Maintaining the Server

This chapter describes how to diagnose server system problems using LEDs. It also provides information

about how to install or replace hardware components, and it includes the following sections:

•Server Monitoring and Management Tools, page 3-1

•Status LEDs and Buttons, page 3-2

•Preparing for Server Component Installation, page 3-8

•Installing or Replacing Server Components, page 3-11

•Service DIP Switches, page 3-67

Server Monitoring and Management Tools

Cisco Integrated Management Interface

You can monitor the server inventory, health, and system event logs by using the built-in Cisco Integrated

Management Controller (Cisco IMC) GUI or CLI interfaces. See the user documentation for your

firmware release at the following URL:

http://www.cisco.com/en/US/products/ps10739/products_installation_and_configuration_guides_list.html

Server Configuration Utility

Cisco has also developed the Cisco Server Configuration Utility for C-Series servers, which can aid and

simplify the following tasks:

•Monitoring server inventory and health

•Diagnosing common server problems with diagnostic tools and logs

•Setting the BIOS booting order

•Configuring some RAID configurations

•Installing operating systems

You can download the ISO image from Cisco.com. See the user documentation for your version of the

utility at the following URL:

Internal Diagnostic LEDs

The server has internal fault LEDs for CPUs, DIMMs, fan modules, SD cards, the RTC battery, and the

mLOM card. These LEDs are available only when the server is in standby power mode. An LED lights

amber to indicate a faulty component.

See Figure 3-3 for the locations of these internal LEDs.

Preparing for Server Component Installation

This section describes how to prepare for component installation, and it includes the following topics:

•Required Equipment, page 3-8

•Shutting Down and Powering Off the Server, page 3-8

•Removing and Replacing the Server Top Cover, page 3-9

•Serial Number Location, page 3-10

•Hot-Swap or Hot-Plug Replacement, page 3-10

Required Equipment

The following equipment is used to perform the procedures in this chapter:

•Number 2 Phillips-head screwdriver

•Electrostatic discharge (ESD) strap or other grounding equipment such as a grounded mat

Shutting Down and Powering Off the Server

The server can run in two power modes:

•Main power mode—Power is supplied to all server components and any operating system on your

drives can run.

•Standby power mode—Power is supplied only to the service processor and the cooling fans and it

is safe to power off the server from this mode.

You can invoke a graceful shutdown or a hard shutdown by using either of the following methods:

•Use the Cisco IMC management interface.

•Use the Power button on the server front panel. To use the Power button, follow these steps:

Step 1 Check the color of the Power Status LED (see the “Front Panel LEDs” section on page 3-2).

•Green—The server is in main power mode and must be shut down before it can be safely powered

off. Go to Step 2.

•Amber—The server is already in standby mode and can be safely powered off. Go to Step 3.

Step 2 Invoke either a graceful shutdown or a hard shutdown:

Caution To avoid data loss or damage to your operating system, you should always invoke a graceful shutdown

of the operating system.

•Graceful shutdown—Press and release the Power button. The operating system performs a graceful

shutdown and the server goes to standby mode, which is indicated by an amber Power Status LED.

•Emergency shutdown—Press and hold the Power button for 4 seconds to force the main power off

and immediately enter standby mode.

Step 3 Disconnect the power cords from the power supplies in your server to completely power off the server.

Chapter 3 Maintaining the Server

Preparing for Server Component Installation

Removing and Replacing the Server Top Cover

Step 1 Remove the top cover (see Figure 3-4).

a. If the cover latch is locked, use a screwdriver to turn the lock 90-degrees counterclockwise to unlock

it. See Figure 3-4.

b. Lift on the end of the latch that has the green finger grip. The cover is pushed back to the open

position as you lift the latch.

c. Lift the top cover straight up from the server and set it aside.

Step 2 Replace the top cover:

Note The latch must be in the fully open position when you set the cover back in place, which allows

the opening in the latch to sit over a peg that is on the fan tray.

a. With the latch in the fully open position, place the cover on top of the server about one-half inch

(1.27 cm) behind the lip of the front cover panel. The opening in the latch should fit over the peg

that sticks up from the fan tray.

b. Press the cover latch down to the closed position. The cover is pushed forward to the closed position

as you push down the latch.

c. If desired, lock the latch by using a screwdriver to turn the lock 90-degrees clockwise.

Serial Number Location

The serial number for the server is printed on a label on the top of the server, near the front.

Hot-Swap or Hot-Plug Replacement

Some components can be removed and replaced without powering off and removing AC power from the

server. This type of replacement has two varieties: hot-swap and hot-plug.

•Hot-swap replacement—You do not have to precondition or shut down the component in the

software before you remove it for the following components:

–

SAS/SATA drives

–

Cooling fan modules

–

Power supplies (when 1+1 redundant)

•Hot-plug replacement—You must take the component offline before removing it for the following

component:

–

NVMe PCIE SSD drives
