Introducing IDS-4235 and IDS-4250
You can deploy IDS-4235 at 250 Mbps to provide protection in switched environments and on multiple T3 subnets. With the support of 10/100/1000 interfaces you can also deploy it on partially utilized gigabit links. The sensing interface and the command and control interface are both 10/100/1000BASE-TX. You can install the 4FE card to provide an additional four sensing interfaces. You can also install the optional 10/100/1000BASE-TX adapter card, which allows additional options for inline functionality beyond the 4FE card. For the procedure for installing optional PCI cards, see Installing Optional PCI Cards.
Note The 250-Mbps performance for IDS-4235 is based on the following conditions: 2500 new TCP connections per second, 2500 HTTP transactions per second, average packet size of 445 bytes, system running Cisco IPS 5.0 sensor software.
IDS-4250 supports a 500-Mbps speed and can be used to protect gigabit subnets and traffic traversing switches that are being used to aggregate traffic from numerous subnets. The sensing interface and the command and control interface are both 10/100/1000BASE-TX. The optional interface is 1000BASE-SX (fiber). You can now install a second SX card in the IDS-4250. In addition, you can upgrade IDS-4250 to full line-rate gigabit performance with the IDS Accelerator (XL) card. You can also install the 4FE card to provide an additional four sensing interfaces. There is also an optional 10/100/1000TX adapter card that allows additional options for inline functionality beyond the 4FE card. For the procedure for installing optional PCI cards, see Installing Optional PCI Cards.
Note The 500-Mbps performance for IDS-4250 is based on the following conditions: 2700 new TCP connections per second, 2700 HTTP transactions per second, average packet size of 595 bytes, system running Cisco IPS 5.0 software.
Or you can order IDS-4250-XL with the XL card already installed. At 1 Gbps, IDS 4250-XL provides customized hardware acceleration to protect fully saturated gigabit links as well as multiple partially utilized gigabit subnets.
Note The 1000-Mbps performance for IDS-4250-XL is based on the following conditions: 5000 new TCP connections per second, 5000 HTTP transactions per second, average packet size of 595 bytes, system running Cisco IPS 5.0 software.

Installing Spare Hard-Disk Drives
Do not install a second hard-disk drive in IDS-4235 or IDS-4250. The spare hard-disk drives are meant to replace the original hard-disk drives and are not meant to be used in conjunction with the original hard-disk drive. If you install two hard-disk drives in IDS-4235 or IDS-4250, they may not recognize the recover command used to recover the application partition.
If the original hard-disk drive becomes unusable, remove the hard-disk drive and insert the replacement hard-disk drive. For the procedure, see Removing and Replacing the SCSI Hard-Disk Drive.
The replacement hard-disk drive is shipped blank from the factory. You must reimage it. For the procedure, refer to Upgrading, Downgrading, and Installing System Images.
Upgrading the BIOS
If the BIOS version is earlier than A04 on IDS-4235 or IDS-4250, you must upgrade the BIOS before you install Cisco IPS 5.0 software.
Caution Do not apply this BIOS upgrade to appliance models other than IDS-4235 and IDS-4250.
Check the BIOS version before performing the following procedure. Reboot the appliance and watch for the BIOS version number. The following example shows BIOS version A03:
Phoenix ROM BIOS PLUS Version 1.10 A03
Cisco Systems IDS-4235/4250
Testing memory. Please wait.
If the version is A01, A02, or A03, you must upgrade the BIOS to version A04.
To create and boot the IDS-4235 and IDS-4250 BIOS upgrade diskette, follow these steps:
Step 1 Copy BIOS_A04.exe to a Windows system.
You can find the file in the /BIOS directory on the recovery/upgrade CD, or you can download it from Cisco.com. For the procedure for downloading Cisco IPS software from the Software Center on Cisco.com, see Obtaining Cisco IPS Software.
Step 2 Insert a blank 1.44-MB diskette in the Windows system.
Step 3 Double-click the downloaded BIOS update file, BIOS_A04.exe, on the Windows system to generate the BIOS update diskette.
Step 4 Insert the new BIOS update diskette in IDS-4235.
Caution Do not power off or manually reboot the appliance during Step 5.
Caution You cannot upgrade the BIOS from a console connection. You must connect a keyboard and monitor to the appliance so that you can see the output on the monitor.
Step 5 Boot the appliance and follow the on-screen instructions.
Step 6 Remove the BIOS update diskette from the appliance while it is rebooting, otherwise the BIOS upgrade will be started again.
Using the TCP Reset Interface
IDS-4250-XL has a TCP reset interface—INT0. IDS-4250-XL has a specific TCP reset interface because it cannot send TCP resets on its sensing ports.
If you have reset problems with IDS-4250-XL, try the following:
•Make sure the TCP reset interface of IDS-4250-XL (int0) is connected to the same switch as the sensing ports (int2 and int3) of the XL card.
•If the sensing ports are access ports (a single VLAN), you need to configure the reset port to be in the same VLAN.
Note If the two XL ports are access ports for different VLANs, you can only configure the reset port for one of these VLANs. You can use dot1q trunk ports to overcome this limitation.
•If the sensing ports are dot1q trunk ports (multi-VLAN), the sensing ports and reset port all need to have the same native VLAN, and the reset port needs to trunk all the VLANs being trunked by both the sensing ports.

