Mounting cable guides and routing cables
Because of the different maximum cable lengths in single-ended and differential-ended SCSI mode,
two types of cable routing are possible in the rack: limited and unlimited cable routing.
Unlimited cable routing
A maximum cable length of 20 m is possible for differential-ended SCSI operation. With this the
SCSI cables can be routed without restriction in the cable chain. The slide-in modules can thus be
pulled out later without any further preparations.
When mounting the cable routing using a cable chain, proceed as follows:
Ê
Lay the cables inside (1) and outside (2) in die cable chain. Make sure that sufficient cable
length is available for each cable on the slide-in module side for connection to the server.
Ê
Secure the cables on the cable chain termination (a) with cable ties.
Ê
Route the cable chain equipped with the cables into the cable tray.
When you add cables to an already existent installation, then pull the server completely

out of the rack (see
then possible without detaching the cable chain from the cable tray. However, if cables
are added in the outside chain, the cable chain must be detached from the cable tray and
pulled out completely.
