7965-S42 IBM Enterprise Slim Rack
7965-S42 IBM Enterprise Slim Rack provides an excellent 19-inch rack enclosure for any data center. The 7965-S42 IBM Enterprise Slim Rack measures 23.6 inches wide, enabling it to be easily located on standard 24-inch floor tiles and provides thermal and cable management capabilities. Compared to the IBM 7965-94Y Slim Rack, the 7965-S42 IBM Enterprise Slim Rack provides additional strength and additional shipping and installation flexibility.
The 7965-S42 IBM Enterprise Slim Rack is designed to offer great footprint efficiency for your services and systems, offering:
600 mm width to fit within a 24-inch floor tile
1100 mm rack depth for cable management space
Up to four power distribution units PDUs in rack side pockets
Optional high-efficiency Rear Door Heat Exchanger 1164-95X
Removable top 2U rack hat
Optional Rack Rear Extension 5 Inches

Standard features of the Enterprise Slim Rack include:
Front tip plate
Air dam for controlling airflow between the rack and floor
Round mounting holes following the EIA 310-D standard
Interior rail-to-rail depth of 715 mm about 28 in.
Four leveling feet
Cable egress ports on both top and bottom of rack
Due to safety considerations, the top area of the rack may not be loaded with equipment when shipped. Due to its height, special shipping and handling procedures may be required. Before shipping, IBM Manufacturing will add black snap-in front filler panels for rack space that will be unoccupied. The filler panels help control airflow and improve the rack's appearance.
The 7965-S42 IBM Enterprise Slim Rack front door, which can be Basic Black/Flat ECRM, High-End appearance ECRF, or OEM black ECRE, has perforated steel, providing ventilation, physical security, and visibility of indicator lights in the installed equipment within. It comes standard with a lock that is identical to the locks in the rear doors. The door ECRG and ECRE only can be hinged on either the left or right side. Features ECRM, ECRF, and ECRE are mutually exclusive and one of the front door features must be selected.
In the rear of the 7965-S42 IBM Slim Rack, either a perforated rear steel door ECRG or a Rear Door Heat Exchanger RDHX is used. Feature ECRG is physically identical to the feature ECRM front door except for a logo on the feature ECRM. Feature ECRG includes a lock and can be hinged on either the left or right side, depending on the needs of the client. Feature ECR2 is ordered using machine type 1164-95X for a 7965-S42 Rack. Features ECRG and ECR2 are mutually exclusive and one of the rear door features must be selected.
The RDHX indicator feature ECR2 is a no-charge code that can be used when ordering the Enterprise Slim Rack 7965-S42. Feature ECR2 ships no hardware, but indicates to IBM Configuration tools that a feature ECRG rear door is not required because a 1164-95X RDHX is going to be used. The following rules apply to feature ECR2:
If feature ECR2 is ordered on the 7965-S42 without features EDCL, EDC0, or EDCS, then 1164-95X is required with the rack order. The 1164-95X also requires feature ECR2.
If feature ECR2 is ordered with feature ECR1, then the order must have at least one air management kit ECRP.
If feature ECR2 is ordered without ECR1, then a quantity of two of feature ECRP, ECRJ, or ECRH is required.
If feature ECR2 and ECR1 are selected, then a quantity of two of feature ECRP, or a quantity of one of feature ECRP and one of feature ECRJ, or a quantity of one of feature ECRP and one of feature ECRH, is required.
Clients can select a quantity of zero, one, or two side cover features ECRJ or ECRH, these features can be mixed. Feature ECRJ is defaulted to a quantity of two. Side panels, either Rack Side Cover Black feature ECRJ or Optional Side Cover High-End Appearance for Rack feature ECRH, increase the rack's aesthetics, help control airflow through the rack, help shield against electromagnetic energy emitted by equipment in the rack, and improve security by controlling the access into the rack.
Side panels ECRJ or ECRH are optional for those clients that plan to attach one rack to another rack. Having side panels between the racks may improve airflow. However, without the side panels, routing cables between the two connected racks may be simplified or shortened by avoiding exiting the rack through top or bottom egress holes of one rack and reentering the other rack. Normal physical planning considerations must be used to ensure cables are not bent too tightly and that adequate slack exists to allow equipment to be slid forward or backward in the rack for service access. Note that although Suite Attach can improve stability, this does not meet certification tests required for earthquake-related certifications.
