6.5 Installing and Configuring Fibre Channel Hardware
This section provides information about installing the Fibre Channel
hardware needed to support Tru64 UNIX or a TruCluster Server
configuration using Fibre Channel storage.
Ensure that the member systems, the Fibre Channel switches, and the
HSG80 array controllers are placed within the lengths of the optical cables
you will be using.
______________________ Note _______________________
The maximum length of the optical cable between the KGPSA and
the switch or switch and the HSG80 array controller is 500 meters
via shortwave multimode Fibre Channel cable. The maximum
distance between switches in a cascaded switch configuration is
10 kilometers using longwave single-mode fiber.
6.5.1 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 or
DS-DSGGB-AB) full-duplex 1.6025 Gbits/sec ports. Each switch port can be
connected to a KGPSA-BC or KGPSA-CA PCI-to-Fibre Channel host bus
adapter, an HSG80 array controller, or another switch.
Each switch, except the DS-DSGGB-AA and DS-DSGGC-AA, 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 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) before
you can manage the switch through a telnet session, SNMP, or
the Web.
