Installation Summary

This chapter describes the installation procedures for the HP J3245A
AdvanceStack Switch 800T (h er eafter referred to as the Switch 800T).
The following is a summary of those procedures:

1. Site Preparation. Ensure that the cabling infrastructure meets the
network specifications for your intended use of the Switch 800T.

• For 100Base-TX transc eivers used in the Swi tch 800T, us e categor y 5,

four-pair, 100 oh m UTP (unshielded twisted-pair) cabl es. Cable
lengths can be up to 100 meters. For a connection to an end node, use
straight-through cable. For a connection to a hub or a switch, use a
crossover cable.

• For 100Base-FX transcei vers used in the Switch 800T, use fiber

optical cable s that:
– Are fitted with type SC connectors
– Conform to ISO/IEC 793-2 type B1 and ITU-T G.652 standa rds

Caution Ensure that the power source circuits are adequate and properly

grounded. That is, ensure that any Switch 800T installation , together with
any other devices, does not overload the power circuits, wiring, and over­current protection. To determine the possibility of overloading the supply
circuits, add together the ampere ratings from the nameplates of all
devices installed o n the same circuits and compare the total with the
rating limits for the supply circuits. For additional information, refer to
appendix B, “Specifications”.

Installation Summary

2. Install transceivers (optional). The Swi t ch 800T is shipped wi th fo u r
HP J3192B AdvanceStack 10 0Base-TX Twis ted-Pair Transceive r Modules

(referred to in this manual as “trans ceiv ers”) already insta lle d.

Caution Because the Switch 800T can be damaged by installing or removing a

transceiver while powered-up, the ONLY time to install additional
transceivers is before powering up the switch or with the power
disconnected during scheduled down times.

The J3192A
Always use the “B” version (J 3192B

twisted-pair transceiver is not supported in the Switch 800T.

) or any later J3192 transceiver(s).

3. Verify the switch’s operation. This is a simple process of applying
power to the Switc h 800T and ensuring that the LEDs on the switch’s fr ont
panel respond properly.

4. Mount the switch in a rack, o n a wall, or on a tabletop.
Hewlett-Packard sells 19-inch free-standing eq ui p ment racks. To order a
rack, contact your HP-authorized LAN dealer.

5. (Optional) Connect the J2962A HP AdvanceStack Redundant

Power Supply (RPS) instead of using the switch’s own power
supply. This optional power supply can be used instead of the switch’s

main power supply to provide both primary and backup (redunda nt)
power to keep the switch operating in the event of a failure in either a
power circuit or a power supply unit.

6. Connect the Switch 800T to a network and co nnect computers and/

or other devices to the switch’s ports.

7. Configure the Switch 800T. The Switch 800T, in its factory default
configuration, operates as a multiport transparent bridge. You will ne ed
to use the console interface utility to configure the switch for additional
functionality. Initially, this requires one of the following:

• A PC with a terminal emulato r conn ected to the Consol e RS- 232 por t

on the switch either directl y or via a modem

• An actual terminal directly connected to the Consol e RS-232 port on

the switch

1-2

(For examples of terminal emulator configurations, refer to appendix C,
“Sample Console Configurations”. )

After configuring a minimal IP or IPX configuration through one of the
above options, you can also access the console interface via Telnet o r use
a network management tool, such as Hewlett-Pack ar d ’s AdvanceStack
Assistant, for some configuration and monitoring functions.

Twisted-Pair Transceiver Modules already installed. (The switch does not

support use of the “A” version—HP J3192A—o f t his tr an sceiver.) Additional
twisted-pair (UTP) or fiber transceivers must be purchased separately. (You
need a minimum of one transceiver inst alled to connect the switch to your
network, and one additional trans ceiver installed for each connectio n to a
server, hub, switch, or other device.) The Switch 800T is designed to operate
with either of the following two tran sceivers:

■ HP J3192B AdvanceStack 100Base-TX Twisted-Pair Transceiver Module

■ HP J3193B AdvanceStack 100Base-FX Fiber-Optic Transceiver Module

Caution To avoid damage to circuitry in the Switch 800T and transceivers,

always have the power to the Switch 800T turned off while a trans­ceiver is being installed or removed.