If you need optimized airflow with the Side/Side Attachment Kit feature ECR1, then the Airflow Management Kit feature ECRP is required in a quantity of one or two. Feature ECR1 includes hardware for rack attach.
The Slim Rack has side pockets or bays in which up to four PDUs can be vertically mounted and thus do not use the rack's Enterprise space. Two bays are located on the left rear side and two bays on the right rear side. Additional PDUs can be mounted horizontally, but then each uses 1 EIA 1U of the rack's Enterprise space.
IBM Manufacturing supports placing the following 1U PDUs in the IBM 7965-S42:
High Function 9xC19 PDU: Switched, Monitoring EPTJ
High Function 12xC13 PDU: Switched, Monitoring EPTN
Power Distribution Unit 7188
High Function 9xC19 PDU 3-Phase: Switched, Monitoring already contains a fixed line cordEPTL
High Function 12xC13 PDU 3-Phase: Switched, Monitoring already contains a fixed line cordEPTQ
In addition to the above PDUs, High-Function PDU feature EPTT offers an intelligent, switched 480/277 volt 3-phase AC Power Distribution Unit PDU with 36 Rong Feng RF 203P-M receptacles and six IEC 320-C13 receptacles on the PDU.
The PDU is mounted in the cable management space of the rack. Each pair of RF 203P-M receptacles has a 20 amp circuit breaker derated to 16 amps and all six IEC 320-C13 receptacles are fed from a single 15 amp circuit breaker derated to 12 amps.
Device power cords with RF 203-M plugs connect to RF 203P-M PDU receptacles and are ordered separately. Device power cords with IEC 320-C14 plugs connect to IEC 320-C13 PDU receptacles and are ordered separately. One wall line cord is provided with the PDU no separate feature code and has a 5-wire unterminated input. The PDU supports up to 80 amps per 277 V AC phase.
One RJ45 port in the middle of the PDU enables the client to monitor incoming electrical power usage by phase and to remotely switch on or off a pair of IEC 320-C13 receptacles. The PDU is shipped with a generic PDU password and IBM strongly urges clients to change it upon installation.
The PDU is mounted on either the left or the right side of the rack. It is tall, essentially the height of the interior of the 42U rack.
See the Limitations section for PDU placement restrictions.
If IBM Manufacturing places the PDU horizontally, then horizontal mounting brackets are included except for the tall PDU feature EPTT. PDUs that are shipped separately or preinstalled in a vertical side pocket do not come with the horizontal mounting brackets.
One PDU Access Cord 0.38m ELC0 must be used for each vertically mounted feature EPTJ or EPTN or 7188 PDU in the Slim Rack to make it easier to plug/unplug the PDU from its power source. The PDU Access cord attaches to the UTG0247 connector of the feature EPTJ, EPTN, or 7188. The power cord in PDU EPTL or EPTQ is not detachable from the PDU and thus does not need a feature ELC0.
The 5-Inch Rack Rear Extension ECRK expands the space available for cable management and may enhance airflow. The expansion is installed at the client location and is not installed by IBM Manufacturing. All rear door options are supported with the expansion.
The optional Airflow Management Kit for Rack ECRP helps ensure optimal airflow through the rack and is required when a RDHX is used. Feature ECRP in a quantity of two provides airflow management for both sides of the rack. Feature ECRP in a quantity of one provides airflow management for only one half of the rack.
The optional water cooling manifold either ECR3 or ECR4 enables water cooling of servers in the rack. Water cooling is more efficient than air cooling and greatly reduces the warm air coming from the rack equipment and may enable processors to run slightly faster. Air fans run slower, reducing noise in the machine room. The IBM Enterprise Slim Rack supports water-cooled and air-cooled systems in the same rack.
These manifolds are available for initial orders only need to be integrated in the Slim rack in manufacturing. When either feature ECR3 or ECR4 is selected, PDU vertical slots 2 and 4 will be blocked Manifold will always be on the right side as seen from the rear. Features ECR3 and ECR4 are mutually exclusive. If Water Cooling Manifold - Top Input/output for Rack ECR3 is selected, then the specify feature ER2T is required to reserve 2U space at the top of the rack. If Water Cooling Manifold - Bottom Input/output for Rack ECR4 is selected, then either the specify features ER1B or ER2B is required to reserve 1U or 2U space at the bottom of the rack. The defaulted feature is ER2B. Up to 20 water-cooled systems are allowed in a rack.
