Cisco BLWR-RPS2300 (BLWR-RPS2300=) Full English Description

Product Overview

Important Hardware Note:

The fan module supports conditional OIR (Online Insertion and Removal). If the RPS 2300 isnot actively backing up any connected network device, technicians can hot-swap the fan module without powering off the RPS chassis. If the unit is providing backup power to switches or routers, power down the RPS 2300 before fan replacement to avoid thermal risks. Strict ESD anti-static handling procedures must be followed during maintenance. This blower module cannot be interchanged with any other Cisco switch, router or firewall fan assemblies. No reverse airflow variant is available.

Key Features

1. Intelligent Variable-Speed Thermal Regulation

   The blower dynamically adjusts rotational speed based on internal chassis temperature and operating altitude. It runs at low speed under light loads to minimize acoustic noise and power consumption, and automatically increases speed to boost airflow when internal temperatures rise. All thermal status data is monitored by the RPS 2300 embedded controller.
2. Optimized Airflow Architecture

   Airflow routing changes slightly depending on installed power supplies (750W or 1150W modules). The blower draws cool ambient air through chassis side vents across power supplies and exhausts heated air toward the rear of the RPS2300 unit. Maintain unobstructed rack ventilation space on both sides and rear of the chassis to prevent thermal hotspots.
3. Conditional OIR Support

   Hot swap is permitted only when RPS 2300 is not supplying backup power to external switches/routers. Do not leave the fan slot vacant for extended periods; prolonged operation without the blower will trigger over-temperature protection and potential hardware failure. After installation, the RPS controller automatically recognizes and validates the fan module.
4. Integrated Front Panel Management Interface

   The BLWR-RPS2300 module incorporates the complete front user interface: status LEDs for system and DC output ports, plus physical buttons to select RPS channels and toggle Active/Standby power backup modes.

• Green LED: Normal fan operation
• Amber LED: Fan fault detected
  The RPS controller generates fault alerts upon blower stall or failure.

1. Single Blower Cooling Design

   RPS2300 relies entirely on this single blower module for chassis cooling.No fan redundancyexists. Immediately arrange FRU replacement once fan fault alarms are received to avoid unplanned shutdown of the redundant power system.
2. Enterprise-Grade Reliability

   Industrial high-capacity blower engineered for 24/7 continuous operation in branch network wiring closets supporting Catalyst PoE switches and ISR routers. Suitable for mixed data, voice and video converged networking environments.
