HP 100Base-T Hubs Installation and Reference Guide
Hot Swap
The HP 100Base-T Hubs support a “hot swap” capability that
allows you to connect/disconnect hubs or media connectors
from the system with minimal disruption to the network. You
can remove any network cabling without affecting traffic
passing across the internal repeater bus. However, if the
Stacking Cable is disconnected at any point in the stack, or is
not properly terminated, all Ethernet and management traffic
passing through the cable will be disrupted.

When changing modules in the Expansion Slot, first disconnect
power to the concerned hub.
Configuring a Manageable Stack
To manage the stack with the VT-100 console interface, the
stack must include a Hub-12TXM (i.e., a unit with an SNMP
agent).
You should also consider adding a backup SNMP agent to
provide greater management reliability for critical applications.
The procedures required to install these system components are
described below.
Installing an SNMP Backup Agent
The VT-100 console interface
only provides access to the
private MIB.
Just add the Hub-12TXM(s) to the stack and let the system
automatically choose the Master agent and the backup agent
based on position in the Stacking Cable chain. The Master
indicator on the device chosen as the primary agent will turn ON.
The Backup indicator will turn ON for all other Hub-12TXMs.
