Connecting Two MultiSwitch 924TXGs in 2-Wire Mode
There are two port-ranges relevant when connecting two MultiSwitch 924TXGs on the backplane using the
2-wire mode subtype. The two ranges are: Ports 7-9, 19-21; and Ports 10-12, 22-24.
NOTE
A port on one MultiSwitch 924TXG may only be connected to a port within the same
range on the other MultiSwitch 924TXG. For example, port 7 on one module may be
connected to any port 7-9, 19-21 on the other module. Port 10 on one module may be
connected to any port 10-12, 22-24 on the other module.
Hot-Swapping Modules
Hot-swapping is the insertion or removal of a module residing in a DIGITAL MultiSwitch 900 chassis or
in a DIGITAL MultiSwitch 900-4 chassis without disrupting power to the chassis.
CAUTION
Do not hot-swap more than one
module into or out of a DIGITAL MultiSwitch 900
at a time. Simultaneously inserting or removing more than one module can cause
problems with the operation of other installed modules.
Hot-Swapping GBICs
CAUTION
Do not install or remove a Gigabit (GBIC) card while the 924TXG module is
powered on. GBICs must not be hot-swapped; they must only be inserted in
or removed from a module that is powered off.
Refer to the detailed instructions supplied with the GBIC card for installation/removal procedures.
Diagnostics
If the diagnostic test fails, the module will not complete the power-up cycle. Access may still be gained
through the 924TXG console.

Xmodem Upgrades
Do not attempt an Xmodem upgrade unless everything is in place to follow through. Not doing so may force
you to power down the module to restart it.
