Card Installation and Node Startup 3-1

Card Installation and Node Startup

This chapter covers the following topics:

•How to install the cards in an IGX node that has arrived without cards already installed. (The

rack-mount models of the IGX 8420 and IGX 8430 nodes arrive with cards not installed.)

•Information unique to each card type that applies to bringing up the node and the network.

•Connections to LAN, modem, and printer ports.

•Checklist of readiness before you attempt to bring up the node.

•The commands and steps for bringing up the node and each type of card set in the node.

•Power-up diagnostics.

•IGX conﬁguration summary and IGX management.

Preparing the Cards

The locations of the system cards in the IGX node depend on the hardware conﬁguration. Primary

and redundant NPMs must reside in front slot 1 and 2. The SCM must reside in back slot 1. Except

for these reserved slots, cards can reside in any slot on the appropriate side of the node (but Cisco

recommends that the optional ARM/ARI card set reside in the slot on the far right).

Before you install cards in a rack-mounted IGX 8420 or IGX 8430 node, to indicate whether the

system is an IGX 8420 or an IGX 8430 node, you must either remove or leave a jumper switch on

the SCM. (For the IGX 8410 node and standalone IGX 8420/8430 systems, Cisco sets the switch at

the factory.) The switch is W6. It sits above component U7P (near the top of connector P2). To

indicate an IGX 8430 node, remove the jumper. To indicate an IGX 8420, leave the jumper. Make a

record of this step so you do not have to remove the SCM later to check it. See Figure 3-1.

Many card sets support Y-cable redundancy. This feature requires an extra set of cards and a Y-cable.

A set of commands exists to specify, delete, and display Y-cable redundancy. For instructions on

setting up Y-cable redundancy, refer to the setup section for the speciﬁc card set.

Note FRM and NTM front cards exist in one and two-piece versions. The two-piece card uses an

ACM1. Refer to the Cisco IGX 8400 Series Reference for details.

A Cisco IGX node can support a conﬁguration of up to 32 trunks.

Caution Connector pins must align with receptacles. Before card insertion, make sure that pins are

straight and that card connectors and the backplane align. Insert the card gently. It might be

necessary to push the edge of the card slightly to one side for alignment (this might require removing

cards).

The locations for the NPMs and SCMs in a Cisco IGX:

•Non-Redundant:

—NPM in front slot number 1

—SCM in back slot number 1 behind NPM front slot number 1

•Redundant:

—NPMs in front slot numbers 1 and 2

—SCM in back slot number 1 behind NPM front slot number 1

Note Opening the door requires a 5/32-inch Allen wrench. Cisco provides this in a combination

tool (Part No. 218705).

Caution When handling the cards, wear a wrist strap to prevent damage to the cards from electrostatic

discharge. The IGX 8410 cabinet has an attached wrist strap both at the front and back.

Inserting the Cards

To insert a Cisco IGX module:

Step 1 Attach an ESD-preventive wrist strap to handle the cards.

Note The IGX 8410 cabinet has an attached wrist strap both at the front and back.

Step 2 Using the 5/32-inch Allen wrench, open the Cisco IGX 8400 Series switch door.

Step 3 Be sure that you are inserting the module into the correct slot.

Step 4 Grasp the card front panel with one hand and place your other hand under the card to

balance the weight of the card as you push it vertically into the slot. (See Figure 3-6.)

Figure 3-6 Inserting Modules

Step 5 Push down on the ejector levers to properly seat the card.

Caution Always use the ejector levers when disengaging or seating the modules. Failure to do so can cause

erroneous system error messages, and indicate card failure. However, do not use the ejector levers to lift or

support the weight of the cards.

Step 6 Using the number 1 Phillips screwdriver, tighten the panel fasteners at the top and bottom

of the card front panel.

•OC3 (STM1)

•T3/E3

•T1/E1

•Subrate (less than T1 or E1 rates)

•Y1

Connecting Trunks

The sections that follow contain basic information on how to set up the two types of trunks on the

IGX node. The two trunk types are FastPacket and ATM. The supported line types are OC3/STM1,

T3, E3, T1, Y1, and E1. The card sets described in this section are the network trunk module (NTM).

The universal switching module (UXM-E) is a dual-purpose, ATM cell-based card and has its own

section that includes information for trunk-mode conﬁguration and port-mode conﬁguration.

Setting Up a UXM-E

To set up a UXM-E attach cables and enter commands at the command-line interface (CLI). For

detailed information regarding the UXM-E, refer to the Cisco IGX 8400 Series Reference. The

CiscoIGX8400SeriesReferencecontainscrucialinformationon,forexample,supportedendpoints,

connection types, allocation of cellbus bandwidth, and the logical trunk feature called Inverse

Multiplexing Over ATM (IMA).

You can specify the mode of the UXM-E through Cisco WAN Manager or the CLI. The UXM-E

card set goes into the mode determined when you activate the ﬁrst port. If you activate a logical port

to be a trunk by using the uptrk command, for example, the UXM-E goes into trunk mode. If you

use upln to activate a line as a UNI port to CPE or an NNI to another network, the UXM-E goes into

port mode.

For a summary of commands you use to bring up an IGX node, refer to the section “IGX

Conﬁguration Summary” on page 49 at the end of this chapter.

Bringing Up a UXM-E Trunk

If you are not familiar with precautions for card insertion, see the section “Preparing the Cards” on

page 1.

To attach the cables to a back card:

Step 1 Bring each cable through the opening at the top or bottom of the cabinet (however

appropriate) and along the back of the IGX enclosure. (See Figure 3-7.)

Step 2 If the unit has the optional cable manager, you can use it to help route the cables. (See

Figure 3-7.)

Step 3 Connect the cables to the connectors on the back card. (See Figure 3-7.)
