you can manage the switch by way of a telnet session, SNMP, or
the Web.
The DSGGA switch has slots to accommodate up to four (DS-DSGGA-AA) or
eight (DS-DSGGA-AB) plug-in interface modules. Each interface module in
turn supports two Giga Bit Interface Converter modules (GBIC). The GBIC
module is the electrical-to-optical converter.
The shortwave GBIC supports 50-micron multimode fibre (MMF) using
the standard subscriber connector (SC) connector. The longwave GBIC
supports 9-micron, single-mode fibre optical cables. Only the 50-micron
MMF optical cable is supported between the host bus adapters and switches
or switches and HSG80 controllers for the TruCluster Server product.
Longwave single-mode fibre optical cables are supported between switches
in a cascaded switch configuration.
______________________ Note _______________________
If you need to install additional interface modules, do so before
placing the switch in a relatively inaccessible location because
you have to remove the top cover to install the interface modules.
The DS-DSGGB switch accommodates up to 8 (DS-DSGGB-AA) or 16
(DS-DSBBG-AB) GBIC modules.
6.5.1.1 Installing the Switch
Place the switch within 500 meters of the member systems (with KGPSA
PCI-to-Fibre Channel adapter) and the HSG80 array controllers.
You can mount the switches in a 48.7-cm (19-in) rackmount installation or
place the switch on a flat solid surface.
When you plan the switch location, ensure that you provide access to the
front of the switch. All cables plug into the front of the switch. Also, for
those switches with a control panel, the display and switches are on the
front of the switch.
For an installation, at a minimum, you have to:
1. Place the switch or install it in the rack.
2. Connect the Ethernet cable.
3. Connect the fibre-optic cables.
4. Connect power to the switch.
