IBM AS/400 7014-61R Model 670

Condition : Refurbished

The IBM 7040 Model 61R System Rack provides space for mounting system drawer components for pSeries servers such as the pSeries 690 Central Electronics Complex (7040-681) and the 7040-61D I/O drawers. The Model 61R is a 24-inch rack which provides 42U of rack space.

The 7040-61R utilizes a 350 V DC bulk power subsystem to provide power for the components within the rack. The bulk power subsystem incorporates redundant bulk power assemblies mounted in the front and rear sections of the top 8U of the rack.

Description

The 7040-61R System Rack provides space for mounting system drawer components for pSeries servers such as the pSeries 690 Central Electronics Complex (7040-681) and the 7040-61D I/O drawers. The Model 61R is a 24-inch rack which provides 42U of rack space.

The 7040-61R incorporates a 350 V DC bulk power subsystem to provide power for the components within the rack. The bulk power subsystem incorporates redundant bulk power assemblies mounted in the front and rear sections of the top 8U of the rack.

If additional 24-inch rack space is required an optional expansion rack feature is available for the Model 61R rack. The expansion rack feature connects to the side of the primary rack to provide an additional 42U of rack space. The components in the expansion rack are powered from the bulk power subsystem in the primary Model 61R rack.

7040-61R System Rack Configuration and Limitations

The 7040-61R System Rack is a 24-inch rack with an integrated power subsystem to support the pSeries servers such as the pSeries 690 (7040-681). It provides 42U of rack space.
An expansion rack feature (#8691) is available if additional 24-inch rack space is required. To install the expansion rack feature, the side cover of the 7040-61R rack is removed, the expansion rack is connected to the 61R, and the side cover is placed on the exposed side of the feature rack. Power for components in the expansion rack is provided from the bulk power assemblies in the Model 61R rack.
Over time, the 7040-61R rack will be utilized in multi-rack clusters. Rack indicators (such as #4651) will be used to identify the racks within the cluster and specify the desired rack in which to place various rack mounted components. When assigning rack indicators, the 7040-61R and its expansion rack feature #8691 are considered a single rack.
All 7040-61R racks and expansion feature racks must have door assemblies installed. The following door assemblies are available:
A sculptured black front door with copper accent (#6070) is required for the primary Model 61R rack.
A sculptured black front door (#6071) is required for the expansion rack feature, if installed.
An acoustic rear door (#6075) is available for the primary rack or the expansion feature rack. This door should be utilized for installations requiring a quieter environment.
A slim line rack door (#6074) is available for the primary or expansion rack feature. This door should be utilized for installations where system footprint is the primary consideration.
If additional external communication and storage devices are required, 7014-T00 or T42 racks should be utilized. There is no limit on the quantity of 7014 racks allowed.
The height of the 7040-61R rack (42U) or expansion feature rack may require special handling when shipping by air or when moving under a low doorway.
The 7040-61R rack always incorporates two bulk power assemblies for redundancy (#8690). These provide 350 V DC power for devices located in the 61R rack and associated expansion rack feature. These bulk power assemblies are mounted in front and rear positions and occupy the top 8U of the rack. To provide optimum system availability these bulk power assemblies should be powered from separate power sources via separate line cords.
Bulk power regulators (#6186) interface to the bulk power assemblies to ensure proper power is supplied to the systems components. The number of bulk power regulators required is dependent on the configuration of the system CEC and the number of I/O drawers installed.
Two Power Controller features (#6187) are required for all system configurations, one per bulk power assembly. Each Power Controller provides seven power connections to support system cooling fans and the attachment of system CEC and I/O drawer DC power converters. Additional connector locations are provided by the Power Distribution Assembly (#6188). Power distribution assemblies are always added in pairs (one per bulk power assembly) for redundancy. The number of power distribution assemblies required is dependent on the configuration of the System CEC and the number of I/O drawers installed.
Optional Integrated Battery Backup is available, if desired. The battery backup features protect against power line disturbances and provide sufficient power to allow an orderly system shutdown in the event that the power sources fail.
The optional Integrated Battery Backup features (#6200 and #6201) are each 2U high.
The battery backup features (if ordered) supply power to the Bulk Power Regulators (#6186) on a "one for one" basis. The Primary Battery Backup features (#6200) function with the bulk power regulators located in the bulk power assembly in the front of the rack. The Redundant Battery Backup features (#6201) function with the bulk power regulators in the bulk power assembly in the rear portion of the rack.
One Primary Battery Backup feature (#6200) is utilized for each Bulk Power Regulator (BPR) required with the front power assembly if battery backup is desired. Additional power redundancy is available by utilizing one Redundant Battery Backup feature (#6201) with each BPR for the rear power assembly.
The primary battery backup features (#6200) are mounted in the front of the rack. When two batteries are required they "stack" one above the other in the 13U through 16U positions in front of the primary system rack. These first two batteries each connect to the Bulk Power Regulators (#6186) in the "front" bulk power assembly via cable #6240. When a third Primary Battery Backup (#6200) is required it mounts in the 17-18U location in the front of the expansion rack feature (#8691). The third battery cables to the third Bulk Power Regulator in the front of the primary rack with cable feature #6241.
The Redundant Battery Backup features (#6201) are mounted in the rear of the rack. When two batteries are required they "stack" one above the other in the 13U through 16U positions in the rear of the primary system rack. They each connect to the Bulk Power Regulators (#6186) in the "rear" bulk power assembly via cable #6240. When a third Redundant Battery Backup (#6201) is required it mounts in the 17-18U location in the rear of the expansion rack feature (#8691). The third redundant battery cables to the third Bulk Power Regulator in the rear of the primary rack with cable feature #6241.
