CHAPTER 2

INSTALLATION


This Ch a pter describes t he netw ork a nd power requirements a nd

operating specifications for the MRX, MRX-2, MRXI, and MRXI-2

10B ASE -T HU B s. B efore you at tempt to insta ll a ny of these HU B s,

review the inst a llation requirements a nd opera ting specifica tions

tha t a re outlined in this cha pter. Your network insta llation must

meet t he condit ions, guidelines, specifica tions, a nd r equirements

included in this chapt er to obta in sa tisfa ctory performa nce from this

equipm ent . Fa ilure to follow th ese guidelines could produce poornetw ork performa nce.

2.1 NETWORK REQUIREMENTS

Ta ke ca re in plann ing a nd prepar ing t he ca bling an d connections for

your netw ork. The qua lity of the connections, the length of ca bles

a nd other condit ions of th e inst a llat ion a re critical fa ctors in

determining th e relia bility of your netw ork. The follow ing sections

describe the netw ork requirement s to operat e this equipment.

2.2 SELECTING A LOCATION FOR THE HUB

The HU B can be ra ck mounted, w a ll mount ed, or placed on a ny

horizont a l surfa ce. If not inst a lled in a 19-inch rack, the follow ing

requirements m ust be met w hen selecting a loca tion for your H U B .

NOTE : Be sur e th at t he l ocati on sel ected i s w i th i n r each of th e

network cabl i ng.

An unrestr icted free surface a rea 21 inches wide, 18 inches deep

a nd 6 inches high is n eeded.

A single phase 120 Va c, 15A, grounded power recepta cle must be

locat ed w ithin 7 feet of th e site.


13/62

P a ge 2-2


I f a shelving unit i s to be used, i t must be ab le to suppor t

30 pounds of sta tic weight .

The tempera ture for the selected loca t ion must be mainta ined

between 5 a nd 50 C, a nd less tha n 10 C per hour t emperat urechange.

2.3 NETWORK GUIDELINES

The follow ing net w ork design guidelines m ust be follow ed w hen

connecting t he HU B to your netw ork:

As a genera l rule, 130 meters is the maximum length for an

unshielded tw isted pair segment. How ever, losses int roduced by

connections a t punch-down blocks a nd oth er equipment serve to

reduce th is limit. In most inst a llat ions, the optima l unshielded

tw isted pair length is 100 meters using sta nda rd P VC phone w ire.

Maximum link length is largely dependent on cable qua lity. I f

high qua lity, low a tt enuat ion cable is used, link lengths of up to

200 meters a re a chieva ble.

The device a t the other end of the twis ted pa ir segment mustmeet IE E E 802.3 10B AS E -T specifica tions.

The t ransceivers tha t w i ll be connected to the HU B (via a

SP IM-A) must m eet I EE E 802.3 sta nda rds a nd must n ot ha ve the

SQE test function ena bled.

2.3.1 10BASE-T Twisted Pair Network Requirements

When connecting a 10B ASE -T Tw isted P a ir Segment a t a ny of the10B ASE -T Tw isted P a ir HU B P orts (P ort s 1 th rough 12, a Single P ort

10BASE-T Twisted Pair Segment Interface module [SPIM-T or

SP IM-T1]), t he follow ing net w ork r equirements must be met:

Length - The IE EE 802.3 10BASE-T st a nda rd requires t ha t10B AS E -T devices t ra nsm it over a 100 meter (328 foot) link usin g

22-24 AWG uns hielded t w ist ed pa ir w ire.


14/62


Page 2-3

As a genera l rule, links up to 130 meters in length for un shielded

tw isted pair a nd 200 meters in length for shielded t w isted pair

a re achievable. For each connector or pat ch pan el in the link,

subtr a ct 12 meters from t he 150 meter limit . This w ill allow for

links of up to 126 meters using st a nda rd 24 AWG U TP w ire an dtw o pat ch pa nels within the link. Higher quality low a tt enuat ion

ca bles ma y be required w hen using links of great er tha n 126

meters. Due to ca ble dela y, the ma ximum link length is alw a ys

limited t o 200 meters, r ega rdless of the cable ty pe.

