Installing an SFP module and fibre channel cable
Statement 3:
DANGER: Some laser products contain an embedded Class 3A or Class 3B laser diode. Note the
following: Laser radiation when open. Do not stare into the beam, do not view directly with optical
instruments, and avoid direct exposure to the beam.
All host and drive cabling connections require you to use Small Form-Factor Pluggable (SFP) modules in
the DS4500 host and drive channels used by the cabling connections. The SFP module housing and fibre
channel cable have integrated guide keys that prevent you from inserting these devices incorrectly. You
must insert SFP modules into ports with minimal pressure so that you do not damage either the SFP
module or the port. You can insert an SFP module into an active port without affecting the operational
loop performance. You must connect the fibre channel cable to the SFP module after you insert the SFP
module into the port.
Attention: Remove SFP modules from any unused mini hub ports (both host-side and drive-side) on the
DS4500 Storage Subsystem.
To avoid damage to your fibre-optic cables:
v
Do not route the cable along a folding cable-management arm.
v Route the cable away from places where it can be damaged by other devices in the rack cabinet.
v
For devices on slide rails, leave enough slack in the cable so that it does not bend to a diameter of less
than 76 mm (3 in.) or a radius less than 38 mm (1.5 in.) when extended or become pinched when
retracted.
v Do not use plastic cable ties in place of the provided cable straps.
v
Do not put excess weight on the cable at the connection point. Be sure that the cable is well supported.
1. Remove the protective caps from the SFP module and from the fibre channel cable. Do not touch the
exposed fibre-optic cable.
