5. Slide the handle to the closed position.
6. Turn on the power to the HP AdvanceStack hub by plugging in the power
cord (there is no On/Off switch).
When power is applied, the hub will begin its power-on self-test, followed
by the module’s self-test. With the module installed, the combined self-
test time is approximately 20 seconds. (The module may perform a second
self-test; the second test is normal during the first power-up and can take
an additional 20 seconds.)
If the HP 100VG SNMP/Bridge Module is installed and functioning
correctly, the Expansion Slot (“Exp Slot”) LED on the front of the hub will
be lit (solidly ON) after the self-tests have completed. The following
illustration shows the location of the Exp Slot LED on the front of the HP
J2415A AdvanceStack 100VG Hub-14.
If the “Exp Slot” LED begins to blink at a higher rate than during
self-test and continues to blink for an extended period of time, refer to
chapter 4, “Troubleshooting” in this guide.
If you are connecting the SNMP/Bridge module to a busy 100VG network,
the 10 Mbit/s LED on the back of the module may flash slowly while the
bridge learns all of the addresses on the network. After a while, the LED
should stop flashing.
You have now completed installation and verification of the module.
Bridge Operation
The bridge feature of the HP 100VG SNMP/Bridge Module allows you to use
an HP AdvanceStack 100VG hub to connect a 100VG LAN to a 10 Mbit/s
Ethernet/IEEE 802.3 LAN. When using the bridge, an optional 10Base
transceiver module must be installed in the module and connected to an
Ethernet/IEEE 802.3 LAN.