•One cable-management arm
•One stop block
•One status-indicator cable assembly
•Ten 10-32 x 0.5-inch flange-head Phillips screws
•Releaseable tie wraps
Installing the Slide Assemblies
The rack is measured in rack units (RU). An RU is equal to 44 mm or 1.75 inches.
To install the slide assemblies, follow these steps:
Step 1 Remove the rack doors according to the documentation provided with the rack cabinet.
Step 2 Place a mark on the rack's front vertical rails where you want to locate the bottom of the appliance that you are installing in the rack cabinet.
Note The bottom of each 1-RU space is at the middle of the narrowest metal area between holes (marked with a horizontal line on some rack cabinets).
Step 3 Place a mark 44 mm (1.75 inches) above the original mark you made (or count up three holes) and mark the rack's front vertical rails to indicate where the appliance's upper edge will be located on the vertical rails.
Note Mark 1 RU (44 mm or 1.75 inches) of vertical space for each appliance you install in the rack.
Step 4 At the front of the rack cabinet, position one of the slide assemblies so that its mounting-bracket flange fits between the marks you made on the rack (see Figure 4-6).
Note The three holes on the front of the mounting bracket should align with the 3 holes between the marks you made on the vertical rails.
Step 5 Install two 10-32 x 0.5-inch flange-head Phillips screws in the mounting flange's top and bottom holes to secure the slide assembly to the front vertical rail (see Figure 4-6).
Figure 4-6 Slide Assemblies
Step 6 At the back of the cabinet, pull back on the mounting-bracket flange until the mounting holes align with their respective holes on the back vertical rail.
Step 7 Install three 10-32 x 0.5-inch flange-head Phillips screws in the mounting flange's holes to secure the slide assembly to the back vertical rail.
Step 8 Repeat Steps 3 through 7 for the remaining slide assembly on the other side of the rack.
Step 9 Ensure that the slide assemblies are mounted at the same position on the vertical rails on each side of the rack.
Installing the Appliance in the Rack
If you are installing more than one appliance, install the first appliance in the lowest available position in the rack.
Caution Never pull more than one component out of the rack at a time.
To install the appliance in the rack, follow these steps:
Step 1 Pull the two slide assemblies out of the rack until they lock in the fully extended position.
Caution Because of the size and weight of the appliance, never attempt to install the appliance in the slide assemblies by yourself.
Step 2 Remove the appliance front bezel by pressing the left side tab and pulling.
Step 3 Lift the appliance into position in front of the extended slides.
Step 4 Place one hand on the front-bottom of the appliance and the other hand on the back-bottom of the appliance.
Step 5 Tilt the back of the appliance down while aligning the back shoulder screws on the sides of the appliance with the back slots on the slide assemblies.
Step 6 Engage the back shoulder screws into their slots.
Step 7 Lower the front of the appliance and engage the front shoulder screws in the front slot behind the appliance release latch (see Figure 4-7).
The appliance release latch moves forward and then snaps back as the shoulder screw passes into the front slot.
Note Use the appliance release latch when you want to remove the appliance from the slide assemblies.

