6.8 Installing and Configuring Fibre Channel Hardware
This section provides information about installing the Fibre Channel
hardware that is needed to support Tru64 UNIX or a TruCluster Server
configuration using Fibre Channel storage.
Ensure that the member systems, the Fibre Channel switches or hubs, and
the HSG80 array controllers are placed within the lengths of the optical
cables that you will be using.
______________________ Note _______________________
The maximum length of the optical cable between the KGPSA and
the switch (or hub), or the switch (or hub) and the HSG80 array
controller, is 500 meters (1640.4 feet) via shortwave multimode
Fibre Channel cable. The maximum distance between switches
in a cascaded switch configuration is 10 kilometers (6.2 miles)
using longwave single-mode fiber.
6.8.1 Installing and Setting Up the Fibre Channel Switch
The Fibre Channel switches support up to 8 (DS-DSGGA-AA,
DS-DSGGB-AA, and DS-DSGGC-AA) or 16 (DS-DSGGA-AB,
DS-DSGGB-AB, or DS-DSGGC-AB) full-duplex 1.6025 Gb/sec ports. Each
switch port can be connected to a KGPSA-BC or KGPSA-CA PCI-to-Fibre
Channel host bus adapter, an HSG60 or HSG80 array controller, or another
switch.
Each switch, except the DS-DSGGB-AA and DS-DSGGC-AA/AB, has a front
panel display and four push buttons that you use to manage the switch.
Four menus allow you to configure, operate, obtain status, or test the switch.
The DS-DSGGB-AA and DS-DSGGC-AA/AB are managed through a telnet
session after the IP address has been set (from a PC or terminal).
All switches have a 10Base-T Ethernet (RJ45) port, and after the IP address
is set, the Ethernet connection allows you to manage the switch:
• Remotely using a telnet TCP/IP connection
• With the Simple Network Management Protocol (SNMP)
• Using Web management tools
______________________ Note _______________________
You have to set the IP address and subnet mask from the front
panel (or from a PC or terminal with the DS-DSGGB-AA or
