Installing SFPs and attaching cables

The 64-bit chassis ID is required to obtain and activate licenses for the PowerConnect B-DCX-4S.
The chassis ID is available through the licenseIdShow command. The licenseShow and
licenseIdShow commands must be entered on the active CP blade. Refer to the Fabric OS
Administrator's Guide for more information.

Installing SFPs and attaching cables

Follow these steps to install SFPs (or XFPs with an FC10-6 port card installed) and cables to the
PowerConnect B-DCX-4S.
The ports are color-coded to indicate which can be used in the same port group for trunking
(trunking port groups can be up to eight ports). The ports and cables used in trunking groups must
meet specific requirements. Refer to the Fabric OS Administrator's Guide for more information.
1. Position one of the optical transceivers so that the key is oriented correctly to the port. Insert
2. Position a cable so that the key (the ridge on one side of the cable connector) is aligned with

Managing cables

ATTENTION
The minimum bend radius for a 50 micron cable is 2 in. under full tensile load and 1.2 in. with no
tensile load.
Cables can be organized and managed in a variety of ways: for example, using cable channels on
the port or nonport sides of the cabinet or patch panels to minimize cable management. With the
horizontal orientation of the blades in the DCX-4S, a pair of vertical cable management finger
assemblies have been provided to keep the cables from hanging down in front of other blades.
Following is a list of recommendations:

the transceiver into the port until it is firmly seated and the latching mechanism clicks.
Transceivers are keyed so that they can only be inserted with the correct orientation. If a
transceiver does not slide in easily, ensure that it is correctly oriented.
the slot in the transceiver. Insert the cable into the transceiver until the latching mechanism
clicks.
Cables are keyed so that they can be inserted in only one way. If a cable does not slide in
easily, ensure that it is correctly oriented.
step 1 and step 2
•
Leave at least 1 m (3.28 ft) of slack for each port cable. This provides room to remove and
replace the PowerConnect B-DCX-4S, allows for inadvertent movement of the rack, and
helps prevent the cables from being bent to less than the minimum bend radius.
•
If ISL Trunking is in use, group the cables by trunking group. The ports are color-coded to
indicate which ports can be used in the same ISL Trunking group: eight ports marked with
solid black ovals alternate with eight ports marked with oval outlines.
•
For easier maintenance, label the fiber optic cables and record the devices to which they
are connected.
•
Route the cables to both the left and right sides of the DCX-4S through the cable
management fingers.
