Connections
An improperly connected cable may damage user files and other resources.
To prevent cables from being improperly connected, attach "destination labels" to cables and cabinets
during on-site installation.
To prevent signal cables of file system devices from being improperly connected during on-site
installation or expansion, be sure to attach "destination labels" to both ends of each cable.
Following the procedure described below, affix a unit label with a unit identifier written on it to the
unit cabinet, and use ties to attach cable labels with the cable destination written on them to both ends
of each cable.
(1) Work preparations
- Labels (consumable tool)
One label is required for each unit. Size: 50 x 15 (mm)
- Cable labels with ties (consumable tool)
Two labels are required for each cable.
(2) Work procedure
1) For each unit, write down a unit identifier on a label, and affix the label near the file system
connector port on the unit. Also write down the unit identifier on the installation drawing
(cable connection diagram).
Unit label: Size: 50 x 15 mm
If the label is too large, cut it to the appropriate size.
X: Unit symbol (See the table below.)
y: Unit number (Generally, unit numbers in a rack are assigned 1, 2, and so on in order by unit location
from left to right and bottom to top. However, they can be properly assigned (in a way that is easily
comprehensible) according to the unit installation locations in the system).