You can install the cable-management arm on the right or left of the rack cabinet. This procedure describes installing the cable-management arm in the right side of the rack cabinet, as viewed from the back.
Tip If you are installing several appliances in the rack, consider installing the cable management arms on alternating sides of the rack for ease in cable routing.
To install the cable-management arm, follow these steps:
Step 1 Facing the back of the rack cabinet, locate the latch on the end of the right slide assembly that you secured to the back vertical rail.
Step 2 Push the tab on the back end of the cable-management arm into the latch on the end of the slide assembly (see Figure 4-8).
Note The latch clicks when locked.
Step 3 Push the tab on the remaining free end (the front) into a mating latch on the inner segment of the slide assembly (see Figure 4-8).
Note The latch clicks when locked.
Step 4 Install a stop block on the latch on the end of the opposite slide assembly (see Figure 4-8).
Note The stop block prevents the backward travel of the cable-management arm and supports the weight of the arm with its load of installed cables.
Note The two-post rack kit has two stop blocks: one for right-side mounting, and one for left-side mounting. You can only install the proper stop block.
Figure 4-8 Cable-Management Arm
Step 5 Install the status-indicator cable plug into its connector (see Figure 4-9).
Step 6 Open the wire covers on the cable-management arm by lifting the center of the wire over the top of the embossed round button on the front of the forward part of the arm, and lifting the wire over the top of a similar round button on the back part of the arm.
The wire cover swings open to enable cables to be routed within the arm.
Step 7 Route the status-indicator end of the cable assembly through the cable-management arm, and install the indicator in its slot at the back end of the cable-management arm (see Figure 4-9).
Figure 4-9 Installing the Cable-Management Arm
Step 8 Connect the power cords to their receptacles on the back panel.
Note Although the strain-relief can accommodate power cords with a bend radius of up to 19 millimeters (0.75 inch), use only the power cords provided with the appliance.
Step 9 Install a tie-wrap through the slot on the strain-relief tab (see Figure 4-10).
Step 10 Bend the power cords back beside the power receptacle housing and form a tight loop. Install the strain-relief tie-wrap loosely around the looped power cord (see Figure 4-10).
Figure 4-10 Power Cord Strain Relief
Routing the Cables
To route the cables, follow these steps:
Step 1 Attach the I/O cable connectors to their respective connectors on the appliance back panel.
For details on the cable connections, see Installing IDS-4235 and IDS-4250.
Step 2 Route the power and I/O cables through the cable-management arm, using four loosely secured releaseable tie-wraps (two in the middle and on each end of the cable-management arm).
Note Do not fully tighten the tie-wraps at this time (see Figure 4-11). Allow some cable slack in the cable-management arm to prevent damage to the cables.
Figure 4-11 Routing Cables
Step 3 Secure the cables to the cable-management arm:
a. After connecting the cables to the appliance, unscrew the thumbscrews that secure the front of the appliance to the front vertical rail.
b. Slide the appliance forward to the fully extended position.
c. Route the cables along the cable-management arm, making any adjustments to the cable slack at the hinge positions, and secure the cables to the cable-management arm with the releaseable tie-wraps and the wire covers over the cable-management arm.
Note As you pull the appliance out to its farthest extension, the slide assemblies lock in the extended position. To push the appliance back into the rack, press the slide release latch on the side of the slide, and then slide the appliance completely into the rack.
Step 4 Slide the appliance in and out of the rack to verify that the cables are routed correctly and do not bind, stretch, or pinch with the movement of the cable-management arm.
Step 5 Make any necessary adjustments to ensure that the cable slack is neither too tight nor too loose, yet keeps the cables in place as the appliance is moved in and out of the rack.
Step 6 Replace the rack doors.
Note Refer to the procedures for replacing the rack doors in the documentation provided with the rack cabinet.

Warning Because of the size and weight of the rack cabinet doors, never attempt to remove or install them by yourself.

