Network Ethernet cable and customer analog phone line (if used). The
network Ethernet cable, in blue, is routed from the top of rack to rack’s rear
connector. The rack connector has an internal cable to the laptop host
management console (HMC). DS8000 private network Ethernet cables (two, one
gray and one black) for another storage facility (if installed) are also located
here.

Mainline power cords. Two top exit mainline power cords for each rack,
shown in green, are routed here.
Notes:
v
Power cords are routed to the rack by the customer.
v Fibre Channel host cables are internally routed and connected by either
the customer or by an IBM service representative.
v
All remaining cables are internally routed and connected by an IBM
service representative.
Feature Codes for overhead cabling (top exit bracket)
Use the following feature code information when ordering this option.
Table 51. Feature codes for overhead cable option (top exit bracket)
Feature Code Description
1400 Top exit bracket for Fibre cable
Note:
In addition to the top exit bracket and top exit power cords, one universal ladder
(Feature code 1101) must also be purchased for a site where the top exit bracket for Fibre
cable feature is used. The universal ladder is used to ensure safe access when a DS8000
unit is serviced with a top exit bracket feature installed.
Installation and safety requirements
For example, if the cables are too long, there will not be enough room inside of the
unit to handle the extra length or they will interfere with the service process,
preventing concurrent repair. This new option has the following specifications and
limitations you must consider prior to ordering:
v In contrast to the raised-floor power cords, which have a length from the tailgate
to the connector of about 16 feet, the length of the top exit power cords are only
6 feet from the top of the unit.
v
IBM Corporate Safety restricts the servicing of your overhead equipment to a
maximum of 10 feet from the floor. Therefore, your power source must not
exceed 10 feet from the floor and must be within 5 feet of the top of the power
cord exit gate. Servicing any overhead equipment higher than 10 feet requires a
special bid contract. Contact your IBM Representative for more information on
special bids.
v
In order to meet safety regulations in servicing your overhead equipment, you
must purchase a minimum of one feature code 1101 for your top exit bracket
feature per site. This feature code provides a safety-approved 8-foot platform
ladder, which is required to service feature codes 1095, 1096, 1097, and 1400.
This provides SSRs the ability to perform power safety checks and other service
activities on the top of your unit. Without this approved ladder, IBM SSRs are
not able to install or service a unit with top cable exit features.
v To assist you with the host top exit cable routing, feature code 1400 provides a
cable channel bracket, which mounts directly below the topside of the tailgate
and its opening. Cables can be easily slid into the slots on its channels. The cable