For proper cooling and for reduction of electromagnetic emissions, ensure
that a slot cover (provided with your Switch 800T) is installed on any unused
transceiver slot.

1. Install Add-In Transceivers (Optional)

It may be more convenient to install additional trans ceivers before install ing
the Switch 800T into a rack or other location. Inspect your installa tion site and

determine whether the switch’s module slots will be accessible.
For a description of cur r ently available transcei vers, contact your

HP-authorized LA N deal er or check Hewlett-Packard’s World Wide Web site
listed on the card at the front of this manual.

To Install a Transceiver into the Switch 800T: This procedure describes the general installation of a transce iver. For information on the specific transceiver you are installing, plus specific connection and trouble­shooting information, refer to the HP 100Base-T Transceiver Mod ules Installation Guide you received with the transceiver.

1. Unplug the Switch 800T from the AC power source.

Caution To avoid damage to circuitry in the Switch 800T and transceivers,

always have the power to the Switch 800T turned off while a
transceiver is being installed or removed.

2. Use a flat-bladed or Torx T-10 screwdriver to unscrew the two retaining
screws from the cover plate on the slot in which you want to install the
transceiver . For example, to i nstall an HP J3192B Advan ceStack 100Bas e­TX Twisted-Pair Transceiver Module for port 5:

Caution For proper cooling and reduction of electromagnetic emissions, ensure

that the slot cove rs (provid ed with your Switch 800T) are installed o n any
unused slots.

3. While constantly touching a metal part of the Switch 800T to discharge
any static electric difference between your body and the switch, carefully
remove the tra nsceiver from i ts protectiv e anti-st atic packagi ng. Hold the
transceiver b y its edges, ta ki n g care not to touch an y of its metal connec­tors.

4. Slide the transceiver firmly into the open slot as far as it will go. The

transceiver’s faceplate should touch the face of the device.

Note Ensure that the transceiver you are installing has a blue color bar with the

word “100T” printed on it ([ 100T ]). (See figure 1-3, below.) Any transceiver
that does not have this bar will not operate with the Switch 800T and will cause
a fault condition.

3. Mount the Switch

3. Mount the Switch

A Switch 800T can be mounted in two ways:

■ In a rack or cabinet

■ On a table

■ On a wall

The hardware for mounting the switch is included in the accessory kit
(5063-8544) packed with the switch.

Hewlett-Packard sells 19-inch free-standing equ ipment racks. For more
information, contact your HP authorized LAN dealer.

Mounting
Precautions

Before mounting the switch, read and follow these mounting precautions:

■ Plan the switch’s location and orientation relative to other devices and

equipment. Also consider the cabling that will be attached to the switch
and ports that will be used. In the front of the switch, leave 3 inches
(7.6 cm) of space for twisted-pai r cables. In the back of the switch, leave
1-1/2 inches (3.8cm) of space for the power cord.

■ Ensure that any installation of a Switch 800T, together with any other

devices, does not overload the power circuits, wiring, and over-current
protection. To determine the possibility of overloading the supply circuits,
add together the ampere ratings from the nameplates of all devices
installed on the same circuits and compare the total with the rating limits
for the supply circuits.

■ Make sure that the power source circuits are properly grounded, then use

the supplied power cord to connect the Switch 800T to the circuit. Refer
to the Safety and Regulatory Statements that follow the appendixes at the
back of this manual.

■ Do not install the Switch 800T in an environme n t where the operating

ambient temperature mi gh t exc eed 55°C (131°F).

■ For proper cooling, make sure the air flow around the sides and back of

the switch is not restricte d.

■ If an HP J2962A AdvanceStack Swit ch 800T Redundant Power Supply is

installed, make sure the air flow around the fan area of the RPS is not
restricted.
