NEW QUESTION # 23
How do you access the M.2 drive in the chassis?
- A. The M.2 drive is not accessible at all
- B. By removing the GPU tray from the chassis, then removing the air shroud from the GPU tray
- C. By removing the motherboard tray from the chassis, then removing the air shroud from the motherboard tray
- D. By removing the fan housing from the chassis, then removing the air shroud from the fan housing
Answer: C
Explanation:
In Supermicro systems like the SYS-421GE-TNHR2-LCC, M.2 drives are typically mounted on the motherboard for fast storage in high-performance computing (HPC) and AI workloads, often cooled indirectly by DLC systems. To access the M.2 drive, you must:
Remove the motherboard tray from the chassis: This exposes the motherboard where M.2 slots reside.
Remove the air shroud from the motherboard tray: The shroud covers components for airflow or hybrid cooling, and its removal provides access to the M.2 slot.
Option D aligns with Supermicro's design, as seen in manuals (e.g., SYS-420GP-TNAR), where M.2 drives are motherboard-mounted. A is incorrect since M.2 drives are serviceable; B (GPU tray) and C (fan housing) don't house M.2 drives in this context. Supermicro's DLC solutions prioritize motherboard accessibility, making D the correct procedure.

NEW QUESTION # 24
When replacing the air shroud onto the motherboard tray, which 2 screws should be placed back first?
- A. The first 2 screws connecting the air shroud to the fan board
- B. The first 2 screws connecting the air shroud to the fan board
- C. The first 2 screws connecting the air shroud to the PCIe tray
- D. The first 2 screws connecting the air shroud to the motherboard tray
Answer: D
Explanation:
Replacing the air shroud onto the motherboard tray in a Supermicro system involves securing it to the tray itself first for stability. The correct screws are those connecting the shroud directly to the motherboard tray, as outlined in Supermicro's assembly guides (e.g., SYS-420 series). These initial screws align and anchor the shroud, ensuring proper fitment before additional connections (if any). Options B (PCIe tray) and C/D (fan board) are incorrect since the shroud's primary attachment is to the motherboard tray, not other components.
In DLC systems, precise shroud placement enhances cooling efficiency, supporting A as the correct choice.

NEW QUESTION # 25
How many screws need to be removed in order to release the AOC card from the bracket?
- A. 0
- B. 1
- C. 2
- D. 3
Answer: D
Explanation:
An AOC (Add-On Card) in Supermicro systems, such as a NIC or GPU card, is secured to its bracket with1 screwon the metal bar at the top, a standard PCIe card mounting practice (e.g., SYS-420GP-TNAR manuals).
This single screw ensures stability while allowing easy removal, consistent with Supermicro's DLC system serviceability. 4 (A), 2 (B), or 3 (D) screws would be excessive for a single card bracket. Supermicro's modular design in DLC solutions supports C as the verified number.References:Supermicro AOC card installation guides, DLC system component specs.
NEW QUESTION # 26
What part on the motherboard tray do you need to remove first, in order to remove the air shroud?
- A. There is no support bar on the motherboard tray that prevents you from removing the air shroud
- B. The support bar at the front of the motherboard tray
- C. The support bar in the middle of the motherboard tray
- D. The support bar at the back of the motherboard tray
Answer: A
Explanation:
In Supermicro systems like the SYS-421GE-TNHR2-LCC, the air shroud on the motherboard tray is typically a lift-off component not obstructed by a support bar. Unlike some designs with structural bars, Supermicro's high-end servers (per manuals like SYS-420GP-TNAR) often feature open tray layouts for easy access, especially in DLC configurations where liquid cooling reducesreliance on complex air channels. Options A, B, and C assume a bar exists and must be removed, but no such requirement is standard. The shroud lifts off after screw removal, making D correct. Supermicro's DLC design simplifies maintenance, supporting this conclusion.References:Supermicro motherboard tray documentation, DLC system accessibility features.
NEW QUESTION # 27
What must be removed first, in order to remove the BMC cable and IO Module from the PCIe tray?
- A. The PCIe tray
- B. The AOC cage
- C. The AOM cage
- D. The BMC cage
Answer: B
Explanation:
The BMC (Baseboard Management Controller) cable and IO Module in Supermicro systems like the SYS-
421GE-TNHR2-LCC are often tied to add-on cards (AOC) within the PCIe tray. The AOC cage (likely an Add-On Card cage) must be removed first to access these components, as it houses cards and cables interfacing with the BMC. Supermicro's design (e.g., SYS-420 series) places AOC cages as sub-assemblies within the PCIe tray, requiring removal before deeper access. A (AOM cage) may be a typo or misidentification, B (BMC cage) isn't standard terminology here, and C (PCIe tray) is too broad since it's the parent assembly. D fits Supermicro's DLC service hierarchy, making it correct.

