DS-DSGGC-AA/AB) before you can manage the switch via a
telnet session, SNMP, or the Web.
The DS-DSGGC-AA/AB Fibre Channel switches have a default IP
address of 10.77.77.77. You may need to change this IP address
before you connect the switch to the network.
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 Gigabit Interface Converter (GBIC) modules. The GBIC
module is the electrical-to-optical converter.
The shortwave GBIC supports 50-micron multimode fiber (MMF) using the
standard subscriber connector (SC) connector. The longwave GBIC supports
9-micron, single-mode fiber-optic 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 fiber-optic cables are supported between switches in a cascaded
switch configuration.
______________________ Note _______________________
If you need to install additional interface modules in the
DSGGA switch, do so before you place the switch in a relatively
inaccessible location because you have to remove the top cover to
install the interface modules.
The DSGGB switch accommodates up to 8 (DS-DSGGB-AA) or 16
(DS-DSBBG-AB) GBIC modules.
The DS-DSGGC-AA switch has seven fixed shortwave optical transceivers
and one removable GBIC.
The DSGGC-AB switch accommodates up to 16 GBIC modules.
6.8.1.1 Installing the Switch
Place the switch within 500 meters (1640.4 feet) 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.
