Replacing HDDs in MMS Servers

Overview

The AMX line of MAX-MMS servers support hot-swappable hard disk drives (HDDs), 
accessible behind the removable faceplate, on the front panel. Typically a new HDD 
will be required only if an existing one has failed. Only HDDs provided by AMX can be 
used as replacements in MMS servers, and in order to replace a HDD in an MMS 
server, the drive must be installed and authenticated according to the steps outlined in 
this document.

The MMS-01S, MMS-02S, MMS-04S and MMS-12S servers all utilize 250GB 

hard drives, and require the 

MMS-HDD250G

 250GB drive (

FG 2178-250

) for 

replacements.

The MMS-900 server utilizes 300GB hard drives, and requires the 

MMS-HDD300G

 

300GB drive (

FG 2178-300

) for replacements.

There are several operations that are required to successfully replace an HDD in a 
MMS server, all off which are described in this document:

1.

The physical removal of the damaged HDD, and the subsequent installation of 
the replacement HDD. 

2.

A rebuild of the RAID array on the new HDD (required in order to add it to the 
server’s RAID array). 

3.

Authentication of the new HDD with the MMS server. Note that before the HDD 
can be authenticated to the server it must first be added into the array.

Note

: The MMS-01S server does not utilize a RAID disk-drive system. In this case 

there is no need to rebuild the array (as described below), but the replacement HDD 
still needs to be authenticated (see “Step 4: Authenticate the New HDD” below).

Step 1: Identify the Drive That Needs To Be Replaced

To identify the drive that needs to be replaced, you’ll use the server’s built-in Disk 
Management Utility tool. This requires that you have a PC connected to the MMS:

If you intend to connect to the MMS via a LAN connection, verify that the PC is 

communicating properly with the network.

Use an RJ-45 twisted pair cable to connect the Ethernet port on the MMS to the 

LAN that your PC is on.

Once you have established communication between the MMS server and your PC, 
you’ll use your web browser to access the server’s Disk Management Utility interface 
to see which port has failed. You’ll need this information to identify the physical HDD 
that needs to be pulled from the unit and replaced:

1.

Launch a web browser (i.e. Internet Explorer).

2.

Enter the IP address of the target MMS server in the address bar (example: 
http://192.168.1.30:1080). You can use the WinMAX program to determine the 
server’s IP address (displayed in the System Information tab). 

Don’t forget to include the port number.

Note:

 If you are using Mozilla as your browser, you’ll need to override the secu-

rity that blocks port 1080. To unblock port 1080, add the following line (located at 

/usr/lib/mozilla/defaults/pref/all.js

):

pref(“network.security.ports.banned.override”,”1080”)

3.

Press 

Enter

 to open the Disk Management Utility - Home Page (FIG. 1).

4.

Click on the 

Configure

 tab at the top of the screen to access the 

Configure

 page 

(FIG. 2) which lists all drives in each array and their status. If a drive has failed, it 
will be labeled “Degraded” rather than “OK”. 

5.

Note the 

Port Number

 of the Degraded drive, and determine which physical 

drive needs to be replaced in the server, based on the charts in FIG. 3: 

Also note that the LED on the degraded drive should blink to indicate that it needs to 
be replaced.

Once you have determined which drive needs to be replaced, you can proceed to 
physically removing the bad drive, and installing the replacement drive (see reverse).