Two-Post Rack Installation
You can install the two-post rack (part number IDS-RAIL-2=) in a center-mount or flush-mount configuration. The two-post kit incorporates slide assemblies that enable the appliance to be pulled out of the rack for servicing.
You must properly secure the two-post, open frame relay rack to the floor, the ceiling or upper wall, and where applicable, to adjacent racks, using floor and wall fasteners and bracing specified or approved by the rack manufacturer.
|
Warning Do not attempt to install the appliance into a two-post, open-frame relay rack that has not been securely anchored in place. Damage to the appliance and injury to yourself and to others may result.

Recommended Tools and Supplies
You need the following tools and supplies to install the appliance in a two-post, open-frame relay rack:
•#2 Phillips screwdriver
•11/32-inch wrench or nut driver (if changing bracket to flush-mount configuration)
•Masking tape or felt-tip pen to mark the mounting holes
Rack Kit Contents
The two-post rack kit includes:
•One pair of slide assemblies (two-post)
•One cable-management arm
•One status-indicator cable assembly
•Two stop blocks
•Eight 12-24 x 0.5-inch pan-head Phillips screws
•Releaseable tie wraps
Marking the Rack
You must allow 1 RU (44 mm or 1.75 inches) of vertical space for each appliance you install in the two-post rack.
To mark the rack, follow these steps:
Step 1 Place a mark on the rack's front vertical rails where you want to locate the bottom of the appliance that you are installing in the two-post rack.
Note The bottom of each 1-RU space is at the middle of the narrowest metal area between holes.
Step 2 Place a mark 44 mm (1.75 inches) above the original mark you made.
Note Each 1 RU (44 mm, or 1.75 inches) of vertical space on a rack with universal-hole spacing has three holes with center-to-center spacing between the holes (beginning at the top of a 1-RU space) of 15.9 mm, 15.9 mm, and 12.7 mm (0.625 inches, 0.625 inches, and 0.5 inches).
Installing the Slide Assemblies in the Rack
You can install the slide assemblies in a two-post, open-frame relay rack having either universal-hole spacing or wide-hole spacing. You can install the 1-RU slide assemblies in either a flush-mount or center-mount configuration.
This section contains these topics:
•Center-Mount Installation
•Flush-Mount Installation
Center-Mount Installation
The two-post rack kit is shipped with brackets configured for center-mount installation.
To install the center-mount brackets, follow these steps:
Step 1 Locate the right slide assembly and push the back bracket toward the back of the slide assembly (see Figure 4-12).
Step 2 Position the right slide assembly in the two-post rack at the location you marked, push the back bracket forward against the vertical two-post rack, and secure the front and rear center-mounting brackets to the rack with two 12-24 x 0.5-inch pan-head Phillips screws (Figure 4-12).
Step 3 Repeat Steps 1 and 2 to install the left side assembly in the rack.

Flush-Mount Installation
To install the flush-mount brackets, follow these steps:
Step 1 Locate the two slide assemblies and place them, side by side, on a smooth work surface, with the front ends of the slide assemblies toward you. Position both slide assemblies so that the center brackets are facing upward (see Figure 4-13).
Note To prepare the slides for flush-mount installation, remove the front mounting bracket, rotate it 180 degrees, and reinstall it on the opposite slide assembly.
Step 2 Using a #2 Phillips screwdriver and an 11/32-inch wrench or nut driver, remove two 12-24 x 0.5-inch pan-head Phillips screws, two nuts, and two shoulder washers from each front center bracket (see Figure 4-13).
Step 3 Remove the front bracket from both slide assemblies.
Step 4 Place the bracket from one slide assembly onto the threaded studs on the opposite slide assembly, with the bracket turned 180 degrees so that the mounting flange faces forward (see Figure 4-13).
Step 5 Secure each front center mount bracket (by its nuts and shoulder washers) and tighten them by hand on their opposite slide assemblies using the two shoulder washers and two nuts you removed in Step 2 (see Figure 4-13).
Step 6 Join the front brackets you just installed to the bracket on the slide assembly with the two 12-24 x 0.5-inch pan-head Phillips screws you removed in Step 2 (see Figure 4-13).
The joined bracket becomes the new extended rear bracket.
