The IBM 11S45D75 is the Evaporator Assembly (refrigerated / liquid-cooled heatsink) for high-end IBM zEnterprise systems, primarily the zEnterprise 196 (z196) and zEnterprise 114 (z114) in liquid-cooled configurations.

Product Description

This is a specialized liquid-cooled cold plate and evaporator unit that mounts directly onto the high-power Multi-Chip Modules (MCMs) in the Central Electronics Complex (CEC). It uses chilled liquid (typically facility chilled water or a dedicated cooling loop) to efficiently absorb and remove heat from the processors, providing significantly better thermal performance than traditional air-cooled heatsinks.

In liquid-cooled zEnterprise setups, multiple evaporator assemblies are installed (one per processor book/MCM). The assembly includes:

• Integrated cold plate/evaporator with internal liquid channels
• Quick-connect fittings for the chilled water loop
• Temperature sensors and leak detection circuitry
• Precision mounting hardware and thermal interface material

This component is critical for maintaining safe operating temperatures in dense, high-TDP z196/z114 systems. Failure or leakage can trigger thermal alerts, processor de-configuration, throttling, or protective system shutdown.

Replacement is a major service action that usually requires powering down the CEC and trained IBM service personnel due to the liquid cooling loop.

Product Description

This is a specialized water/liquid-cooled cold plate and evaporator unit that mounts directly onto the high-power Multi-Chip Modules (MCMs) in the Central Electronics Complex (CEC). It uses chilled liquid (facility chilled water or a dedicated cooling loop) to efficiently remove heat from the processors, providing far superior thermal performance compared to traditional air-cooled heatsinks.

In liquid-cooled zEnterprise configurations, multiple evaporator assemblies are used (one per processor book/MCM). The assembly includes:

• Integrated cold plate/evaporator with internal liquid channels
• Quick-connect fittings for the chilled water loop

The IBM 01LJ126 is a hot-swap fan module (also listed as fan FRU or cooling module) designed specifically for the IBM Storwize V5000 Gen2 storage systems, particularly the 92F model (24-bay 2.5-inch SFF enclosure) and related expansion units in the V5000 Gen2 family.

This is a high-speed, redundant fan assembly that provides active cooling for the Storwize V5000 Gen2 controller enclosure or expansion enclosure (92F = 2.5" SFF 24-drive canister). The module contains multiple high-RPM fans arranged in a single replaceable tray, with integrated airflow direction optimized for front-to-back cooling in the enclosure.

Key characteristics:

• Hot-swappable design — can be replaced without powering down the enclosure when redundancy is maintained (N+1 fan redundancy typical in V5000 Gen2)
• Built-in fault detection and reporting to the Storwize firmware (via LED status and system alerts in GUI/CLI)
• Tool-less insertion/removal with latch mechanism
• Front-to-back airflow (cold aisle intake, hot aisle exhaust)
• Low acoustic noise profile for data center environments

Failure of a fan module typically triggers:

• Amber fault LED on the module
• Enclosure fault light
• Critical alert in Storwize GUI / CLI / email / SNMP
• Potential thermal throttling or enclosure shutdown if multiple fans fail

Replacement restores full cooling redundancy and prevents overheating of drives, controllers, or cache batteries.

The IBM 01LJ138 is the official hot-swap drive caddy (also called LFF hard drive tray, carrier, or sled) for 3.5-inch Large Form Factor (LFF) drives in the IBM Storwize V7000 Gen2 (models 2076-524/624/724) and Storwize V9000 systems (and compatible expansion enclosures).

This is a tool-less, hot-swappable drive tray designed to securely hold and mount standard 3.5-inch SAS/SATA HDDs or SSDs into the Storwize V7000 Gen2 or V9000 front drive bays. It features:

• Black plastic/metal construction with a spring-loaded latch
• ESD (electrostatic discharge) protection
• Vibration-dampening mounts to reduce drive wear in dense enclosures
• LED pass-through for drive activity/fault indicators
• Alignment pins/guides for fool-proof insertion into the backplane

The caddy is mandatory for installing or replacing drives in these systems — bare drives cannot be inserted directly. It is the exact same tray used in most IBM Storwize V7000 Gen2 and V9000 enclosures (24-bay LFF or 12-bay LFF configurations).

Failure to use the correct tray (or using a mismatched tray from V7000 Gen1, V5000, or other vendors) can cause:

• Drive not detected
• Backplane connection failure
• Vibration-induced errors
• Improper seating or ejection

This tray is a very common FRU (Field Replaceable Unit) when trays are lost, damaged, cracked, or worn out during drive replacements.

The IBM 01EM868 is the official side rail kit (also known as rack mounting rails or slide rails) designed specifically for the IBM Power System IC922 (machine type 8335-GTG / 8335-GTH), a high-performance 2U rack server from the POWER9 generation (launched 2018–2019).

This is a tool-less, full-extension sliding rail kit that allows the IBM Power IC922 server to be securely mounted in a standard 19-inch EIA-310 rack while providing smooth, full server pull-out for easy servicing, cabling, component replacement, or upgrades without removing the server from the rack.

The kit consists of:

• Left and right telescoping rails
• Quick-release latches
• Tool-less snap-in mounting points (for square-hole racks)
• Included hardware for round-hole/threaded racks (cage nuts, screws, adapters)
• Installation instructions

It is adjustable to fit a wide range of rack depths (typically ~631–868 mm / 24.8–34.2 inches), making it compatible with most standard 19-inch racks (Dell, HPE, APC, Rittal, etc.). The rails support front-to-back or back-to-front airflow configurations and include safety stops to prevent accidental full removal.

This rail kit is essential for proper racking of the IC922 — it is the IBM-validated solution that ensures mechanical stability, proper alignment with the chassis, and compliance with IBM rack-mount specifications (especially important for heavy 2U POWER9 servers with multiple GPUs, large memory, or high-power PSUs).

The IBM 00E6367 (also listed with CCIN 2BF8 and alternate part 00RR726) is a Processor Voltage Regulator Module (VRM) specifically designed as VRM-PROC2-CJ — a power regulation subassembly for the processor book (CPU complex) in high-end IBM Power Systems servers.

This is a DC-DC voltage regulator module that steps down bulk power from the server's main power supplies to precise, stable low-voltage rails required by POWER7 processors and associated memory/cache subsystems in the CEC (Central Electronics Complex). It is part of the PROC2 (Processor 2) voltage regulation group — one of several VRMs per processor book that work in parallel to deliver high current with redundancy and load sharing.

In high-end IBM Power Systems, each processor book (also called processor card or CPU book) contains multiple VRMs to support multi-core POWER7 SCMs (Single-Chip Modules) and large memory configurations. The 00E6367 / VRM-PROC2-CJ is a critical component in the power distribution chain — failure of this module can cause:

• Processor throttling or clock-down
• Voltage instability
• System crashes or boot failures
• Reduced performance under load
• Redundancy loss (N+1 or N+N configuration)

The module includes integrated protection (over-current, over-voltage, over-temperature), monitoring circuitry, and status LEDs. It is hot-swappable in redundant setups (when other VRMs can compensate) and is monitored via the Hardware Management Console (HMC) and ASMI (Advanced System Management Interface).
