Installing a Stand-alone Server in a Cabinet Air flow Service Access Cable strain relief rp24xx servers require front-to-back airflow. Therefore, a solid front or rear door will not work. The doors must be removed or changed to a 63% open perforation pattern over an area 17 inches wide, top to bottom, minus a 2 inch border. Also insure that the hot air exhaust from other equipment is not being presented to the intake (front) of the rp24xx server. To insure that the rp24xx server can be serviced properly, the installation must allow for a free sliding distance of 40 inches out the front of the rack. This will also allow HP to use the standard service contract for any rp24xx server in the field regardless of the racking situation. Alternate service contracts are addressed later in this document. The cable management solution for the rp24xx server is in two parts: 1. There is a wire-form cable management system that attaches to the rear of the server that provides a strain relief attachment point. 2. The cable bundle from each server must be Velcro tie-wrapped and fed into a 40 inch service loop. The service loop allows the server to slide forward completely out of the rack for access. For warranty purposes, a proper method of strain relief must be used, especially for any SCSI-type cables on the PCI cards. This may force the elimination of the rear door in some cases. Judgement is required based on the following examples: • MINIMAL CABLING- If the customer has a power cable and two LAN cables attached to the rp24xx server, cabling options include an alternate strain relief system, to allow the rear door (if perforated) to be used for security. • FIBER OPTICS CABLING - Fiber optics cable allows a 1.5 inch bend radius and has a very low profile connector. Fiber optics cable bundles are relatively small and can be held to the inside of the wire-form strain relief. • MAXIMUM SCSI CABLING - If ultra-flex SCSI cables are used, the bend radius allowable is 1.5 inches with a low profile connector. the customer must use the provided wire form strain relief parts.

Installing a Stand-alone Server in a Cabinet
86
Air flow
rp24xx servers require front-to-back airflow.
Therefore, a solid front or rear door will not
work.
The doors must be removed or changed to a 63% open perforation pattern over an
area 17 inches wide, top to bottom, minus a 2 inch border.
Also insure that the hot air
exhaust from other equipment is not being presented to the intake (front) of the rp24xx
server.
Service Access
To insure that the rp24xx server can be serviced properly, the installation must allow for a
free sliding distance of 40 inches out the front of the rack. This will also allow HP to use the
standard service contract for any rp24xx server in the field regardless of the racking
situation.
Alternate service contracts are addressed later in this document.
Cable strain
relief
The cable management solution for the rp24xx server is in two parts:
1. There is a wire-form cable management system that attaches to the rear of the server
that provides a strain relief attachment point.
2. The cable bundle from each server must be Velcro tie-wrapped and fed into a 40 inch
service loop.
The service loop allows the server to slide forward completely out of the
rack for access.
For warranty purposes, a proper method of strain relief must be used,
especially for any SCSI-type cables on the PCI cards.
This may force the elimination of
the rear door in some cases.
Judgement is required based on the following examples:
•
MINIMAL CABLING- If the customer has a power cable and two LAN cables attached
to the rp24xx server, cabling options include an alternate strain relief system, to allow
the rear door (if perforated) to be used for security.
•
FIBER OPTICS CABLING – Fiber optics cable allows a 1.5 inch bend radius and has a
very low profile connector. Fiber optics cable bundles are relatively small and can be
held to the inside of the wire-form strain relief.
•
MAXIMUM SCSI CABLING – If ultra-flex SCSI cables are used, the bend radius
allowable is 1.5 inches with a low profile connector. the customer must use the provided
wire form strain relief parts. HP strongly recommends using a server rack that provides
the extra space required to house excess cabling.
rp24xx server PDU Support
PDUs for rp24xx servers must be ordered as separate products when configuring a Third Party Rack order.
The PDUs are:
