The Cisco PWR-C5-1KWAC (OEM model DPS-1000AB-5 A by Delta Electronics) is a 1000 Watt hot-swappable AC power supply designed for the Cisco Catalyst 9200 and 9300 Series switches. It provides high-efficiency power conversion and redundancy support in enterprise campus and data center environments.

This is a 1kW AC power module that delivers reliable, efficient power to Catalyst 9300 and 9200 stackable switches. It supports full PoE/PoE+ / UPOE budgets when used in pairs and features high efficiency (80 PLUS Platinum rated) with active PFC. The PWR-C5-1KWAC is hot-pluggable, allowing replacement without shutting down the switch when installed in redundant configurations.

The CX354A features two QSFP ports, each capable of operating in either 40 Gb/s Ethernet mode or 56 Gb/s FDR InfiniBand mode (40 Gb/s effective data rate with IB overhead). The VPI (Virtual Protocol Interconnect) technology allows each port to be independently configured for Ethernet or InfiniBand, providing maximum flexibility in hybrid or multi-protocol environments.
In EMC/Isilon deployments, this card was one of the most commonly used cluster interconnect NICs in Isilon H-series (hybrid) and F-series (all-flash) nodes, enabling ultra-fast node-to-node communication across the scale-out NAS cluster. It supports RDMA (Remote Direct Memory Access) over both native InfiniBand and RoCE (RDMA over Converged Ethernet), delivering near-zero CPU overhead and sub-microsecond latencies for data transfers.
The card includes extensive hardware offloads for TCP/UDP/IP stateless processing, large send offload (LSO), receive side scaling (RSS), iSCSI/SMB Direct acceleration, FCoE (Fibre Channel over Ethernet), and advanced virtualization features like SR-IOV (up to 127 virtual functions per port).

IBM 46K4939 – POWER7 80mm Fan Assembly

The IBM 46K4939 is the 80mm fan assembly (also called fan FRU) for the IBM Power 780 (machine type 9179-MHB / 9179-MHC) and some configurations of the Power 770 (9117-MMB / 9117-MMC).

This is a hot-swappable, redundant cooling fan module that provides active airflow for the Central Electronics Complex (CEC) in these high-end POWER7 servers. It is a single 80mm high-speed fan housed in a plastic tray with a latch mechanism, designed to cool the processor books, memory DIMMs, and I/O components.

In the Power 780 (and multi-book Power 770), there are multiple fan assemblies (typically 6–8 depending on configuration) working together with N+1 redundancy. The system dynamically adjusts fan speed based on thermal sensors. If one fan fails, the remaining fans increase speed to compensate, and the system raises an alert via the HMC.

The Cisco 341-0502-01, manufactured by LiteOn, is a dual-output external AC/DC power adapter that provides 53.5V at 1.55A and 12V at 3.5A through a 4-pin connector. It is commonly used to power specific Cisco routers, wireless controllers, access points, and certain service modules that require this unique voltage combination.

This compact yet powerful brick-style adapter converts standard 100-240V AC input into two regulated DC outputs (53.5V for PoE or main power and 12V for auxiliary electronics). It is an official Cisco spare part, often referenced under the alternate part number 341-100399-01. The adapter is widely used with Cisco ISR series routers, Aironet wireless controllers, and some Catalyst or ASR components that do not use standard internal 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).