NEW QUESTION # 28
How many screws need to be removed from the internal fan to release it from the fan housing?
- A. 0
- B. 1
- C. The fan has no screws that need to be removed
- D. 2
Answer: B
Explanation:
Internal fans in Supermicro systems, including the SYS-421GE-TNHR2-LCC, are typically secured to their housing with 4 screws, a standard design for stability and ease of replacement (e.g., SYS-420 series manuals).
This allows secure mounting while facilitating serviceability, key in DLC systems where fans support hybrid cooling. 6 screws (A) is excessive, 2 (D) insufficient for stability, and C (no screws) contradicts standard fan assembly. Supermicro's DLC expertise ensures practical fan maintenance, making B the verified number.
References: Supermicro fan installation guides, DLC system cooling component specs.
NEW QUESTION # 29
Where is the screw located that releases the AOC card from the bracket?
- A. On the AOC card itself
- B. There is no screw that you need to remove
- C. On the metal bar, on the top of the bracket
- D. On the metal bar, on the top of the AOM card
Answer: C
Explanation:
In Supermicro systems, an AOC (Add-On Card), such as a NIC or GPU card, is typically secured to a bracket for stability within the PCIe tray or chassis. Based on Supermicro's hardware design for systems like the SYS-
421GE-TNHR2-LCC (a DLC-capable server), the AOC card is fastened to a metal bracket via a screw located on the metal bar at the top of the bracket. This aligns with standard PCIe card installation practices, where the bracket interfaces with the chassis, and a single screw on the bar secures it. Option A references an "AOM card" (likely a typo for AOC), but the screw isn't on the card itself. Option C is incorrect as the card doesn't self-secure, and D is false since a screw is standard. Supermicro's DLC solutions maintain traditional card mounting for compatibility, making B the correct location.References:Supermicro PCIe card installation guides, SYS-420 series documentation.
NEW QUESTION # 30
Where in the chassis are the internal fans and fan housing located?
- A. In the back of the PCIe tray
- B. In the middle of the PCIe tray
- C. In the back of the motherboard tray
- D. In the middle of the motherboard tray
Answer: D
Explanation:
In Supermicro systems like the SYS-421GE-TNHR2-LCC, internal fans and their housing are typically located in themiddle of the motherboard tray, providing airflow across CPUs and memory, even in DLC setups where liquid cooling handles primary heat removal. This placement, seen in similar systems (e.g., SYS-
420GP-TNAR), balances cooling distribution. A and B (PCIe tray) focus on GPU cooling, not motherboard fans, while C (back of motherboard tray) is less common due to PSU placement. Supermicro's DLC hybrid designs integrate fans centrally on the motherboard tray, making D correct.References:Supermicro chassis layouts, DLC hybrid cooling configurations.
NEW QUESTION # 31
When removing the PCIe tray, where are the screws located and how many screws need to be loosened?
- A. There are 4 screws that need to be loosened, two on each side of the front of the PCIe tray
- B. There are 2 screws that need to be loosened, one on each side on the sides of the GPU tray
- C. There are 6 screws that need to be loosened, three on each side on the front of the PCIe tray
- D. There are 2 screws that need to be loosened, one on each side of the front of the PCIe tray
Answer: A
Explanation:
Removing the PCIe tray in the SYS-421GE-TNHR2-LCC requires loosening4 screws, two on each side of the front, per Supermicro's standard tray removal (e.g., SYS-420GP-TNAR). This ensures secure detachment of the heavy, DLC-integrated tray. B (6 screws) is excessive, C misplaces screws to a GPU tray's sides, and D (2 screws) under-secures. Supermicro's DLC systems balance stability and serviceability, making A correct.

NEW QUESTION # 32
Which card would you most likely connect to the AOM module (AOM-GP401-PCIE)?
- A. Credit card
- B. AOM card
- C. Debit card
- D. AOC NIC card
Answer: D
Explanation:
The AOM module (AOM-GP401-PCIE) in Supermicro systems is a PCIe-based add-on module, typically for expansion cards like NICs (Network Interface Cards). The AOC NIC card (Add-On Card, Network Interface Card) is the most likely connection, as Supermicro's AOM modules (e.g., in SYS-420 series) are designed to interface with AOC cards for networking in DLC systems. A (AOM card) is vague and not a standard term, while B and D (credit/debit cards) are irrelevant. Supermicro's DLC solutions integrate high-speed networking, making C the verified choice.
