Cable Routing
Plan for cable routing before installing the library.
The top and bottom of the Base and Drive Module rear door have openings to allow for cable routing. The openings are 2.5 cm (1 inch) by 73 cm (29 inches).
Note:
The rear door has two square holes near the bottom on the face of the door. These are for access to the PDU on/off switch, not for cable routing.When routing cables, make sure to include locations for power, library control, and Ethernet cables. As a best practice, route power cables through one opening and signal cables through another opening.

Library Network Cables
Verify that you have the correct network cables before installing the library.
You can place the library in a 62.5-micron-cable Storage Area Network (SAN). However, the cable that connects the library to the network must be a 50-micron cable. Maximum supported cable distance depends on the link speed, the type of fiber (50 or 62.5 micron), and the device the library is attached to. The typical distances are:
- 8 Gbps = up to 21 m (69 ft) for 62.5-micron, 50 m (164 ft) for 50-micron
- 4 Gbps = up to 70 m (230 ft) for 62.5-micron, 150 m (492 ft) for 50-micron
- 2 Gbps = up to 150 m (492 ft) for 62.5-micron, 300 m (984 ft) for 50-micron
- 1 Gbps = up to 175 m (574 ft) for 62.5-micron, 500 m (1640 ft) for 50-micron
If your library attaches to a host bus adapter (HBA), refer to the HBA's documentation for the supported cable distances.
AC Power Cables
Plan for the locations of power cables and list the locations for their associated circuit breakers before installing the library.
Order appropriate cables for the power configuration.