Insertion Loss -The ma ximum insertion loss a llow ed for a10B ASE -T link is 11.5 dB a t a ll frequen cies betw een 5.0 a nd 10

MH z. This includes the a tt enua tion of the cables, connectors,

pat ch pa nels, an d reflection losses due to impeda nce misma tches

in the link segment .

Impedance -U nshielded tw isted pa ir ca bles typica lly ha ve animpedan ce of betw een 85 to 110 ohms. Sh ielded tw isted pa ir

cables, such a s IB M Type 1 cable, ca n a lso be used. You should

remember th a t t he impedan ce of IB M Type 1 cable is typica lly

150 ohms. This increases th e signa l reflection ca used by th e

cable, but since the ca ble is shielded, this signa l reflection ha s

litt le effect on t he received signa ls qu a lity du e to the la ck of

crossta lk betw een th e shielded cable pairs. Ca bletron Syst ems10B ASE -T Tw isted P a ir products w ill work on t w isted pa ir cable

w ith 75 to 165 ohm s impeda nce.

J itter -Int ersymbol interference a nd reflections can ca use jitt erin th e bit cell timing, result ing in da ta errors. A 10B ASE -T link

must not generat e more tha n 5.0 nsec. of jitt er. If your ca ble

meets t he impeda nce requirements for a 10B ASE -T link, jitt er

should not be a concern.

Delay -The maximum propagation delay of a 10BASE-T linksegm ent m ust not exceed 1000 nsec. This 1000 nsec. ma ximum

dela y limits the ma ximum link segment length t o no great er tha n

200 meter s.

Crosstalk-Cr ossta lk is ca used by signal coupling betw een th edifferent ca ble pairs cont a ined wit hin a mult i-pair ca ble bundle.

10B ASE -T tr a nsceivers a re designed so tha t th e user does not

need t o be concerned a bout cable crosst a lk, provided t he cable

meets a ll other r equirements.


15/62

P a ge 2-4


Noise -Noise ca n be ca used by either crosst a lk or externa llyinduced impulses. Im pulse noise ma y ca use da ta errors if th e

impulses occur a t very specific tim es during da ta tr a nsmission.

G enera lly, the user need not be concerned a bout n oise. If noise-

rela ted da ta errors a re suspected, it ma y be necessary t o eitherreroute th e ca ble or elimina te t he source of t he impulse noise.

Temperature - Mult i-pa ir P VC 24 AWG t elephone ca blesty pica lly ha ve a n a tt enua tion of approxima tely 8 to 10 dB /100 m

a t 20 C (78 F). The a tt enua tion of P VC insula ted ca ble va ries

significa ntly with tempera ture. At tempera tures great er tha n

40 C (104 F), it is st rongly recomm ended tha t y ou use plenum -

ra ted ca bles to ensure tha t cable a tt enuat ion remains w ithin

specification.

2.3.2 Fiber Optic Network Requirements

When connecting a Fiber Optic Link S egment to the H U B w ith a

Sing le P ort Fiber Optic Interfa ce module (SP IM-F1 or S P IM-F2), th e

follow ing netw ork requirement s must be met:

Cable Type - The SP IM-F1 a nd S P IM-F2 a re designed for use

w ith one of t he follow ing m ultimode fiber optic media:

- 50/125 m fiber optic ca bling.

Budget and Propagation Delay - When determining thema ximum fiber optic ca ble length , th e fiber optic budget delay

a nd tota l network propaga tion should be ca lculat ed and ta ken

into consideration before fiber optic cable runs are incorporated in

a ny netw ork design. Fiber optic budget is the combina tion of theoptica l loss due t o the fiber optic cable, in-line splices, a nd fiber

optic connectors. P ropa ga tion dela y is th e a mount of time it ta kes

a packet t o tra vel from t he sending d evice to th e receiving device.
