Cooling fans should be audible from rear of EDC
  • Initial fan speed may be higher during boot
  • Fan speed should stabilize after 2-3 minutes
  • Airflow should be felt at rear exhaust vents

Feel rear exhaust:

  • Place hand near rear panel vents
  • Should feel slight airflow
  • Air will warm up as system runs

If no fan noise or airflow:

  • See troubleshooting section
  • Do not continue operation without cooling

Compute Node Verification

For each compute node:

  • Power LED lit (indicates node is running)
  • Network activity LEDs blinking on node network ports
  • Fan noise from each node
  • No error beeps or alarm sounds

Boot time expectations:

  • NUC Edition: 30-90 seconds to OS
  • HR01-2 Edition: 60-120 seconds to OS

HCI software startup:

  • May take additional 2-5 minutes after OS boots
  • Nodes will join cluster automatically
  • Access via HCI management interface (see next steps)

Normal First Boot Behavior

What you should observe:

  1. PDU powers on immediately (2-3 seconds)
  2. Switch boots (30-60 seconds)
  3. IoT device powers on via PoE (1-2 minutes)
  4. Compute nodes boot when powered on (30-120 seconds per node)
  5. System becomes stable within 5-10 minutes total

Normal sounds:

  • Fan noise (varies by cooling profile)
  • Brief hard drive seeking sounds (if HDDs present - unlikely in NVMe configs)
  • No beeping, clicking, or alarm sounds

Normal temperature progression:

  • System starts cool
  • Temperature rises during first 10-15 minutes
  • Fans may increase speed temporarily
  • System stabilizes at normal operating temperature

Troubleshooting

Nothing powers on - no PDU display

Problem: No power to any component

Check:

  1. Power cable fully inserted at both ends (PDU inlet and wall outlet)
  2. Wall outlet has power (test with another device)
  3. Circuit breaker not tripped
  4. Extension cord or power strip functioning (if used)
  5. PDU inlet connection is secure

If still no power:

  • Contact your reseller immediately
  • Do not attempt internal inspection
  • May be PDU or wiring issue
PDU powers on but switch does not

Problem: PDU LCD lit but switch has no LEDs

Check:

  1. Wait 60 seconds - switch may still be booting
  2. Look carefully at switch - some LEDs are small
  3. Check internal power connection from PDU to switch (if qualified)

If switch does not power on after 2 minutes:

  • Contact your reseller
  • Switch may require service
  • Possible internal cable issue
Compute nodes won't power on

Problem: Pressing power button has no effect

Check:

  1. Verify PDU is powered on (LCD lit)
  2. Check power cable connection to each node
  3. Try holding power button for 2-3 seconds
  4. Look for error LEDs on node front panel

If nodes still won't power on:

  • Verify outlet power cycling hasn't disabled PDU outlets
  • Check PDU display for outlet status
  • Contact reseller if issue persists
Fans running very loud / not running

Problem: Fan noise excessive or absent

Fans very loud:

  • May be normal during initial boot (high speed startup)
  • Should stabilize within 3-5 minutes
  • If remains loud, may be set to Turbo profile
  • See Cooling Management

No fan noise:

  • Eco profile may be very quiet at low temps
  • Place hand at rear exhaust to verify airflow
  • If NO airflow at all - contact reseller immediately
  • Do not continue operation without cooling
Beeping or alarm sounds

Problem: System making beeping or alarm sounds

Possible causes:

  • Component error during POST
  • Overheating (unlikely during initial power-on)
  • Hardware failure

Actions:

  1. Note the beep pattern (count beeps, note pauses)
  2. Check which component is beeping (node, PDU, etc.)
  3. Power off immediately if continuous alarm
  4. Contact reseller with beep pattern information
  5. Do not continue operation with error alarms
High power consumption reading

Problem: PDU shows unexpectedly high power draw

Check:

  1. Verify reading is in watts (not amps or volts)
  2. Compare to expected range for your edition
  3. Ensure no additional devices connected

If power consumption seems excessive:

  • May indicate issue with compute nodes or components
  • Document the reading
  • Contact reseller for guidance

Safety - When to Power Off Immediately

Power off the system immediately if you observe:

  • ⚠️ Smoke or burning smell
  • ⚠️ Sparks or electrical arcing
  • ⚠️ Continuous loud beeping/alarms
  • ⚠️ No cooling fan operation at all
  • ⚠️ Extremely hot surfaces (too hot to touch)
  • ⚠️ Liquid leakage
  • ⚠️ Unusual loud mechanical noise (grinding, clicking)

Emergency shutdown procedure:

  1. Unplug the power cable from the PDU immediately (if safe to do so)
  2. If unsafe to approach the rear panel, unplug from the wall outlet instead
  3. Contact reseller immediately
  4. Do not attempt to restart
  5. Document what you observed
