The HP AdvanceStack Switch 208T and 224T are low-latency, high-speed
switches that you can use to build high-performance switched workgroup
networks.
The two switch models are:
Throughoutthismanual,theseswitcheswillbeabbreviatedastheSwitch208T
and Switch 224T, or, when common characteristics are being described, as
the Switch 208/224.
The Switch 208T and 224T haveeight and twenty-four10Base-T ports,respec-
tively, and two100Base-Tports: onefixedRJ-45 portand onetransceiverslot
for installing an HP 100Base-TX or 100Base-FX Transceiver Module.
With these switches you can build a switched network infrastructure by
connecting hubs or other switches, or you can connect computers, printers,
and servers to these switches to provide dedicated bandwidth to those
devices.
This chapter shows you how to install your Switch 208T or 224T.

Installation Steps
Installing theSwitch208/224
1. Prepare the Installation Site
■Cabling Infrastructure - Ensure that the cabling infrastructure meets
the necessary network specifications:
• Forthe10Base-Tports,usecategory3,4,or5,four-pair,100ohmUTP
(unshielded twisted-pair) cables. Cable lengths can be up to 100
meters for category 3 or 4, and 150 meters for category 5. For
connectingtheseportstoend nodes,use“straight-through”cable;for
connecting to hubs or other switches, use “crossover” cable. See
appendix A, “Cables and Connectors” for more information
• For the fixed 100Base-TX port and 100Base-TX transceivers that you
install in the transceiver slot, use category 5, 100-ohm UTP cables.
Cable lengths can be up to 100 meters.
Forconnectingtheseportstoendnodes,use“straight-through”cable;
for connecting to hubs and switches, use “crossover” cable.
• For 100Base-FX transceivers that you install in the transceiver slot,
use 1300 nm multi-mode fiber-optic cables that are fitted with SC
connectors, and conform to ISO/IEC 793-2 type B1 and ITU-T G.652
standards. Cable lengths can be up to 1 kilometer.
■Installation Precautions -
• Before installing theswitch, plan its location and orientation relative
to other devices and equipment. In the front of the switch, leave at
least 3 inches (7.6 cm) of space for the twisted-pair and fiber-optic
cabling. In the back, leave at least 1 1/2 inches (3.8 cm) of space for
the power cord.
•Caution: Ensure that the switch does not overload the power
circuits, wiring, and over-current protection. To determine the possi-
bility of overloading the supply circuits, add together the ampere
ratings of all devices installed on the same circuit as the switch and
compare the total with the rating limit for the circuit. The maximum
ampere ratingsare usuallyprinted on thedevices near the AC power
connectors.
•Caution: Ensure that the power source circuits are properly
grounded. See the Safety Statements at the end of this manual.
• Do not install the switch in an environment where the operating
ambient temperature might exceed 55°C (131°F).
• Makesure theairflowaroundthe sidesof the switchisnotrestricted.

3. Verify the Switch’s Operation
After you have installed any modules, but before mounting the switch in its
networklocation,youshouldfirstverifythatitisworkingproperlybyplugging
it into a power source and verifying that it passes its self test.
1. Connectthepowercordsuppliedwiththeswitchtothepowerconnector
on the back of the switch, and then into a properly grounded electrical
outlet.
Note The Switch 208/224 does not have a powerswitch.It is powered on when the
power cord is connected to the switch and to a power source.
If yourinstallation requires adifferent power cord than theone supplied with
the switch, be sure to use a power cord displaying the mark of the safety
agencythatdefinestheregulationsforpowercordsinyourcountry.Themark
is your assurance that the power cord can be used safely with the switch.
2. Check the LEDs on the switch’s front panel (and on the Switch Manage-
ment Module, if one is installed in the switch). The LED behavior is
described on the next page.

When the switch is powered on, it performs its diagnostic self test. With
the Switch Management Module installed, the self test takes approxi-
mately15secondsto complete.WithouttheSwitchManagementModule,
the test completes in approximately 4 seconds.
LED Behavior:
During the self test:
• Initially, all LEDs are on.
• With a Management Module installed, the switch port LEDs all go off
after approximately 10 seconds, and the Management Module Self
Test and Fault LEDs stay on for an additional 5 to 7 seconds.
When the self test completes successfully:
• The PowerLED and, ifan RPS is connected, the RPS LED remain on.
The “100” LED for port A also stays on.
• TheFaultLEDonthe switch,andthe SelfTestandFaultLEDsonthe
Management Module go off.
• The port LEDs go into their normal operational mode, if they are
connected to active network devices.
If the LED display is different than what is described above, especially if
anyFaultLEDs stayonformorethan30 seconds or flash,the selftesthas
not completed correctly. Refer to chapter 3, “Troubleshooting” for diag-
nostic help.
