BladeCenter JS20 specifications for NEBS/ETSI environments The following table provides a summary of the features and specifications of the BladeCenter JS20 Type 8842 in a NEBS/ETSI environment. This includes model-specific information. Microprocessor: Two IBM PowerPC® microprocessors with 512 KB ECC L2 cache Note: Use the Configuration/Setup Utility program to determine the type and speed of the microprocessors. Memory: v Four DDR PC2700 sockets v Minimum: 1 GB v Maximum: 4 or 8 GB (depends on the blade server model) * IDE devices: v NEBS application does not support internal drives Integrated functions: v One dual-port Gigabit Ethernet controller v Light path diagnostics v Local service processor v One IDE hard disk drive controller with two channels v RS-485 interface for communication with BladeCenter management module v SOL Predictive Failure Analysis (PFA) alerts: v Microprocessors v Memory Electrical input: 12 V dc Environment (NEBS): v Air temperature: - Blade server on: 5° to 40°C (41° to 104°F). Altitude: -60 to 1800 m (-197 to 6000 ft) - Blade server on (short term): -5° to 55°C (23° to 131°F) Altitude: -60 to 1800 m (-197 to 6000 ft) - Blade server on: 5° to 30°C (41° to 86°F). Altitude: 1800 to 4000 m (6000 to 13 000 ft) - Blade server on (short term): -5° to 45°C (23° to 113°F). Altitude: 1800 to 4000 m (6000 to 13 000 ft) - Blade server off: -40° to 70°C (-40° to 158°F) v Humidity: - Blade server on: 5% to 80% - Blade server on (short term): 5% to 90% but not to exceed 0.024 kg water/kg of dry air - Blade server off: uncontrolled Size: v Height: 24.5 cm (9.7 inches) v Depth: 44.6 cm (17.6 inches) v Width: 2.9 cm (1.14 inches) v Maximum weight: 5.4 kg (12 lb) Notes: 1. The operating system in the blade server must provide USB support for the blade server to recognize and use the CD drive and an external diskette drive. The BladeCenter T unit uses USB for internal communication with these devices. 2. Processor power reduction methods might be invoked in the upper portion of the NEBS short term extended range. This condition is indicated by event log messages. Do not restart the blade server when power reduction is in effect. Chapter 1. Introduction 7
