Cable and Configuration Guidelines
FC4700-series storage systems require optical cable between servers,
switches, and SPs. The cabling between DPE and DAE enclosures
(1 m, 3.3 feet) is copper.
You can use any existing FDDI, multimode, 62.5-micron cable with
good connections to attach servers, switches, and storage systems.
These cables must be dedicated to storage-system I/O.
Table 6-1 Cable Types and Sizes
Component planning diagrams and worksheets follow.
Hardware Planning Worksheets
Following are worksheets to note hardware components you want.
Some installation types do not have switches or multiple servers.
Length Typical use
5 m (16.5 ft) or
10 m (33 ft) optical
Within one room, connecting servers to storage systems
(adapter must support optical cable) or connecting switches to
storage systems
50 m (164 ft) optical Within one building, connecting servers to storage systems
(adapter must support optical cable) or connecting switches to
storage systems
100 m (328 ft) optical Within one complex, connecting servers to storage systems
(adapter must support optical cable) or connecting switches to
storage systems
250 m (821 ft,.15 mi) optical
500 m (1642 ft,.31 mi) optical
1 m (3.3 ft) copper Within one cabinet, connects the DPE to a DAE
.5 m (1.7 ft) copper Within one cabinet, connects DAEs to DAEs
Optical cabling is 50 micron (maximum length is 500 m (1,650 ft) or 62.5 micron (maximum length is 300
m (985 ft). The minimum bend radius is 3 cm (1.2 in).
